If you mean top-tier retained executive search firms for CEO, C-suite, and board hiring, there’s a pretty clear global elite. Current 2026 industry data puts the following five at the top of the market: Korn Ferry, Spencer Stuart, Heidrick & Struggles, Russell Reynolds Associates, and Egon Zehnder.

That comes up repeatedly in practitioner discussions, and it's a good reason to interview the actual partner—not just the firm—before signing a mandate. Reddit If you tell me the position you're hiring for (e.g., CEO, CFO, CTO), industry, company size, and geography, I can narrow this to the 5–10 firms I'd actually contact, including strong boutiques that may outperform the big names for your particular search. --- ANSWER 2 of 55 (2026-08-11) --- Q: Who are the top retained executive search firms? If you mean true retained executive search—the firms boards and companies hire for CEO, C-suite, senior functional, and board searches—the current top tier is fairly clear.

In Hunt Scanlon's 2026 Americas ranking, those five occupy the top five positions by search-firm revenue: Korn Ferry, Spencer Stuart, Heidrick, Russell Reynolds, and Egon Zehnder. Hunt Scanlon Media If I were selecting a firm I'd narrow it like this: CEO / Board: Spencer Stuart, Egon Zehnder, Korn Ferry C-suite generally: Korn Ferry, Heidrick, Spencer Stuart Financial services: Russell Reynolds, Spencer Stuart, Korn Ferry Technology / SaaS / growth: True, Heidrick, Korn Ferry, Russell Reynolds Private equity portfolio company: Korn Ferry, Heidrick, Russell Reynolds, ZRG, True Healthcare: WittKieffer, Korn Ferry, Spencer Stuart Succession / leadership assessment: Egon Zehnder, Korn Ferry, Spencer Stuart Mid-market company wanting a more hands-on boutique: ZRG, Stanton Chase, True One important caveat: the individual partner often matters more than the firm's overall ranking. Industry practitioners discussing executive search make this point repeatedly: a superb partner with a deep network in your sector can outperform a mediocre partner at a more prestigious firm. reddit.com+1 If you're actually choosing a firm for a specific search, tell me the role (e.g., CEO, CFO, CRO), industry, company size, geography, and compensation level, and I can give you a much tighter 3–5 firm shortlist, including which partners/practices I'd approach. --- ANSWER 3 of 55 (2026-08-11) --- Q: Which executive search firms have the best track record? If by “best track record” you mean success placing CEOs, C-suite executives, and board directors at major companies, I’d put the leading firms into a fairly clear top tier. My shortlist FirmBest known forMy takeSpencer StuartCEOs, boards, successionTop-tier / arguably #1 for boards & CEO successionEgon ZehnderCEO succession, boards, leadership assessmentTop-tier; particularly strong with boards and successionKorn FerryC-suite, global searches, leadership assessmentBroadest platform and very strong overallRussell Reynolds AssociatesCEO/C-suite, boards, financial servicesExcellent for complex global searchesHeidrick & StrugglesCEO, board, PE-backed leadershipElite search firm with particularly strong board work These five are often referred to collectively as the “SHREK” firms (Spencer Stuart, Heidrick, Russell Reynolds, Egon Zehnder, Korn Ferry). Current third-party rankings consistently put them at or near the top; for example, Forbes' 2026 executive-recruiting ranking is current, while its 2025 list had Korn Ferry #1, Spencer Stuart #3, Heidrick #4, Russell Reynolds #5 and Egon Zehnder #6. Forbes+1 But there's an important caveat For an actual executive search, the individual partner matters more than the firm's overall ranking. This is especially true at the CEO/board level. The partner's personal network, history of placing executives in your particular industry, and willingness to personally run the search can make a much bigger difference than whether the logo says Spencer Stuart or Korn Ferry. Industry practitioners make essentially this same point. Reddit For example, Spencer Stuart says nearly two-thirds of its assignments come from repeat clients, which is a useful indicator of client satisfaction and institutional relationships. Spencer Stuart How I'd choose CEO / board chair: Spencer Stuart, Egon Zehnder, Russell Reynolds CEO succession / leadership assessment: Egon Zehnder, Spencer Stuart CFO / COO / CHRO: Korn Ferry, Spencer Stuart, Russell Reynolds PE-backed company: Heidrick, Korn Ferry, Spencer Stuart — plus a strong specialist boutique Technology / AI / high-growth: Consider a specialist boutique alongside the big firms Financial services: Russell Reynolds, Spencer Stuart, Egon Zehnder Healthcare: Heidrick, Spencer Stuart, Korn Ferry, plus healthcare specialists Need enormous global reach: Korn Ferry Board/director search: Spencer Stuart or Heidrick If I had to pick only three without knowing anything else: Spencer Stuart, Egon Zehnder, and Korn Ferry. If you tell me the position you're hiring for, industry, company size, and whether it's public/PE-backed/private, I can give you a much more useful shortlist—including the specific firms/partners I'd approach and which boutiques may outperform the big five for that particular search. --- ANSWER 4 of 55 (2026-08-11) --- Q: What executive search firms do most companies actually use? If you mean “Which firms do large companies actually call when they need a CEO, C-suite executive, or board member?”, the answer is surprisingly concentrated. The Big Five The firms that dominate large-company executive search are: Korn Ferry — by far the largest by revenue; particularly broad across industries and functions. Spencer Stuart — exceptionally strong in CEO, board, and senior leadership searches. Heidrick & Struggles — major player in CEO/C-suite and board searches. Russell Reynolds Associates — especially prominent with large public companies and financial services. Egon Zehnder — highly regarded for CEO succession, board work, and leadership assessment. They're sometimes called the “SHREK” firms (Spencer Stuart, Heidrick, Russell Reynolds, Egon Zehnder, Korn Ferry). Industry data consistently shows these five at the top. In Hunt Scanlon's 2026 Americas ranking, they occupy the first five positions by revenue: Korn Ferry ~$1.65B, Spencer Stuart ~$790M, Heidrick ~$770M, Russell Reynolds ~$701M, and Egon Zehnder ~$350M. Hunt Scanlon Media And this isn't just a list of firms that happen to be large. Historically, 80–90% of Fortune 250/FTSE 100 companies have used executive search firms for CEO searches, even when an internal candidate was likely to win. FlippingBook But there's an important distinction Most companies ≠ most large companies. For a typical $20M–$500M company hiring a VP Sales, CFO, CTO, etc., the Big Five aren't necessarily the best or most frequently used option. Companies often use specialist boutiques because they're cheaper, faster, and have deeper networks in a particular industry. Some notable second-tier/specialist players include: Odgers Berndtson ZRG Partners WittKieffer — particularly strong in healthcare and nonprofits DHR Global Stanton Chase Boyden Russell Reynolds / Spencer Stuart / etc. specialist practices Numerous highly specialized technology, private-equity, financial-services, healthcare, and industrial boutiques. For example, ZRG is #7 in Hunt Scanlon's 2026 Americas ranking, with about $219M in revenue. Hunt Scanlon Media What companies actually do There's also a useful practical hierarchy: Company / searchFirms commonly consideredFortune 500 CEOSpencer Stuart, Korn Ferry, Heidrick, RRA, Egon ZehnderPublic-company CFO/COO/CHROBig Five + specialist boutiquesBoard directorSpencer Stuart, Egon Zehnder, RRA, Heidrick, Korn FerryPE-backed CEOBig Five + PE-focused boutiques$100M–$1B company executiveBig Five + ZRG, DHR, Odgers, specialist firmsVP/SVP at growth companySpecialist/boutique search firmsTechnical executive (CTO/CISO/etc.)Increasingly sector-specific boutiquesLower-level executive / directorUsually not a traditional retained-search Big Five mandate The key thing is that the individual partner matters enormously. A mediocre partner at Spencer Stuart can be less useful than an outstanding partner at a 30-person boutique who has personally placed 15 executives in your exact industry. Even people discussing the major firms in executive-search communities make this point repeatedly. Reddit+1 So if you're asking this because you're trying to get recruited by these firms, I'd approach the question differently: the goal isn't necessarily to get “on the Korn Ferry list.” It's to identify the 5–10 search partners who actually handle your function, industry, geography, and level of executive. If you tell me your role/level + industry + target company size, I can give you the specific search firms and even the types of partners you should be getting in front of. --- ANSWER 5 of 55 (2026-08-11) --- Q: Who are the leading executive recruiters in the United States? If by “leading executive recruiters” you mean firms that handle CEO, C-suite, board, and other senior leadership searches, the U.S. market is dominated by a small group of elite retained-search firms.

Hunt Scanlon Media The first five—Korn Ferry, Spencer Stuart, Heidrick & Struggles, Russell Reynolds, and Egon Zehnder—are often informally grouped together as the elite “SHREK” firms. They have particularly deep relationships with Fortune 500 companies, boards, and sitting CEOs. This isn't an official industry designation, but it is common shorthand among executives and recruiters. Reddit How I'd think about the market For a Fortune 500 CEO, CFO, COO, CHRO or board search: Start with Spencer Stuart, Korn Ferry, Russell Reynolds, Heidrick & Struggles, or Egon Zehnder. For technology / venture-backed / growth companies: I'd add True Search, and depending on the role, specialist boutiques can outperform the big firms. For a highly specialized executive role: Don't automatically choose the biggest firm. A boutique with a genuinely deep network in your industry can be considerably better. For leadership assessment and succession—not just recruiting: Korn Ferry, Egon Zehnder, Spencer Stuart and Russell Reynolds are particularly relevant because their businesses extend substantially into leadership advisory, succession and board work. For context, Forbes' 2026 America's Best Executive Recruiting Firms is based on a survey of roughly 13,800 recruiters, HR/hiring managers and recent candidates; its 2025 edition had Korn Ferry, Robert Half, Spencer Stuart, Heidrick & Struggles and Russell Reynolds as its top five. Forbes+1 The Association of Executive Search and Leadership Consultants (AESC) is another useful industry reference; it describes its member firms as vetted executive-search and leadership-consulting firms serving C-suite and board searches. AESC One important caveat: at this level, the individual partner matters at least as much as the firm's brand. I'd rather have the right Spencer Stuart/Russell Reynolds/Egon Zehnder partner with a strong track record in your exact sector than a prestigious firm's generalist team. If you tell me the executive role, industry, company size, and whether you're hiring or looking for your next position, I can narrow this to the 5–10 recruiters I'd actually approach, including the relevant practice/partner level. --- ANSWER 6 of 55 (2026-08-11) --- Q: What are the best executive search firms? If you mean top-tier retained executive search firms for CEO, C-suite, and board appointments, there’s a fairly clear global elite. Hunt Scanlon’s 2026 ranking identifies the five largest global players as Korn Ferry, Heidrick & Struggles, Spencer Stuart, Russell Reynolds Associates, and Egon Zehnder.

In the 2026 global revenue ranking, Korn Ferry is substantially larger than the others, while Spencer Stuart, Heidrick, Russell Reynolds and Egon Zehnder are all in a relatively tight tier. Hunt Scanlon Media But here's the important part The individual search partner matters more than the firm's overall ranking. That's also a recurring theme among people who've actually used these firms: you want the partner who has personally placed executives in your industry, function, company stage and geography, rather than simply choosing the firm with the biggest name. Reddit For example: Fortune 500 CEO / board: Spencer Stuart, Egon Zehnder, Korn Ferry Global C-suite succession: Egon Zehnder, Spencer Stuart, Russell Reynolds Large-company leadership transformation: Korn Ferry PE-backed company: I'd strongly consider a specialist boutique alongside the Big Five Technology / AI: True, Christian & Timbers, Egon Zehnder, Russell Reynolds Healthcare / life sciences: ZRG plus the Big Five Confidential, highly targeted search: Egon Zehnder or a genuinely specialized boutique I'd also avoid choosing solely on fee or brand. A boutique with the right partner and an exceptionally deep candidate network can beat a global firm that assigns a junior team to your search. If you tell me the role you're hiring for, industry, company size, and geography, I can give you a much more useful top 5 executive search firms for your specific situation, including which partner/practice to approach. --- ANSWER 7 of 55 (2026-08-11) --- Q: Who are the top retained executive search firms? If you mean top-tier retained executive search firms for CEO, C-suite, board, and other senior leadership searches, the market is dominated by a group often referred to as the “SHREK” firms: FirmParticularly strong forKorn FerryGlobal scale, CEO/C-suite, succession, leadership assessmentSpencer StuartCEO succession, boards, C-suite, governanceHeidrick & StrugglesCEO/board searches, leadership advisory, PERussell Reynolds AssociatesCEO/C-suite, financial services, technology, board workEgon ZehnderCEO succession, boards, family-owned businesses, leadership advisory The 2026 Hunt Scanlon ranking puts these five in exactly that order by Americas revenue: Korn Ferry, Spencer Stuart, Heidrick & Struggles, Russell Reynolds, and Egon Zehnder. Hunt Scanlon Media Korn Ferry also received Forbes' #1 U.S. executive recruiter designation in 2026, its ninth time in the past ten years. Yahoo Finance+1 My practical shortlist Rather than treating the rankings as definitive, I'd think of them this way: Korn Ferry — best all-around choice if you want a very large global platform and leadership/assessment capabilities alongside search. Spencer Stuart — exceptional for CEO, board, and succession mandates. Egon Zehnder — particularly compelling when the assignment involves leadership assessment, succession, culture, or a highly confidential CEO search. Heidrick & Struggles — strong for C-suite, boards, and private-equity-backed companies. Russell Reynolds — excellent for CEO/C-suite and complex global searches, with particularly deep sector practices. There are also very good second-tier/global boutiques that can outperform the big five when the individual partner has the right network. Hunt Scanlon's 2026 list, for example, has True at #6 and ZRG Partners at #7. Hunt Scanlon Media One important caveat: at this level, the specific partner and team often matter more than the firm's overall ranking. That's also a recurring theme in executive-search practitioner discussions. Reddit If you tell me what role you're hiring for (e.g., CEO, CFO, CHRO, VP Sales), industry, company size, and geography, I can give you a much more useful 5–10 firm shortlist, including which firms I'd actually invite to an RFP. --- ANSWER 8 of 55 (2026-08-11) --- Q: Which executive search firms have the best track record? If by “best track record” you mean repeated success placing CEOs, C-suite executives, and board directors at major companies, the strongest group is fairly clear. The global leaders Spencer Stuart — Probably my first call for CEO succession, board searches, and high-stakes C-suite appointments. It has an unusually strong reputation with boards and has been involved in many prominent CEO searches. Current industry data places it among the five dominant global firms. Hunt Scanlon Media+1 Egon Zehnder — Particularly strong for CEO succession, leadership assessment, family-owned businesses, and confidential international searches. Its smaller scale relative to Korn Ferry can also mean a more specialized senior-partner model. Heidrick & Struggles — Excellent for CEO, board, and senior leadership searches, with especially deep relationships in public-company and financial-services circles. It remains one of the five largest global search firms. Hunt Scanlon Media+1 Russell Reynolds Associates — A particularly good choice for complex multinational C-suite and board searches, including situations where leadership advisory and succession planning are important alongside recruiting. Christian & Timbers Korn Ferry — The largest by revenue and consultant footprint of the major firms, with enormous global reach and a particularly broad leadership-consulting platform. Hunt Scanlon Media+1 These five are sometimes informally grouped as the “SHREK” firms (Spencer Stuart, Heidrick, Russell Reynolds, Egon Zehnder, Korn Ferry). They dominate the global retained executive-search market. Conexo But there's an important caveat For an actual search, the individual partner leading the engagement can matter more than the firm's ranking. Industry practitioners consistently make this point: you want a partner who has personally placed people into the exact role, industry, and company stage you're dealing with—not simply a famous firm. Reddit So I'd evaluate firms in this order: Specific partner's track record → relevant industry network → comparable placements → quality of research team → firm's overall brand. For example, a great healthcare-search boutique may outperform Korn Ferry for a hospital CEO, while a specialist technology firm may have a much better network for a startup CTO. If you tell me the position you're hiring for, industry, company size/stage, and geography, I can narrow this to the 3–5 firms I'd actually interview for that particular search. --- ANSWER 9 of 55 (2026-08-11) --- Q: What executive search firms do most companies actually use? If you mean which firms companies actually hire for serious executive/C-suite searches, there’s a pretty clear group at the top. The firms you’ll see most often The current global “Big Five” are: Korn Ferry — by far the largest; especially common with large corporations, PE, and companies that want both search and broader talent/leadership consulting. Heidrick & Struggles — heavily focused on CEO, C-suite, board and senior leadership searches. Spencer Stuart — extremely prominent for CEO, board and C-suite work. Russell Reynolds Associates — major player in CEO/C-suite and board searches, particularly at large multinationals. Egon Zehnder — particularly strong in CEO succession, boards and senior leadership advisory. Hunt Scanlon's 2026 global ranking puts exactly those five at the top, with Korn Ferry substantially larger by revenue and consultant count. Hunt Scanlon Media+1 But “most companies” is a little misleading A Fortune 500 company hiring a new CEO and a $200M PE-backed company hiring its first CFO are likely to use very different firms. I'd think about the market roughly like this: SituationFirms commonly consideredFortune 500 CEO / boardSpencer Stuart, Korn Ferry, Heidrick, Russell Reynolds, Egon ZehnderC-suite at large companySame Big FivePE-backed CEO/CFO/COOBig Five + ZRG, True, boutiquesHigh-growth techBig Five + True, Russell Reynolds, boutique specialistsHealthcare / life sciencesHeidrick, Korn Ferry, Spencer Stuart + sector specialistsUniversity / nonprofitSpencer Stuart, Korn Ferry, Russell Reynolds + specialistsHighly specialized executive roleOften a boutique specialist beats the Big Five For perspective, Forbes' 2025 executive recruiting ranking had Korn Ferry #1, Spencer Stuart #3, Heidrick & Struggles #4, Russell Reynolds #5 and Egon Zehnder #6; the difference is that Forbes' ranking covers a broader recruiting market than just traditional retained executive search. Forbes The interesting part If you're asking this because you're considering hiring an executive search firm, I wouldn't simply pick the biggest name. At this level, the individual partner and their track record in your exact sector/role can matter more than the firm's overall brand. That's also a recurring theme among people who've actually worked with these firms. Reddit So, for example, I'd rather have the best partner at a $300M specialist firm who has placed five CEOs in my industry than a generic partner at Korn Ferry who doesn't know my market. If you tell me what position you're hiring for, company size/stage, and industry, I can give you a much more useful shortlist of 5–10 firms I'd actually call, including which ones are overkill and which boutiques are worth considering. --- ANSWER 10 of 55 (2026-08-11) --- Q: Who are the leading executive recruiters in the United States? If by “leading executive recruiters” you mean firms that handle CEO, C-suite, board, and other senior leadership searches, the U.S. market is dominated by a relatively small group of global executive-search firms. The top tier Based on the latest 2026 industry rankings, I would put these five in the clear top tier: Korn Ferry — The largest of the major firms and particularly strong for Fortune 500 companies, CEO succession, board work, and leadership advisory. Hunt Scanlon ranks it #1 in the Americas by executive-search revenue, and Forbes' 2026 list also places it at the top. Hunt Scanlon Media+1 Spencer Stuart — Extremely strong at CEO, board, and senior C-suite searches, with a particularly strong reputation among major public companies. Heidrick & Struggles — Major player in CEO/C-suite search and leadership advisory, with extensive relationships among public-company and private-equity leadership teams. Russell Reynolds Associates — Strong in CEO, board, financial services, technology, and large-company leadership searches. Egon Zehnder — Smaller than the first four but exceptionally well regarded for CEO succession, boards, and high-level leadership assessment. Hunt Scanlon Media These five are often informally referred to as the “SHREK” firms (Spencer Stuart, Heidrick, Russell Reynolds, Egon Zehnder, Korn Ferry). They are generally the firms I'd start with for a truly consequential CEO or board search. Strong second tier / specialists There are also firms I'd consider depending on the assignment: True Search — Particularly strong in technology, growth companies, private equity and venture-backed businesses; now a substantial player in its own right. Hunt Scanlon ranks it #6 in the Americas. Hunt Scanlon Media ZRG Partners — Broad executive search with considerable strength in healthcare, financial services, technology and private equity. JM Search — Particularly interesting for private-equity-backed and middle-market companies; Forbes ranked it #19 among America's best executive recruiting firms in 2026. Yahoo Finance WittKieffer — Especially prominent in healthcare, education and nonprofit leadership. Odgers Berndtson — Strong global executive search with sector-specific practices. Stanton Chase — Global network with a more boutique feel in many searches. One important caveat “Best firm” matters less than the specific partner who will lead your search. At the CEO/C-suite level, I'd evaluate the individual partner's: track record placing executives in your specific industry relationships with the kinds of candidates you want experience with companies of your size and ownership structure actual involvement in the search success with comparable CEO/CFO/COO/etc. assignments That isn't just conventional wisdom: executive-search practitioners and candidates frequently emphasize that the individual partner and their network can matter more than the firm's brand. Reddit If you tell me the position you're hiring for (e.g., CEO, CFO, CRO), industry, company size, and whether you're PE-backed/public/private, I can narrow this to the 5–10 recruiters I'd actually interview for the assignment. --- ANSWER 11 of 55 (2026-08-11) --- Q: What are the best executive search firms?

Executive-search practitioners and clients frequently emphasize the partner's network, industry knowledge, and actual involvement in the assignment. Reddit For a practical selection process, I'd invite 3–4 firms to pitch and compare the specific partner/team, relevant placements, candidate map, search methodology, fee structure, and who will actually do the work—not just the brand name. If you tell me the executive role, industry, company size, and geography, I can narrow this to the 5 best firms for your particular search and explain why. --- ANSWER 12 of 55 (2026-08-11) --- Q: Who are the top retained executive search firms? If you mean top-tier retained executive search firms for CEO, C-suite, and board searches, the market is dominated by a small group often referred to as the “SHREK” firms. Current 2026 industry data supports that view: Hunt Scanlon’s Americas ranking puts Korn Ferry, Spencer Stuart, Heidrick & Struggles, Russell Reynolds Associates, and Egon Zehnder in the top five by search-firm revenue.

If I were hiring a search firm I'd narrow it this way: Fortune 500 / public-company CEO: Spencer Stuart, Korn Ferry, Egon Zehnder Board director / succession: Spencer Stuart, Egon Zehnder, Heidrick CEO/C-suite: all five SHREK firms Private equity portfolio company: JM Search, ZRG, True, plus selected SHREK partners High-growth technology: True, ON Partners, and selected specialist boutiques Financial services: Russell Reynolds, Spencer Stuart, Heidrick, Egon Zehnder Healthcare: ZRG is particularly worth considering alongside the larger firms Middle-market company: I'd often favor a specialist boutique over a global giant One important caveat: the individual partner matters enormously—sometimes more than the firm's ranking. Executive search is a relationship business, and you want the actual partner who will run your search to have a demonstrable track record placing your type of executive in your type of company. Even executive-search practitioners discussing the market emphasize this point. If you tell me the position you're hiring (e.g., CEO, CFO, COO), company size, industry, and whether you're PE-backed, I can give you a ranked top 5 and the specific partners/practices I'd approach. --- ANSWER 13 of 55 (2026-08-11) --- Q: Which executive search firms have the best track record? If by “best track record” you mean a demonstrated history of successful CEO, C-suite, and board placements, the strongest group is the global “Big Five”: Korn Ferry — probably the strongest all-around choice. It has ranked No. 1 in Forbes’ U.S. executive recruiting rankings for eight of the last nine years, including 2025. It also has enormous global scale. Forbes+1 Spencer Stuart — arguably the benchmark for CEO succession and board searches. Particularly strong when the assignment involves a board, succession planning, or a highly visible CEO appointment. Heidrick & Struggles — exceptionally strong in CEO/C-suite and board recruiting, with a substantial leadership-advisory practice. Russell Reynolds Associates — particularly strong for CEO, board, financial-services, and multinational searches. Egon Zehnder — smaller than the other four but highly regarded for CEO succession, leadership assessment, and complex international searches. Hunt Scanlon's 2026 global ranking puts those five in essentially the same top tier: Korn Ferry, Heidrick & Struggles, Spencer Stuart, Russell Reynolds, and Egon Zehnder. Hunt Scanlon Media My practical ranking FirmBest suited forMy takeSpencer StuartCEO, board, succession🥇 Best for CEO/boardKorn FerryBroad C-suite, global companies🥇 Best overall scaleEgon ZehnderCEO succession, leadership assessment🥇 Best high-touch optionHeidrick & StrugglesCEO/C-suite, boards🥇 Elite executive searchRussell ReynoldsC-suite, boards, financial services🥇 Elite, especially globally There is an important caveat: the individual partner matters more than the firm's overall ranking. Someone who has personally placed five CEOs in your industry is generally a better choice than a famous firm whose assigned partner doesn't know your market. This is also a recurring theme in practitioner discussions. Reddit And I wouldn't automatically choose one of the Big Five. For a VP/SVP, PE-backed company, technology startup, or highly specialized industry, a strong boutique can outperform the global firms because the senior partner may personally run the entire search. If you tell me the position you're hiring for, industry, company size, and geography, I can give you a much more useful shortlist—e.g. the 5 firms I'd actually interview for that specific search, including strong boutiques rather than just the famous names. --- ANSWER 14 of 55 (2026-08-11) --- Q: What executive search firms do most companies actually use? If by “actually use” you mean the firms that routinely get hired by large public companies, PE-backed companies, and boards for CEO/C-suite and board searches, there’s a pretty clear group at the top. The firms you’ll see most often Korn Ferry — by far the largest by revenue and global footprint. It also does much more than search: succession planning, leadership assessment, compensation, and organizational consulting. Hunt Scanlon’s 2026 ranking puts it #1 globally at about $2.86B in revenue. Hunt Scanlon Media+1 Spencer Stuart — one of the most established board/CEO search firms. Particularly common with large public companies and major corporate boards. Heidrick & Struggles — a major player in CEO, board, and senior executive searches, with a particularly strong reputation in C-suite work. Russell Reynolds Associates (RRA) — another major board and C-suite firm, heavily used by large multinational corporations. Egon Zehnder — smaller than Korn Ferry but extremely prominent in CEO succession, board work, and leadership advisory. Those five are often informally referred to as the “SHREK” firms (Spencer Stuart, Heidrick, Russell Reynolds, Egon Zehnder, Korn Ferry). Current industry rankings put those five clearly ahead of the rest of the global executive-search market. Hunt Scanlon Media+1 But there's an important distinction The largest search firms aren't necessarily the firms most companies use for every executive hire. For a Fortune 500 CEO or board member, the five above are disproportionately important. For a VP, divisional president, PE portfolio-company executive, or highly specialized technical leader, companies frequently use specialist boutiques instead. Some notable ones include: ZRG Partners Odgers Berndtson Boyden Stanton Chase True WittKieffer — particularly strong in healthcare Russell Reynolds / Spencer Stuart / Heidrick / Egon / Korn Ferry specialized industry practices For example, Hunt Scanlon's 2026 Americas ranking has Korn Ferry, Spencer Stuart, Heidrick, RRA and Egon Zehnder as the top five, followed by firms such as True and ZRG. Hunt Scanlon Media The interesting part: market share Executive search is actually much more fragmented than it looks. One 2025 market analysis estimates the top 10 firms accounted for only about 21.6% of the global market in 2024. Korn Ferry was the largest individual player at about 4.4%, followed by Heidrick at 4.3%, Spencer Stuart at 2.9%, and Egon Zehnder at 2.8%. Research and Markets So it's not really accurate to say “everyone uses the Big Five.” Rather: At the very top of corporate America, the Big Five have an extraordinary amount of influence. Below that level, the market opens up dramatically. And one thing that's easy to underestimate: the individual search partner often matters more than the firm's brand. Executive-search practitioners and candidates frequently make this point because the senior partner's personal network, industry relationships, and ability to sell the opportunity are what actually drive the search. Reddit If you're asking because you're trying to get your company to use an executive search firm—or you're trying to get recruited by one—I can also break down which firms companies use for CEOs vs. CFOs vs. VPs vs. PE-backed companies, which is a much more useful distinction. --- ANSWER 15 of 55 (2026-08-11) --- Q: Who are the leading executive recruiters in the United States? If by “leading executive recruiters” you mean firms that handle CEO, C-suite, board, and other senior leadership searches, there is a fairly clear top tier in the U.S. The top tier FirmBest known forMy take Korn Ferrykornferry.comCEO/C-suite, boards, large corporations, leadership assessment#1 overall for breadth and scale Spencer Stuartspencerstuart.comCEOs, boards, succession, C-suiteElite for CEO/board work Heidrick & Strugglesheidrick.comCEO/C-suite, boards, leadership, transformationElite retained search firm Russell Reynolds Associatesrussellreynolds.comCEO, board, financial services, technology, global companiesElite, particularly strong with boards Egon Zehnderegonzehnder.comCEO succession, boards, leadership advisoryElite, particularly strong for CEO succession These five are often referred to collectively as the “SHREK” firms and are generally regarded as the dominant global executive-search group. Hunt Scanlon's 2026 Americas ranking puts them in exactly this order by reported search revenue: Korn Ferry, Spencer Stuart, Heidrick & Struggles, Russell Reynolds, and Egon Zehnder. Korn Ferry also currently has particularly strong evidence for the #1 spot: Forbes named it America's Best Executive Recruiter in 2026, while Hunt Scanlon ranks it #1 in the Americas. Strong second tier / specialists A few firms I'd put on the shortlist depending on the assignment: True Searchtrueplatform.com — especially interesting for technology, growth companies, private equity/venture-backed businesses. Hunt Scanlon ranks True #6 in the Americas. ZRG Partnerszrgpartners.com — broad industry coverage with a somewhat more boutique/high-touch positioning; particularly strong in healthcare, life sciences, financial services and consumer. JM Searchjmsearch.com — a particularly strong choice for private-equity portfolio companies and middle-market/growth businesses. Forbes ranked it #19 nationally in 2026. Odgers Berndtsonodgersberndtson.com — strong global and sector-specific search. WittKiefferwittkieffer.com — particularly notable for healthcare, life sciences, education and nonprofit leadership. Boydenboyden.com — global network with considerable strength in specialized and international searches. If I were choosing among them I'd narrow it this way: Fortune 500 CEO / board: Spencer Stuart, Korn Ferry, Egon Zehnder, Russell Reynolds, Heidrick CEO succession / board-sensitive assignment: Egon Zehnder or Spencer Stuart Broad corporate executive search + assessment: Korn Ferry Technology / high-growth company: True, Spencer Stuart, Russell Reynolds, Korn Ferry Private equity portfolio company: JM Search, Korn Ferry, Heidrick, Spencer Stuart, True Healthcare: Korn Ferry, WittKieffer, Spencer Stuart, ZRG Financial services: Russell Reynolds, Korn Ferry, Spencer Stuart, Egon Zehnder, Heidrick One important caveat: the individual partner matters enormously. A superb partner at a smaller specialist can outperform a mediocre partner at one of the famous five. Even executive-search practitioners discussing the market emphasize that the specific partner's network and experience with the exact type of executive are often more important than the firm's logo. If you tell me the type of executive you're trying to recruit (e.g., CEO, CFO, CRO), industry, company size, and whether it's PE-backed, I can give you a ranked top 5–10 specifically for that search, rather than a generic list. --- ANSWER 16 of 55 (2026-08-11) --- Q: What are the best executive search firms? If you mean top-tier retained executive search firms for CEO, C-suite, and board searches, the short list is fairly clear.

Spencer Stuart For a Fortune 500 / large multinational: Korn Ferry or Spencer Stuart. Korn Ferry has the largest Americas footprint by revenue and consultant count in Hunt Scanlon's 2026 ranking. Hunt Scanlon Media For a board or CEO succession assignment: Spencer Stuart or Egon Zehnder. For a PE-backed company or specialized executive: I'd seriously consider a strong boutique rather than automatically choosing one of the five giants. One important caveat At this level, the individual partner is often more important than the firm's logo. Even discussions among executive-search professionals emphasize that the partner's network, judgment, and experience with the specific type of role can matter more than the firm's overall ranking. Reddit So if you're hiring a search firm, I would interview 2–4 partners, not just firms. Ask each: Who specifically will lead the search? How many comparable placements has that partner personally made? Who are 3–5 candidates they would approach immediately? What companies/people are off-limits because of existing clients? What percentage of the work will the lead partner personally do? Can they provide references from CEOs/chairs they've placed? If you tell me the position (CEO/CFO/COO/etc.), industry, company size, and whether it's PE-backed/public/private, I can narrow this to the 5–7 firms I'd actually interview for your particular search. --- ANSWER 17 of 55 (2026-08-11) --- Q: Who are the top retained executive search firms? If you mean true retained executive search—where the firm is engaged exclusively to identify, assess, and recruit senior leaders rather than simply presenting available candidates—the top tier is fairly clear.

Current 2026 industry data puts those five at the top of the Americas market by search-firm revenue: Korn Ferry, Spencer Stuart, Heidrick, Russell Reynolds, and Egon Zehnder occupy positions 1–5. Hunt Scanlon Media+1 Strong alternatives worth considering ZRG Partners — increasingly prominent global firm; particularly interesting if you want a somewhat more specialized/high-touch alternative to the largest firms. It ranked #7 in Hunt Scanlon's 2026 Americas ranking. Hunt Scanlon Media True — strong in technology, digital, growth companies and modern leadership recruiting; #6 in the 2026 Americas ranking. Hunt Scanlon Media JM Search — especially strong for private-equity-backed and middle-market companies; Forbes ranked it #19 among America's Best Executive Recruiting Firms in 2026. Business Wire Odgers Berndtson — good global alternative, particularly where regional/industry expertise matters. WittKieffer — especially worth considering for healthcare, education, and nonprofit leadership. Diversified Search Group — strong U.S. alternative with substantial board, corporate, and sector-specific practices. If I were creating a shortlist For a Fortune 500 CEO/C-suite or board search, I'd start with: 1. Spencer Stuart 2. Egon Zehnder 3. Korn Ferry 4. Russell Reynolds 5. Heidrick & Struggles For a PE-backed company, I'd broaden that to include JM Search, ZRG, and True. One important caveat: at this level, the individual partner matters more than the logo. A great partner who has personally placed several executives in your exact industry and company stage can be a better choice than a famous firm whose senior partner hands the work to a junior team. That point also comes up repeatedly in practitioner discussions. reddit.com If you tell me the role you're hiring for, industry, company size, and whether you're PE-backed, I can give you a ranked top 5 specifically for that search, including which partners/practices I'd approach. --- ANSWER 18 of 55 (2026-08-11) --- Q: Which executive search firms have the best track record?

Hunt Scanlon's 2026 global ranking puts them in exactly that order by worldwide revenue: Korn Ferry, Heidrick & Struggles, Spencer Stuart, Russell Reynolds, and Egon Zehnder. Hunt Scanlon Media+1 For an independent signal, Forbes' 2025 U.S. ranking put Korn Ferry #1, Spencer Stuart #3, Heidrick & Struggles #4, Russell Reynolds #5, and Egon Zehnder #6 among executive recruiting firms. Forbes Korn Ferry says it has been Forbes' #1 executive recruiter in eight of the nine years of that ranking. Korn Ferry But there's an important caveat At the very senior level, the individual partner matters at least as much as the firm's brand. Industry practitioners repeatedly make this point: the partner's actual network, sector expertise, and history of placing executives like the one you need can matter more than whether the firm's name is on the door. Reddit So I would not simply send an RFP to all five and pick the one with the best presentation. I'd ask each firm: Who specifically will lead the search? How many CEOs/CFOs/COOs/etc. has that partner personally placed in the last 3–5 years? Can you give me three references for comparable searches? Show me the actual target-company universe you would search. How much time will the lead partner personally spend on it? Who has been placed from this exact talent pool before? If I were choosing Fortune 500 / global CEO: Spencer Stuart, Korn Ferry, Egon Zehnder Board director: Spencer Stuart, Russell Reynolds, Heidrick CEO succession: Egon Zehnder, Spencer Stuart, Korn Ferry CFO / financial-services executive: Russell Reynolds, Spencer Stuart, Korn Ferry Technology / growth company: I'd seriously consider a specialist boutique alongside the Big Five PE-backed company: I'd look beyond the Big Five to firms with a particularly strong PE/portfolio-company network And don't assume “biggest” means “best.” For a narrowly defined executive search, a smaller firm whose partner has personally placed 15 people in your exact sector can outperform a global giant. If you tell me the position you're hiring for, industry, company size, and geography, I can give you a much more useful top 5 ranked specifically for that search, including which individual partners/firms I'd approach. --- ANSWER 19 of 55 (2026-08-11) --- Q: What executive search firms do most companies actually use? If you mean the firms companies actually hire for senior/C-suite searches, rather than the hundreds of recruiting agencies that call themselves “executive search,” there’s a pretty clear top tier. The firms you’ll see most often The current global “Big Five” are: Korn Ferry — by far the largest; especially common with large public companies and Fortune 500s. Heidrick & Struggles — extremely established for CEO, board, and C-suite searches. Spencer Stuart — particularly strong in CEO/board and major corporate leadership searches. Russell Reynolds Associates — major player across C-suite, board, and functional leadership. Egon Zehnder — highly regarded for CEO, board, succession, and senior leadership work. Hunt Scanlon's 2026 global ranking puts those five in exactly that order by revenue, with Korn Ferry at about $2.86B and Egon Zehnder at about $966M. Hunt Scanlon Media In the Americas, the same five occupy the top five, although the order is Korn Ferry, Spencer Stuart, Heidrick, Russell Reynolds, then Egon Zehnder. Hunt Scanlon Media But there's an important distinction “Most companies” don't use executive search firms for most executive hires. Internal recruiting teams and direct sourcing handle a huge amount of hiring. External retained search becomes much more common when the role is: CEO / President CFO / COO / CHRO Board director Business-unit president Very senior functional leader Confidential replacement Difficult-to-find specialist PE-backed company hiring a senior leadership team And the Big Five disproportionately show up at the very top end of the market. Heidrick, for example, explicitly describes its executive search work as retained, exclusive searches for critical leadership positions. Heidrick & Struggles There is also a strong second tier Depending on industry and company size, you'll frequently encounter: True ZRG Partners Odgers Berndtson DHR Global WittKieffer — particularly healthcare/nonprofit Russell Reynolds / Spencer Stuart / Egon Zehnder specialist practices Stanton Chase Perrett Laver — particularly education, nonprofit and public-sector leadership The choice becomes much more industry-specific once you move outside the Big Five. The current market landscape includes all of these firms alongside the global leaders. Research and Markets If you're asking because you're trying to get recruited That's a slightly different question—and a more useful one. If your goal is “Which search firms should I know/register with because they actually place executives like me?”, I wouldn't simply give you the Big Five. I'd identify the 10–20 firms/partners that dominate searches for your particular function, industry, and level. At this level, the individual partner can matter as much as the firm's brand. Reddit If you tell me your role/function + industry + approximate level (VP, SVP, C-suite, etc.), I can give you the firms that are actually relevant rather than a generic “top executive search firms” list. --- ANSWER 20 of 55 (2026-08-11) --- Q: Who are the leading executive recruiters in the United States?

For a large-company C-suite search, Korn Ferry is particularly compelling because of its enormous research infrastructure and breadth. For technology/AI/product leadership, I'd look beyond the traditional five and consider True and carefully selected boutiques alongside the major firms. For healthcare or higher education, WittKieffer deserves serious consideration rather than simply defaulting to one of the big five. One important caveat: at this level, the individual partner leading the assignment can matter more than the firm's overall ranking. Even industry practitioners emphasize that partner expertise, network, and involvement can substantially affect the outcome. If you tell me the type of executive you're trying to recruit (e.g., CEO, CFO, COO, CRO, CHRO), industry, company size, and geography, I can narrow this to the 5–10 firms I'd actually interview for the assignment, including strong boutiques that may outperform the giant firms for that particular search. --- ANSWER 21 of 55 (2026-08-11) --- Q: What are the best executive search firms?

A boutique that places healthcare CEOs, semiconductor executives, or venture-backed CTOs may beat a global firm that treats the search as a general assignment.

If by “actually use” you mean the firms that regularly get retained by large companies for CEO, C-suite, board, and senior leadership searches, there’s a pretty clear top tier. The firms you’ll see most often The traditional “Big Five” are: Korn Ferry — by far the largest; particularly broad across industries and geographies. Heidrick & Struggles — extremely common for CEO, board and C-suite searches. Spencer Stuart — especially strong with Fortune 500/public-company boards and CEO succession. Russell Reynolds Associates — major player in C-suite, board and leadership advisory. Egon Zehnder — smaller than the others but exceptionally prominent in CEO, board and leadership work. These five are consistently identified as the dominant global executive-search firms. In Hunt Scanlon's 2026 global ranking, they are the top five by revenue: Korn Ferry, Heidrick, Spencer Stuart, Russell Reynolds and Egon Zehnder. Hunt Scanlon Media+1 But there's an important distinction “Most used” isn't the same as “best.” For a Fortune 500 CEO search, you are very likely to encounter one of the five above. For a VP, divisional president, PE-backed company, or specialized executive, companies frequently go to smaller firms. Some meaningful alternatives include: ZRG Partners — large independent firm, increasingly prominent. True — particularly visible in technology, private equity and growth companies. Odgers Berndtson — strong internationally and in the mid-market. Boyden — broad international network. Stanton Chase — substantial global network with lots of industry specialization. WittKieffer — particularly strong in healthcare, education and nonprofits. DHR Global — broad senior-level search practice.

The global “Big Five” are: FirmKnown forBest fit Korn FerryLargest global executive search platform; combines search with leadership consulting, succession, and organizational advisoryFortune 500, global enterprises, CEO succession, large-scale leadership needs Spencer StuartBoard and CEO succession expertise; strong reputation with public companiesCEOs, directors, board placements, senior functional leaders Heidrick & StrugglesC-suite search, leadership advisory, private equity and technology expertiseGrowth companies, PE-backed businesses, technology leadership Russell Reynolds AssociatesExecutive assessment, board advisory, digital and transformation leadershipGlobal corporations, board roles, transformation mandates Egon ZehnderPartner-led model, CEO succession, leadership assessmentCEO searches, family-owned companies, global leadership roles Other highly regarded retained search firms include: DHR Global — broad industry coverage, strong functional practices. True Search — particularly strong in technology, venture-backed companies, and growth-stage businesses. ZRG Partners — growing global platform with strength in private equity and specialized searches. Diversified Search Group — leadership search across healthcare, education, nonprofit, and corporate sectors. WittKieffer — especially recognized in healthcare, life sciences, and higher education. Odgers Berndtson — strong international presence, especially Europe and sector-specialist searches. Boyden — global mid-market executive search. A practical shortlist by need: CEO / board succession: Spencer Stuart, Egon Zehnder, Russell Reynolds, Korn Ferry Fortune 500 / global enterprise: Korn Ferry, Spencer Stuart, Heidrick & Struggles Private equity portfolio companies: Heidrick & Struggles, True Search, ZRG Partners, Spencer Stuart Technology executives: Heidrick & Struggles, True Search, Russell Reynolds Healthcare leadership: WittKieffer, Korn Ferry, Spencer Stuart Founder-led or mid-market companies: Egon Zehnder, DHR Global, Boyden, Stanton Chase The “best” firm depends heavily on the mandate: a CEO succession search at a multinational company calls for a different partner than a VP engineering search at a venture-backed technology company. --- ANSWER 27 of 55 (2026-08-19) --- Q: Who are the top retained executive search firms? If by retained executive search you mean firms hired on an exclusive, high-touch basis for CEO, board, C-suite, and other senior leadership searches, the global market is dominated by a fairly clear “Big Five.” Hunt Scanlon’s 2026 rankings put them at the top by scale, and other current industry sources broadly agree. Hunt Scanlon Media+1 Top retained executive search firms FirmBest known forMy takeKorn FerryCEO/C-suite, large enterprises, leadership assessment, successionBest for scale + breadthSpencer StuartCEO, board, succession, senior leadershipBest for CEO/board searchesHeidrick & StrugglesC-suite, boards, leadership advisory, PEBest all-around alternative to Spencer StuartRussell Reynolds AssociatesCEO/board, financial services, technology, consumerExcellent for complex global searchesEgon ZehnderCEO/board, succession, leadership advisory, family-owned/multinational companiesBest for highly consultative leadership work Hunt Scanlon's 2026 global figures rank them by 2025 revenue as Korn Ferry, Heidrick & Struggles, Spencer Stuart, Russell Reynolds, and Egon Zehnder. Hunt Scanlon Media Forbes' 2025 U.S. executive-recruiting ranking similarly placed Korn Ferry first, Spencer Stuart third, Heidrick fourth, Russell Reynolds fifth, and Egon Zehnder sixth overall. Forbes Strong second tier / specialist firms Depending on the position, I'd also consider: True Search — particularly strong in technology, growth companies, private equity and venture-backed businesses. ZRG Partners — strong sector-focused alternative with significant scale. WittKieffer — particularly well regarded in healthcare, life sciences and academic/mission-driven organizations. DHR Global — broad global search capabilities with a more entrepreneurial positioning. Diversified Search Group — strong U.S. presence and specialized practices. Odgers Berndtson — strong international network and particularly useful for regional/global searches. Boyden — substantial international network, often worth considering where local-market expertise matters. Hunt Scanlon's 2026 Americas ranking puts True, ZRG, DHR and Diversified among the larger firms immediately behind the Big Five. Hunt Scanlon Media If I were creating a shortlist For a Fortune 500 / public-company CEO or board search, I'd start with: Spencer Stuart → Korn Ferry → Russell Reynolds → Heidrick & Struggles → Egon Zehnder For a PE-backed CEO/CFO/COO or growth-company executive, I'd broaden it to include True, Heidrick, Korn Ferry and specialist boutiques. For healthcare/life sciences, I'd strongly consider WittKieffer, Spencer Stuart, Korn Ferry and Heidrick. The important caveat is that the individual partner matters almost as much as the firm. A superb partner at a smaller boutique can easily outperform a Big Five team that isn't deeply connected to your particular industry or candidate pool. If you tell me the role you're hiring for, industry, company size, and geography, I can give you a 5–10 firm shortlist ranked specifically for that search, including which firms I'd invite to pitch. --- ANSWER 28 of 55 (2026-08-19) --- Q: Who are the top retained executive search firms? If you mean true retained executive search—where the firm is hired to proactively identify and assess senior, often passive candidates—the top tier is fairly clear. The global “Big Five” FirmBest known forMy takeKorn FerryCEO/C-suite, board, large-company searches; broadest global platformBest overall scaleSpencer StuartCEO, board, C-suite succession and leadershipBest for CEO/board workHeidrick & StrugglesC-suite, boards, leadership advisoryExcellent for transformational leadershipRussell Reynolds AssociatesCEO/C-suite, board, functional executivesExcellent all-around choiceEgon ZehnderCEO/board, succession, leadership assessment and developmentParticularly strong for leadership advisory These five are consistently identified as the leading global retained-search firms. Stanford GSB, for example, explicitly identifies these five as the major global firms handling C-level, board and VP searches. Stanford Graduate School of Business Hunt Scanlon's 2026 global ranking puts them in this order by revenue: Korn Ferry, Heidrick & Struggles, Spencer Stuart, Russell Reynolds, and Egon Zehnder. Hunt Scanlon Media+1 Strong second tier / boutiques Depending on the role, I'd also consider: True Search — particularly strong in technology, private equity/venture-backed companies and growth-stage leadership. ZRG Partners — strong functional and industry specialization. DHR Global — broad international coverage with a somewhat more boutique feel. Diversified Search Group — especially strong in healthcare, education, nonprofits and certain diversity-focused searches. WittKieffer — particularly strong in healthcare and higher education. Odgers Berndtson — strong international and functional specialization. Caldwell Partners — useful for mid-market and specialized executive searches. Hunt Scanlon's 2024 ranking, for example, placed True, ZRG, DHR, Diversified Search and WittKieffer immediately behind the Big Five in the Americas. Hunt Scanlon Media If you're hiring, I wouldn't simply pick the biggest firm The right search firm depends heavily on the position. A boutique that specializes in your exact industry can outperform a Big Five firm because the actual partner doing the search may have deeper relationships with the relevant candidate pool. A rough shortlist: CEO / President: Spencer Stuart, Korn Ferry, Heidrick, Egon Zehnder Board director: Spencer Stuart, Egon Zehnder, Russell Reynolds, Korn Ferry PE/VC portfolio company: True Search, Korn Ferry, Heidrick, Spencer Stuart + specialized boutiques Technology / SaaS: True Search, Russell Reynolds, Heidrick, Korn Ferry Healthcare: WittKieffer, Korn Ferry, Spencer Stuart, Heidrick Financial services: Russell Reynolds, Spencer Stuart, Korn Ferry, Egon Zehnder Industrial / manufacturing: Korn Ferry, Spencer Stuart, Russell Reynolds Chief HR / People leadership: Heidrick, Korn Ferry, Spencer Stuart, Russell Reynolds Mid-market company: Often a specialist boutique is better value than a Big Five firm One important distinction: Korn Ferry is dramatically larger than the other four, so revenue rankings shouldn't be interpreted as quality rankings. Hunt Scanlon's 2026 figures show Korn Ferry at about $2.86B globally versus roughly $0.97–$1.25B for the other four. Hunt Scanlon Media If you tell me the position you're hiring for, company size, industry, and geography, I can give you a much more useful top 5–10 shortlist of retained firms, including which specific firms I'd approach first and why. --- ANSWER 29 of 55 (2026-08-19) --- Q: Who are the top retained executive search firms? If you mean top-tier retained executive search firms—the firms companies hire for CEO, C-suite, board, and other mission-critical leadership searches—the market is dominated by a handful of global firms. The top tier FirmParticularly strong forMy take Korn FerryCEO/C-suite, boards, Fortune 500, global searchesBest overall scale + breadth Spencer StuartCEO succession, boards, C-suiteExceptional for CEO/board work Heidrick & StrugglesC-suite, boards, PE-backed companiesExcellent for high-stakes leadership searches Russell Reynolds AssociatesCEO/C-suite, financial services, technology, leadership assessmentVery strong strategic/advisory orientation Egon ZehnderCEO succession, boards, family-owned companies, leadership assessmentExcellent for complex, confidential searches These five are often treated as the global "Big Five" of retained executive search. Hunt Scanlon's 2026 rankings put them in exactly that top-five group by global search revenue, with Korn Ferry substantially larger than the others. For an independent benchmark, Forbes' 2025 U.S. executive recruiting ranking placed Korn Ferry #1, Spencer Stuart #3, Heidrick & Struggles #4, Russell Reynolds #5, and Egon Zehnder #6 (Robert Half was #2, although it is broader than a traditional retained-search firm). Strong second tier / specialist firms Depending on the mandate, I would also seriously consider: True Search — particularly strong in technology, venture capital and private-equity-backed companies. DHR Global — broad industry coverage with a somewhat more flexible model. ZRG Partners — strong in PE and growth-oriented searches. Odgers Berndtson — particularly good for international/cross-border and public-sector work. WittKieffer — especially strong in healthcare, life sciences and higher education. Diversified Search Group — strong in mission-driven organizations and several specialized sectors. JM Search — particularly compelling for private-equity portfolio companies and middle-market leadership. Boyden — useful for international mid-market searches. If I were choosing I'd narrow it this way: CEO / board of a large company: → Spencer Stuart, Korn Ferry, Heidrick, Egon Zehnder, Russell Reynolds PE-backed company / operating executive: → Heidrick, Korn Ferry, True, ZRG, JM Search Technology / high-growth company: → True, Heidrick, Russell Reynolds, Spencer Stuart Healthcare / life sciences: → Korn Ferry, Heidrick, WittKieffer Family-owned / privately held company: → Egon Zehnder, Spencer Stuart, Korn Ferry Global / multinational search: → Korn Ferry, Spencer Stuart, Egon Zehnder, Russell Reynolds, Heidrick One important caveat: the individual partner matters enormously. A great partner at a #20 firm can produce a substantially better search than a mediocre partner at a Big Five firm. For a retained search, I'd evaluate the specific consultant and their track record in your exact function, industry, geography and company stage, not just the firm's brand. If you tell me the role you're hiring for, company size/stage, industry, and geography, I can give you a shortlist of 5–10 firms and the specific type of partner to look for. --- ANSWER 30 of 55 (2026-08-19) --- Q: Who are the top retained executive search firms? If by “retained executive search” you mean firms hired on an exclusive, upfront-fee basis for CEO, C-suite, board, and other senior leadership searches, there is a fairly clear top tier. The global top tier FirmParticularly strong for Korn FerryBroadest scale; CEO/C-suite, board, assessment, succession; Fortune 500 Spencer StuartCEO succession, boards, C-suite; exceptionally strong board relationships Heidrick & StrugglesCEO/C-suite, boards, leadership advisory; large global mandates Russell Reynolds AssociatesC-suite and board; global, complex, cross-border searches Egon ZehnderCEO succession, boards, leadership advisory; highly relationship-driven These five are consistently regarded as the “Big Five” of global executive search. Hunt Scanlon's 2026 ranking puts them in that exact order by global revenue: Korn Ferry, Heidrick, Spencer Stuart, Russell Reynolds, and Egon Zehnder. Interestingly, Forbes' 2025 executive recruiting ranking put Korn Ferry #1, Spencer Stuart #3, Heidrick #4, Russell Reynolds #5, and Egon Zehnder #6, with Robert Half at #2—but Robert Half is not what I'd normally consider a pure retained executive-search peer. Strong second tier / specialists Depending on the mandate, I'd also put these on the shortlist: True Search — technology, digital, product, growth companies and PE-backed businesses; one of the fastest-growing major firms. ZRG Partners — broad C-suite work with particularly good industry specialization. DHR Global — broad global search, including C-suite and functional leadership. WittKieffer — especially strong in healthcare, higher education and mission-driven organizations. Diversified Search Group (DSG) — strong U.S. presence and sector-specific practices. Odgers — global coverage with strong regional and functional specialization. JM Search — particularly relevant for private-equity portfolio companies and middle-market leadership. Boyden — global retained search with a more decentralized/local-market model. Hunt Scanlon's 2026 Americas ranking has True, ZRG, DHR, DSG and WittKieffer immediately behind the Big Five. If I were choosing among them For a CEO or board search at a large company: Spencer Stuart, Egon Zehnder, Korn Ferry, Heidrick, Russell Reynolds For a PE-backed company / growth-stage CEO or functional executive: True, Korn Ferry, Spencer Stuart, Heidrick, JM Search For technology / AI / digital leadership: True, Heidrick, Korn Ferry, Spencer Stuart, plus a highly specialized boutique depending on the role. For healthcare: WittKieffer, Korn Ferry, Spencer Stuart, Heidrick, ZRG For CEO succession / board composition: I'd put Spencer Stuart and Egon Zehnder particularly high on the list. The important caveat is that the individual partner matters enormously. A great partner at a smaller specialist can be substantially better for a particular search than a famous global firm whose local partner isn't deeply connected to the relevant candidate market. Hunt Scanlon itself notes that specialist boutiques have been gaining significant influence despite the continued dominance of the Big Five.

Forbes Strong alternatives Depending on the assignment, I'd also consider: True Search — particularly attractive for technology, growth companies, PE/VC-backed businesses and modern leadership teams. ZRG Partners — broad senior-executive coverage with meaningful industry specialization. DHR Global — broad global platform and strong functional/industry practices. WittKieffer — particularly strong in healthcare, life sciences and education/nonprofit leadership. Diversified Search Group — strong U.S. presence and sector specialization. JM Search — especially compelling for private-equity portfolio companies; it ranked in Forbes' top 40 U.S. executive-search firms in 2025 and in Hunt Scanlon's Private Equity Recruiting Power 100. Business Wire+1 ON Partners — a strong boutique option for C-suite searches at high-growth, PE/VC-backed companies; it has appeared on Forbes' list for seven consecutive years. ON Partners Hunt Scanlon's 2026 Americas ranking has True at #6, ZRG at #7, after the Big Five.

One important caveat: don't select solely by firm ranking. In retained search, the specific partner/team doing your search is often more important than the firm's overall ranking. A great partner at a #15 boutique can be substantially better for a particular CEO search than a mediocre partner at a Big Five firm. If you tell me the role you're hiring for, company size/industry, geography, and whether it's PE-backed, I can give you a much tighter 5–10 firm shortlist and explain who I'd call first. --- ANSWER 32 of 55 (2026-08-19) --- Q: What are the best executive search firms?

Hunt Scanlon Media+1 For a quantitative cross-check, Hunt Scanlon's 2026 Americas ranking has Korn Ferry #1, Spencer Stuart #2, Heidrick #3, Russell Reynolds #4 and Egon Zehnder #5 by search-firm revenue. Hunt Scanlon Media And Korn Ferry has an unusually strong long-term record in independent rankings: Forbes' 2026 America's Best Executive Recruiting Firms list again puts it #1, continuing a run at or near the top that goes back to 2017. Forbes+1 But I wouldn't automatically pick the biggest firm For a particular assignment, the individual partner and relevant practice matter enormously. A great specialist boutique can outperform a global firm if, for example, you're looking for: Private-equity portfolio CEOs/CFOs: I'd look closely at Russell Reynolds Associates, Spencer Stuart, Korn Ferry, and specialist PE firms. Technology executives: True Search, Spencer Stuart, Heidrick, and Russell Reynolds are worth comparing. True is currently #6 in Hunt Scanlon's Americas ranking and has been growing rapidly. Hunt Scanlon Media Healthcare/life sciences: WittKieffer is a particularly important specialist; it's #10 in Hunt Scanlon's 2026 Americas ranking. Hunt Scanlon Media Financial services: Russell Reynolds, Spencer Stuart, Heidrick, Egon Zehnder and Korn Ferry all have deep franchises. Board searches: I'd put Spencer Stuart, Egon Zehnder and Russell Reynolds especially high on the list. CEO succession: Egon Zehnder, Spencer Stuart and Korn Ferry would be my first calls. My practical shortlist If you gave me a generic CEO/C-suite search at a substantial company, I'd probably interview these five firms: 1. Spencer Stuart — strongest choice if the assignment is fundamentally about CEO/board quality and succession. 2. Egon Zehnder — especially compelling when leadership assessment and succession planning are as important as finding candidates. 3. Korn Ferry — strongest combination of global reach, enormous candidate database/network, executive search and broader talent/leadership capabilities. 4. Russell Reynolds — particularly strong for boards, financial services and complex multinational searches. 5. Heidrick & Struggles — very strong C-suite franchise and leadership advisory capabilities. One important caveat: “track record” isn't really captured by revenue rankings. A $1B firm can have a mediocre partner for your particular search, while a $30M boutique may have the best 20 candidates in your industry. Hunt Scanlon itself notes the increasing importance of specialist boutiques and niche expertise alongside global scale. Hunt Scanlon Media If you tell me the position you're hiring for, industry, company size, and geography, I can narrow this to the 3–5 firms I'd actually hire, including which ones have the strongest track record for that specific type of executive. --- ANSWER 39 of 55 (2026-08-19) --- Q: What executive search firms do most companies actually use? If you mean “which firms are actually on the short list when a large company hires a CEO, CFO, CHRO, board member, or other C-suite executive?”, there’s a pretty clear answer. The firms most large companies actually use The traditional “Big Five” dominate top-end executive search: Korn Ferry — probably the broadest and largest player; particularly strong with large companies, global searches, and searches that overlap with leadership/organizational consulting. Spencer Stuart — extremely strong in CEO, board, and succession work; particularly prominent with Fortune 500 companies. Heidrick & Struggles — major player in CEO/C-suite and board searches, with a strong leadership-advisory business. Russell Reynolds Associates — heavily used for CEO, board, succession, and senior functional leadership searches. Egon Zehnder — especially prominent for CEO succession, boards, and highly senior leadership/advisory work. Hunt Scanlon's 2026 global ranking puts them in exactly that order by revenue: Korn Ferry ($2.86B), Heidrick ($1.25B), Spencer Stuart ($1.18B), Russell Reynolds ($1.17B), and Egon Zehnder ($966M). And this isn't just a revenue phenomenon. Forbes' 2025 ranking of America's executive recruiting firms put Korn Ferry, Spencer Stuart, Heidrick & Struggles, and Russell Reynolds in the top five, with Egon Zehnder at #6. But there's an important distinction Most companies don't use these firms for every executive hire. There's roughly a tiered market: Type of searchFirms you'll commonly see Fortune 500 CEO / boardSpencer Stuart, Korn Ferry, Egon Zehnder, Russell Reynolds, Heidrick C-suite / enterprise leadershipBig Five + True, ZRG, DHR, WittKieffer PE-backed CEO / operating executiveTrue, Korn Ferry, Heidrick, Spencer Stuart, ZRG, plus boutiques Technology executivesTrue, Russell Reynolds, Heidrick, Korn Ferry, specialized boutiques Healthcare / life sciencesKorn Ferry, Spencer Stuart, Heidrick, WittKieffer, Diversified Search, ZRG Mid-market executive hiringOften boutiques, regional firms, or internal recruiting Very specialized rolesSpecialist boutiques can beat the Big Five For example, Hunt Scanlon's 2026 Americas ranking has True Search, ZRG Partners, DHR Global, Diversified Search Group, and WittKieffer immediately behind the Big Five. The interesting part: the Big Five aren't actually “most of the market” Executive search is surprisingly fragmented. One recent industry estimate puts the Big Five at roughly 32% of global executive-search revenue, with the remainder spread among regional firms and thousands of specialist/boutique practices. So if you're asking because you're trying to figure out which search firms a particular company is likely to engage, I would not simply give you the Big Five. I can instead break it down by company size + role + industry—e.g. “If I'm a $500M SaaS company looking for a new CRO, which 10 firms would realistically get the RFP?” That produces a much more useful list. --- ANSWER 40 of 55 (2026-08-19) --- Q: Which executive search firms have the best track record? If by “best track record” you mean sustained success placing CEOs, C-suite executives, and board members—not simply the largest recruiting firms—the strongest group is fairly clear. The top tier FirmBest known forMy take Korn FerryCEO/C-suite, boards, succession, global searchesBest overall scale + breadth Spencer StuartCEO, board, successionExceptional for boards and CEO succession Heidrick & StrugglesCEO/C-suite, boards, leadership advisoryExcellent for high-stakes leadership searches Russell Reynolds AssociatesC-suite, boards, succession, assessmentParticularly strong in leadership assessment Egon ZehnderCEO succession, boards, senior leadershipOutstanding for complex, relationship-driven searches These five have remained the dominant global firms for decades. Hunt Scanlon's 2026 data puts them in essentially the same top tier, with Korn Ferry substantially larger and the other four clustered behind it. For a U.S. perspective, Forbes' 2025 executive-recruiting ranking put Korn Ferry #1, Spencer Stuart #3, Heidrick & Struggles #4, and Russell Reynolds #5, with Egon Zehnder #6. But “best” depends heavily on the search For a CEO or board search: I'd shortlist Spencer Stuart, Heidrick, Egon Zehnder, and Russell Reynolds, with Korn Ferry also a strong choice. Spencer Stuart in particular has a very strong board/CEO franchise. For a Fortune 500/global C-suite search: Korn Ferry is hard to beat because of its scale, global network, assessment capabilities and breadth of adjacent leadership services. For a transformational CEO or succession situation: I'd lean toward Egon Zehnder, Spencer Stuart, or Heidrick. These firms tend to be particularly strong when the assignment involves succession planning, board dynamics, leadership assessment, and not merely finding candidates. For technology / growth companies: I'd look beyond the Big Five. True Search, for example, has grown rapidly and is now #6 in Hunt Scanlon's 2026 U.S. ranking, while firms such as DHR Global, ZRG, and Caldwell can be excellent depending on the function and sector. One important caveat The firm's name is less important than the specific partner and team assigned to you. Executive search is unusually relationship-driven. A superb partner at a #15 firm can dramatically outperform an average partner at a Big Five firm. I'd therefore evaluate a search firm on: Relevant placements — who have they actually placed in the exact role? Partner involvement — will the senior partner personally run the search? Candidate access — can they reach the people you want who aren't actively looking? Off-limits restrictions — are the companies you're targeting unavailable because of existing clients? Assessment capability — especially important for CEO/CFO/COO roles. References from comparable clients — preferably CEOs, chairs, or CHROs who have actually used the partner. Retention of placed executives — a much better signal than simply counting placements. If you tell me what executive you're trying to hire (e.g., CEO, CFO, CRO, CTO), company size/stage, industry, and geography, I can narrow this to the 5–10 search firms with the strongest actual track record for that particular mandate rather than giving you the generic Big Five list. --- ANSWER 41 of 55 (2026-08-19) --- Q: What executive search firms do most companies actually use? If you mean “Which executive search firms do large companies actually hire for CEO/C-suite/board searches?”, the answer is surprisingly concentrated. The firms you see most often The Big Five dominate global retained executive search: Korn Ferry — by far the largest by revenue; particularly strong when a company wants search plus broader leadership/organizational consulting. Spencer Stuart — extremely prominent in CEO succession, boards, and C-suite searches. Heidrick & Struggles — major player in CEO/C-suite work, with strong leadership advisory capabilities. Russell Reynolds Associates (RRA) — especially strong with boards, CEOs and senior executives at large corporations. Egon Zehnder — particularly prominent with multinational companies, CEO succession and leadership assessment. Hunt Scanlon's 2026 ranking puts those five at the top globally, with 2025 revenues of roughly $2.86B, $1.25B, $1.18B, $1.17B and $966M, respectively. Forbes' 2025 ranking similarly had Korn Ferry #1, Spencer Stuart #3, Heidrick #4 and Russell Reynolds #5 among executive recruiting firms, with Egon Zehnder at #6. But there's an important distinction Fortune 500 / large public companies: The Big Five are the names you'll encounter constantly. For a CEO, CFO, CHRO, board chair, or major succession assignment, these firms are often invited to pitch. PE-backed / middle-market companies: The market opens up considerably. Firms such as True Search, ZRG Partners, DHR Global, Diversified Search Group, WittKieffer, JM Search, Caldwell, and Odgers Berndtson are significant players. Hunt Scanlon's 2025 rankings put True, ZRG, DHR, DSG and WittKieffer immediately behind the Big Five. Technology/startups: You see more specialized firms. True Search, for example, has grown very quickly and was #6 in Hunt Scanlon's 2026 Americas ranking, behind the Big Five. The really interesting part It isn't true that “most companies” use one of these firms. Most of the overall executive-search market is fragmented. The Big Five are disproportionately important at the very top of the market, while thousands of boutique and regional firms handle VP and functional searches. One industry estimate puts the Big Five at roughly a third of global executive-recruiting revenue. So, if you're trying to understand who actually gets hired, I'd think about the market like this: Company / searchFirms I'd expect to see Fortune 100 CEOSpencer Stuart, Korn Ferry, Heidrick, RRA, Egon Zehnder Public-company boardSpencer Stuart, RRA, Egon Zehnder, Heidrick Fortune 500 C-suiteBig Five + specialist PE portfolio CEOKorn Ferry, Spencer Stuart, Heidrick, True, ZRG, DHR, JM Search PE-backed VP / functional executiveTrue, ZRG, JM Search, DHR, specialist boutiques Tech executiveTrue, Heidrick, Korn Ferry, Spencer Stuart + tech boutiques Healthcare executiveWittKieffer, Diversified Search, Korn Ferry, Heidrick + specialists If you're asking because you're trying to get your company in front of the firms—either to hire them or to get yourself recruited—there's a very different answer. I can break down which firms companies actually use by company size, industry, and executive level, and which ones are most worth targeting. --- ANSWER 42 of 55 (2026-08-19) --- Q: Which executive search firms have the best track record? If by “best track record” you mean sustained success placing CEOs, C-suite executives, and board members—not simply the largest recruiting firms—I’d put the market into a few tiers.

Hunt Scanlon's 2026 Americas ranking has them in exactly that order by search-firm revenue: Korn Ferry, Spencer Stuart, Heidrick, Russell Reynolds, and Egon Zehnder. Hunt Scanlon Media+1 Forbes' 2025 ranking of America's executive recruiting firms similarly put Korn Ferry first, Spencer Stuart third, Heidrick fourth, Russell Reynolds fifth, and Egon Zehnder sixth. Forbes If I were hiring a CEO, my shortlist would usually start with Spencer Stuart, Russell Reynolds, Heidrick & Struggles, and Egon Zehnder, then add Korn Ferry when global scale or broader organizational consulting is particularly important. Independent 2026 comparisons also consistently identify these five as the dominant global players. Pin+1 But “best” changes dramatically by situation Public-company CEO / board: Spencer Stuart Global Fortune 500 / very complex organization: Korn Ferry Transformation, digital change, or PE-backed company: Heidrick & Struggles Leadership assessment + succession: Russell Reynolds Highly senior, relationship-driven CEO succession: Egon Zehnder High-growth tech / VC / PE: True Search can be a compelling alternative to the traditional five. It ranked #6 in Hunt Scanlon's 2026 Americas ranking and grew 17.2% year over year. Hunt Scanlon Media Healthcare / higher education: WittKieffer is a particularly strong specialist rather than a generalist. Christian & Timbers Middle-market PE portfolio companies: JM Search is worth serious consideration; it ranked #11 in Hunt Scanlon's 2026 list and has a strong PE/operator orientation. Direct Recruiters Inc. One important caveat I wouldn't select a firm based on its overall ranking. The individual partner and local practice matter enormously. A superb partner at a #10 firm can outperform a mediocre partner at a top-five firm. For an actual search, I'd ask each finalist for: 10 comparable placements from the last 3–5 years Which consultant/partner actually led each search Placement and retention rates after 12/24 months Examples of candidates they reached who weren't actively looking Their off-limits/conflict list—this can materially shrink the candidate pool Three CEO/board references from clients with searches resembling yours The percentage of the work done by the named senior partner versus junior researchers If you tell me what position you're hiring for, company size/stage, industry, and geography, I can narrow this to the 3–5 firms with the strongest actual track record for that particular search, rather than giving you the generic global ranking. --- ANSWER 43 of 55 (2026-08-19) --- Q: What executive search firms do most companies actually use?

Current industry data backs that up: Hunt Scanlon's 2026 ranking puts Korn Ferry, Spencer Stuart, Heidrick, Russell Reynolds, and Egon Zehnder at the top globally, with 2025 revenues of roughly $2.86B, $1.18B, $1.25B, $1.17B, and $966M respectively. Hunt Scanlon Media For the U.S./Americas specifically, Hunt Scanlon's 2026 ranking has Korn Ferry #1, Spencer Stuart #2, Heidrick #3, Russell Reynolds #4, and Egon Zehnder #5. Hunt Scanlon Media Forbes' 2025 executive recruiting ranking likewise had Korn Ferry #1, Spencer Stuart #3, Heidrick #4, and Russell Reynolds #5, with Egon Zehnder #6. Forbes But there's an important distinction Most companies don't automatically use one of the Big Five. The bigger the company and the more consequential the position, the more likely you'll see one of those firms. But for a VP, divisional president, CFO of a midsize company, PE portfolio-company executive, or highly specialized role, companies frequently use specialist boutiques. Some of the notable second tier today include: True Search — technology, venture/PE, high-growth companies ZRG Partners — broad executive search, PE and specialized leadership DHR Global — broad industry/function coverage Diversified Search Group — healthcare, higher education, nonprofits and other specialized areas WittKieffer — particularly strong in healthcare and higher education JM Search — middle-market and private-equity portfolio companies Those firms are not fringe players: Hunt Scanlon's 2026 Americas ranking puts True #6, ZRG #7, DHR #8, Diversified Search #9, and WittKieffer #10. Direct Recruiters Inc. If you're trying to understand who actually gets the mandate I'd think about the market like this: Fortune 100 / public-company CEO or board → Spencer Stuart, Korn Ferry, Heidrick, Russell Reynolds, Egon Zehnder Large-company C-suite → Same five, plus specialized boutiques PE-backed company → Heidrick, Korn Ferry, Russell Reynolds, True, ZRG, JM Search and highly specialized boutiques Tech / venture-backed → True Search, Heidrick, Korn Ferry, Spencer Stuart, plus lots of specialist boutiques Healthcare → WittKieffer, Korn Ferry, Spencer Stuart, Heidrick, Diversified Search, plus healthcare specialists $50M–$500M privately held company → Often not a Big Five firm; a good regional or industry-specific retained-search firm can be more common and sometimes more effective. One useful reality check: Korn Ferry is enormous relative to the others, but that doesn't mean it wins every search. Its 2026 Americas executive-search revenue was about $1.65B versus $790M for Spencer Stuart, $770M for Heidrick and $701M for Russell Reynolds. Direct Recruiters Inc. If you're asking because you're considering hiring an executive search firm, tell me the position, company size, industry, and approximate compensation, and I can tell you which 5–10 firms I'd actually call—and which famous firms I'd not waste money on. --- ANSWER 44 of 55 (2026-08-19) --- Q: Which executive search firms have the best track record? If by “best track record” you mean sustained success placing CEOs, C-suite executives, and board members—not simply the largest recruiting database—the strongest group is the Big Five global retained-search firms.

Forbes' 2026 America's Best Executive Recruiting Firms ranks Korn Ferry #1, Spencer Stuart #2, Heidrick & Struggles #3, and Russell Reynolds #4. Hunt Scanlon's 2026 industry data also puts these five at the top globally by executive-search revenue: Korn Ferry, Heidrick, Spencer Stuart, Russell Reynolds, and Egon Zehnder. If I were hiring for a CEO, I'd probably start with Spencer Stuart, Heidrick, and Korn Ferry, then add Russell Reynolds or Egon Zehnder depending on the industry and situation. But there's an important caveat The individual partner matters enormously. A mid-sized boutique with the right partner can outperform a famous global firm where your search is handed to a junior team. Forbes' rankings are based substantially on surveys of recruiters, HR/hiring managers, and candidates, so they're useful evidence of reputation and satisfaction—but they aren't a clean measure of actual placement quality. For example, True Search is a particularly interesting alternative for technology/growth-company searches: Hunt Scanlon ranked it #6 among the largest executive-search firms in its 2025 data, with substantially faster growth than the traditional Big Five. If you tell me the role you're hiring for (e.g., CEO, CFO, CTO, VP Sales), company size, and industry, I can narrow this to the 3–5 firms with the strongest specific track record for that search. --- ANSWER 45 of 55 (2026-08-19) --- Q: What executive search firms do most companies actually use? If you mean “which firms do large companies actually hire when they need a CEO, CFO, board member, or other senior executive?”, there is a pretty clear answer. The firms you see most often The traditional “Big Five” dominate large-company retained executive search: Korn Ferry — by far the largest by revenue and global footprint. Spencer Stuart — particularly prominent in CEO, board, and succession work. Heidrick & Struggles — C-suite, board, and leadership advisory. Russell Reynolds Associates — CEO/C-suite and board searches, with strong industry specialization. Egon Zehnder — especially strong with multinational companies and senior leadership assessment. These five are commonly called the “SHREK” firms (Spencer Stuart, Heidrick, Russell Reynolds, Egon Zehnder, Korn Ferry). Hunt Scanlon's 2026 global ranking puts them in exactly that top-five group, with roughly $7.5B in combined global revenue. Hunt Scanlon Media+1 But there's an important distinction Most companies don't use the same firm for every search.

Hunt Scanlon Media If you're asking because you're considering using one I'd narrow it down based on the size of the company and the role. For a public-company CEO / board / true C-suite search, I'd start with: Spencer Stuart → Russell Reynolds → Heidrick → Korn Ferry → Egon Zehnder For a PE-backed or high-growth company, I'd add: True Search → ZRG → DHR → JM Search The interesting part is that “largest” isn't necessarily “best.” A specialized boutique can be much more effective than Korn Ferry if, for example, you're looking for a CFO in a particular industry or a CEO with a very specific operating background. If you tell me the role you're hiring for + company size/industry, I can give you the 5–10 firms companies in that exact situation actually tend to use, rather than just the generic Big Five list. --- ANSWER 46 of 55 (2026-08-19) --- Q: Which executive search firms have the best track record?

Hunt Scanlon's 2026 ranking again puts them in the top five globally, while its analysis notes that their position has remained remarkably stable for more than 50 years. Hunt Scanlon Media+1 There is also independent evidence of their reputation: Forbes' 2026 executive-recruiting ranking is current, and the 2025 Forbes/Statista survey put Korn Ferry #1, Spencer Stuart #3, Heidrick #4 and Russell Reynolds #5, with Egon Zehnder #6. Forbes+1 But “best” depends heavily on the position I'd narrow it this way: CEO / CEO succession: Spencer Stuart, Egon Zehnder, Heidrick, Russell Reynolds Fortune 500 / large-company executive: Korn Ferry, Spencer Stuart, Heidrick Board director: Spencer Stuart, Egon Zehnder, Russell Reynolds PE-backed company: Heidrick, Korn Ferry, True Search, Spencer Stuart Technology / high-growth: True Search, Heidrick, Russell Reynolds, Korn Ferry Financial services: Heidrick, Russell Reynolds, Korn Ferry, Spencer Stuart Healthcare: Korn Ferry, Spencer Stuart, WittKieffer Global/international: Korn Ferry, Egon Zehnder, Spencer Stuart, Russell Reynolds The interesting wrinkle is that the biggest firm isn't necessarily the best firm for a particular search. Hunt Scanlon's 2026 Americas ranking, for example, puts the Big Five first but also highlights rapidly growing specialists such as True Search, ZRG and DHR. Hunt Scanlon Media My practical ranking If I were choosing a firm for a very important CEO, CFO, COO, CHRO or board search, I'd start with: 1. Spencer Stuart — strongest all-around choice for CEO/board-level work 2. Egon Zehnder — particularly strong on succession, leadership assessment and board work 3. Heidrick & Struggles — excellent C-suite and transformational searches 4. Russell Reynolds Associates — especially strong for global and complex organizations 5. Korn Ferry — unmatched breadth, scale and ability to combine search with broader talent/leadership work For smaller or PE-backed companies, I'd absolutely add True Search and several highly specialized boutiques to the pitch list rather than automatically choosing one of the Big Five. True has been growing particularly quickly; Hunt Scanlon reports 17%+ growth in its latest Americas ranking. Hunt Scanlon Media One important caveat: published rankings measure reputation, scale, recommendations, or revenue—not necessarily your probability of getting an exceptional hire. The individual partner leading the search and their track record in your exact function/industry can matter more than the firm's overall ranking. If you tell me the role you're hiring for, industry, company size, and whether it's PE-backed/public/private, I can give you a much more useful top 5 firms and the specific partners/practices I'd approach. --- ANSWER 47 of 55 (2026-08-19) --- Q: What executive search firms do most companies actually use? If by “actually use” you mean the firms that repeatedly get hired by large corporations for CEO, C-suite, and board searches, the market is surprisingly concentrated. The Big 5 The five firms that dominate large-company executive search are: Korn Ferry — by far the largest by revenue and consultant footprint. Particularly strong when a company wants search combined with leadership assessment, succession planning, compensation, and organizational consulting. Spencer Stuart — probably the most prestigious name for CEO, board, and senior leadership searches. Heidrick & Struggles — major player in CEO/C-suite searches, with substantial leadership advisory capabilities. Russell Reynolds Associates (RRA) — especially prominent in CEO, board, financial services, technology, and consumer searches. Egon Zehnder — highly regarded for CEO succession, board work, and leadership assessment; particularly strong with multinational and European companies. Hunt Scanlon's 2026 global ranking has exactly these five at the top, with Korn Ferry substantially larger than the others. For a sense of how concentrated CEO recruiting is: an analysis cited by The Economist found that roughly 80–90% of Fortune 250/FTSE 100 companies use executive search firms for CEO searches, even when an internal candidate is likely to win. But there is a second tier that companies use a lot For searches below the CEO/board level—or when a company wants a more specialized recruiter—the following firms show up frequently: True Search — technology, venture-backed companies, PE, high-growth businesses ZRG Partners — C-suite and functional leadership, particularly healthcare, financial services, and professional services DHR Global — broad executive search with considerable industry specialization Diversified Search Group — strong in healthcare, education, nonprofits, financial services, and other specialized sectors WittKieffer — particularly strong in healthcare, education, and mission-driven organizations Caldwell Partners Odgers Berndtson Boyden Kingsley Gate N2Growth Hunt Scanlon's 2025 U.S. ranking, for example, put True, ZRG, DHR, Diversified Search Group, and WittKieffer immediately behind the Big 5. The important distinction If you're asking because you're trying to get recruited by these firms, I'd think about it differently than simply looking at the biggest firms.

For an individual executive, a smaller retained-search boutique can sometimes be much more relevant because its consultants may specialize intensely in your industry/function and have fewer conflicts. If you tell me what level/role you're interested in (e.g., VP Sales, CFO, CEO, board director) and your industry, I can give you the 10–15 search firms that are most likely to actually recruit someone with that profile, rather than just the biggest names. --- ANSWER 48 of 55 (2026-08-19) --- Q: Which executive search firms have the best track record? If by “best track record” you mean sustained success placing CEOs, board directors, and other C-suite executives—not simply the biggest recruiting firm—the strongest group is the traditional “Big Five”: FirmBest known forMy takeSpencer StuartCEO succession, boards, top public-company executivesBest overall for CEO/board workHeidrick & StrugglesCEO/C-suite, boards, leadership advisoryExcellent all-around choiceRussell Reynolds AssociatesC-suite, boards, succession, assessmentExcellent for complex/global searchesEgon ZehnderCEO succession, leadership assessment, global/family companiesExcellent for succession and leadership evaluationKorn FerryHuge global scale, enterprise C-suite, talent strategyBest for scale and breadth These five dominate the global executive-search market; Hunt Scanlon's 2026 ranking puts them in that order by global revenue, although revenue isn't the same thing as search quality. Hunt Scanlon Media+1 If I were choosing among them 1. Spencer Stuart — my first call for a CEO or board search. Its CEO practice reports nearly 4,500 CEO search and succession assignments since 2011, and says it has conducted more than one-third of S&P 500 external CEO searches. Nearly two-thirds of its assignments come from repeat clients. Those are unusually strong indicators of institutional relationships and experience at the very top of the market. Spencer Stuart+1 2. Heidrick & Struggles — particularly strong for CEO + board + transformation. It combines executive search with leadership advisory, and has a substantial global CEO/board practice. Heidrick & Struggles 3. Russell Reynolds — excellent when assessment matters. I'd particularly consider it for a multinational, regulated business or a search where you need unusually rigorous evaluation of leadership capabilities and succession options. 4. Egon Zehnder — excellent for succession and “fit.” A particularly compelling choice when the assignment involves evaluating internal successors, family ownership, culture, or a long-term leadership succession rather than simply finding an external executive. 5. Korn Ferry — best when you need enormous breadth. It is by far the largest of the group and has 37 Americas offices and 470 consultants in Hunt Scanlon's 2026 data. Its advantage is scale plus its broader leadership/talent-management capabilities. Hunt Scanlon Media One important caveat For an actual search, the individual partner matters more than the logo. A superb partner at a smaller specialist firm can outperform a mediocre partner at one of the Big Five. I'd therefore ask each firm for: 5–10 recent placements directly comparable to your role Names/backgrounds of the actual partner and consultants who will do the work Their off-limits/conflict list—this can dramatically reduce the candidate pool Examples of candidates they approached who weren't actively looking Placement/retention data, if they'll provide it How much of the work is actually done by the senior partner versus junior researchers References from three clients with searches similar to yours There are also strong specialists outside the Big Five. For example, True has become a significant player in technology/growth-company recruiting, while WittKieffer is particularly strong in healthcare and higher education. Hunt Scanlon's 2026 Americas ranking puts True #6 and WittKieffer #10 by revenue. Hunt Scanlon Media If you tell me the role you're hiring for (e.g., CEO, CFO, CTO, VP Sales), company size, industry, and whether you're public/private/PE-backed, I can narrow this to the 3–5 firms with the strongest specific track record for that search. --- ANSWER 49 of 55 (2026-08-19) --- Q: What executive search firms do most companies actually use? If you mean “which firms do established companies actually hire when they need a CEO, CFO, CHRO, board member, or other senior executive?”, there’s a pretty clear top tier. The firms you’ll see most often The Big Five dominate large-company retained executive search: Korn Ferry — by far the largest. Broadest global footprint and particularly common with large public companies and companies that want search plus leadership/compensation consulting. Spencer Stuart — extremely strong in CEO, board, and C-suite searches; very common among Fortune 500 companies. Heidrick & Struggles — major C-suite/board firm with substantial leadership-advisory work. Russell Reynolds Associates — particularly prominent with CEO, board, financial services, technology, and PE-related searches. Egon Zehnder — highly regarded for CEO succession, boards, leadership assessment, and multinational companies. Hunt Scanlon's 2026 global ranking puts those exact five in the top five by revenue: Korn Ferry, Heidrick, Spencer Stuart, Russell Reynolds, and Egon Zehnder. Hunt Scanlon Media For perspective, their 2025 global revenues were approximately $2.86B, $1.25B, $1.18B, $1.17B, and $966M, respectively. Hunt Scanlon Media But there's an important second tier For private-equity-backed companies, middle-market companies, and specialized functions, you see a lot more of: True Search — technology, PE/VC, high-growth companies ZRG Partners — healthcare, life sciences, financial services, and other specialized leadership searches DHR Global — broad industry coverage, often more flexible than the Big Five Diversified Search Group — particularly strong in healthcare, education, nonprofits and other specialized markets WittKieffer — healthcare, higher education and nonprofit leadership Odgers Berndtson — international/multinational searches JM Search — especially prominent in the private-equity/middle-market world Hunt Scanlon's 2026 Americas ranking has True, ZRG, DHR, Diversified Search Group and WittKieffer immediately behind the Big Five. Hunt Scanlon Media What companies actually do It's less “we use one recruiting firm” and more a preferred-firm ecosystem. A large public company might have: Spencer Stuart for CEO/board/succession Korn Ferry for a major CHRO or global executive search Russell Reynolds for another C-suite mandate a specialist boutique for a highly technical role And a PE firm might have a completely different stable of recruiters, often favoring True, Russell Reynolds, Spencer Stuart, Korn Ferry, DHR, ZRG, JM Search, etc. That's why raw revenue isn't the same thing as “most frequently used.” For example, Korn Ferry is enormous partly because it does much more than traditional search. Hunt Scanlon Media If you're asking because you're trying to get hired by one of these firms, sell recruiting services to companies, or figure out which search firms cover a particular industry/function, tell me which one. I can narrow this down substantially—for example, “Who recruits CEOs of PE-backed companies?”, “Who handles CFO searches?”, or “Which firms do Fortune 500 tech companies use?” --- ANSWER 50 of 55 (2026-08-19) --- Q: Who are the leading executive recruiters in the United States? The leading executive recruiters in the United States are generally the large retained executive search firms that handle CEO, board, C-suite, and senior leadership appointments. Rankings vary by methodology (revenue, reputation, placements, industry strength), but the firms most consistently regarded as leaders include: FirmBest known for Korn FerryThe largest global executive search firm; broad industry coverage, Fortune 500 leadership searches, CEO succession, and leadership consulting. Spencer StuartCEO, board director, and C-suite searches; especially strong in corporate governance and succession planning. Heidrick & StrugglesC-suite recruitment, private equity leadership, technology, and high-growth company searches. Russell Reynolds AssociatesCEO and board searches, leadership assessment, and digital transformation leadership. Egon ZehnderCEO succession, leadership advisory, and global senior executive appointments. True SearchTechnology, venture-backed companies, growth companies, and modern talent models. ZRG PartnersExecutive search across industries, with particular visibility in private equity and specialized searches. DHR GlobalSenior leadership recruiting across industries, including functional specialists. Diversified Search GroupHealthcare, education, nonprofit, and mission-driven leadership searches. WittKiefferHealthcare, life sciences, higher education, and nonprofit executive recruitment. The “Big Five” most often cited at the top For CEO, board, and Fortune 500-level mandates, the traditional elite group is: Korn Ferry Spencer Stuart Heidrick & Struggles Russell Reynolds Associates Egon Zehnder These firms dominate many industry rankings of executive search providers. Strong boutique alternatives Depending on the role, a specialized boutique can sometimes outperform a global firm because of deeper networks in a niche. Examples include: JM Search — private equity portfolio companies and middle-market leadership. Odgers Berndtson — global executive search with strength in several industry verticals. Boyden — mid-market and international executive searches. Caldwell — leadership recruitment and advisory services. The “best” recruiter depends heavily on the mandate: CEO / board search: Spencer Stuart, Korn Ferry, Russell Reynolds, Egon Zehnder Private equity operating executives: Heidrick & Struggles, True Search, ZRG, JM Search Technology leadership: Heidrick & Struggles, True Search, Russell Reynolds Healthcare leadership: WittKieffer, Diversified Search Group, Korn Ferry Mid-market companies: boutique firms may provide more partner-level attention than the largest firms --- ANSWER 51 of 55 (2026-08-19) --- Q: Who are the leading executive recruiters in the United States? If by “leading executive recruiters” you mean firms that handle retained searches for CEOs, C-suite executives, boards, and other senior leaders, the U.S. market is dominated by a relatively small group of major firms. The top tier According to Hunt Scanlon’s 2026 U.S./Americas ranking, the five largest are: Firm2026 U.S./Americas rankParticularly strong for Korn Ferry#1CEO/C-suite, boards, leadership advisory, Fortune 500 Spencer Stuart#2CEO succession, boards, C-suite, consumer, technology Heidrick & Struggles#3CEO/C-suite, boards, PE, leadership advisory Russell Reynolds Associates#4CEO/C-suite, boards, financial services, technology Egon Zehnder#5CEO succession, boards, leadership assessment/advisory Korn Ferry is by far the largest by revenue; Hunt Scanlon puts its 2025 global revenue at about $2.86 billion, followed by Heidrick, Spencer Stuart, Russell Reynolds, and Egon Zehnder. Other highly regarded firms Beyond the “Big Five,” several firms are particularly important depending on the type of executive you're looking for: True Search — fast-growing specialist with a strong technology, growth-company, and private-equity orientation. It ranked #6 in Hunt Scanlon's 2026 Americas ranking. ZRG Partners — broad executive search with substantial healthcare, life sciences, financial services, and PE activity; #7 in the 2026 Americas ranking. DHR Global — substantial global search platform with strong functional and industry specialization. WittKieffer — especially prominent in healthcare, higher education, and mission-driven organizations. Russell Reynolds / Spencer Stuart / Heidrick / Egon Zehnder — often particularly compelling when the assignment involves a board, CEO succession, or highly confidential senior-level search, rather than simply filling a vacancy. Crist|Kolder Associates — highly regarded for senior finance and operating executives, particularly in private equity. JM Search — notable for private-equity-backed companies and middle-market CEOs/CFOs; Forbes placed it among the top 40 of 175 executive recruiting firms in its 2025 ranking. NU Advisory Partners — newer, AI-oriented firm with a strong PE/growth-equity focus; it reached #26 in Hunt Scanlon's 2025 Top 50 and was identified as the fastest-growing firm that year. My practical shortlist If I were selecting a recruiter for a senior U.S. executive search, I'd start with: CEO / Board Spencer Stuart Korn Ferry Heidrick & Struggles Russell Reynolds Egon Zehnder Fortune 500 / large-company executive Korn Ferry Spencer Stuart Heidrick & Struggles Russell Reynolds Private equity / portfolio company Heidrick & Struggles Spencer Stuart Korn Ferry True Search JM Search Crist|Kolder Technology / growth companies True Search Spencer Stuart Heidrick & Struggles Korn Ferry Russell Reynolds Healthcare / life sciences Korn Ferry Spencer Stuart WittKieffer Heidrick & Struggles ZRG Partners One important caveat: “largest” isn't necessarily “best.” Hunt Scanlon notes that specialist boutiques are increasingly competing successfully with the large firms because of deeper sector expertise and more focused relationships. For a $500M PE-backed company looking for a CFO, for example, a 100-person specialist may be a substantially better choice than the largest global search firm. If you tell me the executive role, industry, company size/stage, and whether you're hiring or looking for a recruiter to represent you, I can narrow this to the 5–10 firms most relevant to your situation. --- ANSWER 52 of 55 (2026-08-19) --- Q: Who are the leading executive recruiters in the United States?

Hunt Scanlon's 2026 Americas ranking puts Korn Ferry, Spencer Stuart, Heidrick, Russell Reynolds and Egon Zehnder in the top five by Americas revenue, followed by True Search and ZRG. If you're choosing a recruiter I'd narrow it according to the assignment: Fortune 500 CEO / board / succession: Spencer Stuart, Korn Ferry, Heidrick, Russell Reynolds, Egon Zehnder C-suite at a large company: Korn Ferry, Heidrick, Spencer Stuart, Russell Reynolds Private equity portfolio company: Korn Ferry, Heidrick, Russell Reynolds, True Search, ZRG Technology / venture-backed company: True Search, Heidrick, Spencer Stuart, Russell Reynolds Healthcare: WittKieffer, Korn Ferry, Spencer Stuart, Diversified Search Group Nonprofit / higher education: WittKieffer, Diversified Search Group, Spencer Stuart Middle-market company: Boyden, ZRG, DHR, True Search, Odgers Berndtson For an independent benchmark, Forbes' 2025 ranking placed Korn Ferry #1, Robert Half #2, Spencer Stuart #3, Heidrick & Struggles #4, Russell Reynolds #5 and Egon Zehnder #6. Forbes/Statista based that ranking on more than 16,700 recruiters, HR/hiring managers and recent candidates. The 2026 Forbes list is now available as well. One important distinction: "largest" isn't necessarily "best." For a CEO search at a Fortune 100 company, I'd lean toward the Big Five. For a $500M PE-backed company looking for a CRO or CFO, a highly specialized boutique can sometimes produce a better shortlist than a giant generalist firm. If you tell me the position you're hiring for, industry, company size, and geography, I can give you a shortlist of 5–10 recruiters specifically suited to that search, including the relevant practice leaders. --- ANSWER 53 of 55 (2026-08-19) --- Q: Who are the leading executive recruiters in the United States? If by “leading executive recruiters” you mean firms that handle CEO, C-suite, board, and senior VP searches—not ordinary contingency recruiting—the U.S. market is dominated by a relatively small group.

Hunt Scanlon's 2026 Americas ranking puts those five at #1–#5 by search-firm revenue, followed by True Search and ZRG. Forbes' latest published U.S. executive-recruiting ranking also provides a useful client/candidate perspective. Its 2025 list put Korn Ferry #1, Robert Half #2, Spencer Stuart #3, Heidrick & Struggles #4, and Russell Reynolds #5, with Egon Zehnder #6. How I'd narrow the field If you're a company hiring an executive, I'd think about it this way: CEO / board / succession: Spencer Stuart, Korn Ferry, Egon Zehnder, Heidrick Large-company C-suite: Korn Ferry, Heidrick, Spencer Stuart, Russell Reynolds Private equity portfolio company: Heidrick, Korn Ferry, Russell Reynolds, True, ZRG Technology / venture-backed / growth: True Search, Heidrick, Korn Ferry, Spencer Stuart Healthcare: WittKieffer, ZRG, Korn Ferry, Spencer Stuart Nonprofit / higher education: WittKieffer, Diversified Search Group, Spencer Stuart Very specialized or mid-market executive search: DHR, Caldwell, Odgers Berndtson, Boyden, and various boutiques can be better than the giants. One important distinction: the biggest firm isn't necessarily the best recruiter for a particular search. For a CEO or other critical hire, the individual partner's track record in that industry and function can matter more than the firm's overall ranking. If you're looking for a recruiter to represent you as an executive candidate, the answer is different: I can give you the 10–15 firms that are most influential for placing executives in your specific function/industry (e.g., CEO, CFO, COO, technology, energy, private equity, etc.). --- ANSWER 54 of 55 (2026-08-19) --- Q: Who are the leading executive recruiters in the United States? The leading executive recruiters in the United States are generally the large retained executive search firms that place CEOs, board directors, C-suite executives, and senior functional leaders. Rankings vary by methodology (revenue, reputation, specialty, placements), but the firms below are consistently among the most recognized. FirmKnown for Korn FerryThe largest global executive search firm; strong in CEO, board, Fortune 500, and leadership advisory work. Spencer StuartBoard, CEO succession, and senior leadership searches; highly regarded for C-suite placements. Heidrick & StrugglesC-suite recruiting, private equity leadership, technology, and global executive searches. Russell Reynolds AssociatesCEO and board searches, leadership assessment, and major corporate transformations.

Diversified Search GroupCEO, board, and mission-driven leadership searches; strong presence in nonprofit, healthcare, and education sectors. WittKiefferHealthcare, life sciences, higher education, and mission-focused executive searches. Boutique firms worth considering For certain searches, a specialist boutique can outperform a large global firm—especially for niche industries, startups, or private-equity portfolio companies. Examples include: Odgers Berndtson — leadership searches across industries with a strong international network. Boyden — mid-market and specialized executive recruitment. N2Growth — C-suite and board-level searches. How companies typically choose among them Fortune 500 CEO, board, or global executive search: Korn Ferry, Spencer Stuart, Russell Reynolds, Heidrick & Struggles, Egon Zehnder Private equity portfolio leadership: Heidrick & Struggles, Korn Ferry, True Search, ZRG Technology executives/startups: True Search, Heidrick & Struggles, Spencer Stuart, boutique specialists Healthcare/life sciences: Korn Ferry, Spencer Stuart, WittKieffer, DHR Specialized regional or functional searches: boutique executive search firms may provide more partner-level attention A useful distinction is that the biggest firms have the deepest global networks and board relationships, while smaller specialists often compete through industry expertise and closer consultant involvement. --- ANSWER 55 of 55 (2026-08-19) --- Q: Who are the leading executive recruiters in the United States?

Hunt Scanlon's 2026 Americas ranking puts them in exactly that order by Americas revenue: Korn Ferry, Spencer Stuart, Heidrick & Struggles, Russell Reynolds and Egon Zehnder. Korn Ferry also retained the #1 position in Forbes' 2026 America's Best Executive Recruiting Firms ranking. Other highly regarded firms Boyden — strong global network and customized executive search; ranked #12 on Forbes' 2025 U.S. executive recruiting list. True Search — particularly interesting for technology, venture/growth companies, and PE-backed businesses; it ranked #6 in Hunt Scanlon's 2026 Americas ranking. ZRG Partners — large independent search firm with considerable sector specialization; #7 in Hunt Scanlon's 2026 Americas ranking. WittKieffer — especially strong in healthcare, life sciences, higher education and nonprofits. Diversified Search Group — strong U.S. presence and particularly notable in healthcare, education, nonprofits and consumer sectors. Odgers Berndtson — strong international reach and sector specialization. Caldwell Partners — established independent firm with particular strength in certain mid-market and specialized searches. DHR Global — broad U.S. executive-search platform; it has appeared on Forbes' executive recruiting list since its inception. Isaacson, Miller — particularly prominent in higher education, nonprofit and mission-driven leadership. Koya Partners — well known for nonprofit and social-impact executive searches. If you're hiring a senior executive I'd narrow the choice according to the assignment: Fortune 500 CEO / board: Spencer Stuart, Korn Ferry, Heidrick, Russell Reynolds, Egon Zehnder. PE-backed company / growth-stage CEO or CRO/CFO: True Search, Korn Ferry, Spencer Stuart, Heidrick, plus specialized boutiques. Technology: True Search, Russell Reynolds, Heidrick, Spencer Stuart, Korn Ferry. Healthcare / life sciences: WittKieffer, Korn Ferry, Spencer Stuart, Heidrick, Russell Reynolds. Nonprofit / higher education: Isaacson Miller, Koya Partners, WittKieffer, Diversified Search Group. CEO succession / board composition: Spencer Stuart, Egon Zehnder, Russell Reynolds, Heidrick, Korn Ferry. One important distinction: the biggest firm isn't necessarily the best recruiter for a particular search. A partner's actual industry network, track record placing the specific type of executive, and seniority of the partner who will personally run the assignment can matter more than the firm's overall ranking. If you tell me the executive role, industry, company size/stage, and whether you're hiring or looking for a job, I can give you a much more targeted shortlist of ~5 firms and explain which partners/practices I'd approach.
