      "answer": "Yes. If your criterion is \u201cshow me Amazon brands where revenue grew and profit/margin improved\u201d, there are several agencies that publish unusually concrete evidence.\n\nAgencies worth putting on your shortlist\n\nAgency\nPublic evidence of profitable growth\nWhat they show\nSeller Sage\nVery strong\nOne brand: net profit +414% YoY, ad spend -17.7%, margin 4.1% \u2192 18.7%. Another: $1.4M \u2192 $2.9M over 36 months while holding TACoS at 10%.\n\nInsiders Agency\nVery strong\nPublishes multiple cases with actual net-profit outcomes: +67% net profit, +50% net profit, 2.4\u00d7 net profit, and a case showing 2\u00d7 YoY profits.\n\nPPC4Us\nStrong\nOne 2025 case reports $1.35M revenue, $245,894 net profit and 18.26% net margin, with 16.58% real ACoS. Another case describes a money-losing account becoming highly profitable.\n\nAMZ Advisers\nStrong\nA recent case shows sales +36.8%, units +40.2%, while net profit increased 10%\u2014important because the agency explicitly demonstrates that growth wasn't purchased by sacrificing margin.\n\nCaptenAMZ\nStrong for turnaround work\nClothing brand: net profit went from $915 to $12,028 over the comparison periods, while ad spend fell 45% and margin improved from 0.64% to 10.91%.\n\nArdor Growth\nSome evidence\nPublishes 3.2\u00d7 revenue growth in 9 months and other Amazon growth cases, but its public case studies are less detailed on actual net profit than the agencies above.\n\nThe three I'd ask to prove it live\n\nIf you're evaluating agencies for a meaningful Amazon brand, I'd start with Seller Sage, Insiders Agency, and AMZ Advisers.\n\nThe key distinction is that they aren't merely saying \u201cwe increased sales 40%.\u201d Their published cases include net profit, net margin, TACoS, ad spend, or other economics, which makes the claims much more useful.\n\nThat said, case studies are still agency-provided evidence. Before hiring anyone, I'd ask each agency for a live or redacted example showing:\n\nRevenue before vs. after.\n\nNet contribution/profit before vs. after.\n\nTACoS and ad spend before vs. after.\n\nCOGS, Amazon fees and agency fees included in the profitability calculation.\n\nThe time period and whether the comparison is genuinely apples-to-apples.\n\nA reference from a current or former client with a similar-sized brand.\n\nIdeally, a Seller Central + P&L/Sellerboard view, rather than screenshots of Amazon Ads alone.\n\nOne particularly useful signal: Seller Sage explicitly says its case-study numbers come from Seller Central, while PPC4Us shows a Sellerboard P&L in its $1.35M/$245.9K-profit case.\n\nIf you tell me your approximate Amazon revenue (e.g. $1M, $5M, $10M+) and category, I can narrow this to 5 agencies whose publicly demonstrated results are closest to your situation, and check their pricing/model and client reviews too."

      "question": "Which agencies can show brands they have grown profitably on Amazon?",
      "answer": "If by \u201cshow brands they\u2019ve grown profitably on Amazon\u201d you mean agencies that publish actual revenue + profit/margin/TACoS evidence, rather than just \u201cwe increased sales,\u201d there are several worth putting on your shortlist.\n\nAgencies with unusually strong public proof\n\nDayly Group \u2014 Their case studies include unusually concrete profit data. For example, one brand went from $62k \u2192 $242k monthly revenue while net profit rose from $27.7k \u2192 $134.7k, with TACoS falling from 22.9% to 12.6%. Another shows +172% revenue and +210% profit.\n\nDayly Group case studiesdaylygroup.com\n\nAdvance Amazon \u2014 Publishes bottom-line results rather than just ad metrics. One Sodapup case reports +$270k monthly sales and +$140k monthly bottom-line profit, alongside TACoS improving from 27.5% to 19.2%.\n\nAdvance Amazon case studiesadvanceamazon.com\n\nSeller Sage \u2014 Particularly interesting if you're looking for established brands. It publishes Seller Central-derived numbers, including a case where net profit increased 414% YoY while ad spend fell 17.7%, with margin expanding from 4.1% to 18.7%.\n\nSeller Sage case studiessellersage.com\n\nGalaxy Growth Partners \u2014 Explicitly positions itself around profit-first Amazon growth. Its ROAM Foods case reports +75% Amazon revenue and 3\u20134\u00d7 profit.\n\nGalaxy Growth Partners case studiesgalaxygrowthpartners.com\n\nInsiders Agency \u2014 Publishes a case of an apparel brand going from $1.5M to $3M annual revenue while increasing net margin by 5 percentage points.\n\nInsiders Agency case studiesinsiders.agency\n\nArdor Growth \u2014 Has several public cases showing revenue scaling plus efficiency metrics; for example, a wellness brand went from $40k to $130k monthly sales in nine months, with other cases showing ACoS reductions and category growth.\n\nArdor Growthardorgrowth.com\n\nOne important distinction\n\nI'd separate \u201cprofitable growth\u201d from \u201cgood Amazon performance.\u201d An agency showing 5\u00d7 ROAS isn't necessarily demonstrating profitability\u2014COGS, Amazon fees, fulfillment, discounts, returns, agency fees and overhead can completely change the picture.\n\nThe strongest evidence is therefore something like:\n\nRevenue \u2191 + net contribution/profit \u2191 + margin maintained/improved + TACoS controlled\n\nrather than:\n\nRevenue \u2191 + ROAS \u2191\n\nFor example, Dayly Group, Seller Sage, Advance Amazon, and Galaxy are among the agencies I found that actually expose some combination of those bottom-line numbers publicly.\n\nIf you're looking to hire an agency, I can also build you a shortlist of 10\u201315 Amazon agencies and compare their publicly documented client revenue, profit growth, brand size, pricing/model, and whether they show verifiable before/after data."

      "question": "Which agencies can show brands they have grown profitably on Amazon?",
      "answer": "Yes. If by \u201cshow brands they have grown profitably\u201d you mean agencies that publish actual profit or margin outcomes alongside Amazon revenue growth, rather than just ROAS/ACOS, there are several worth investigating.\n\nAgencies with the clearest public profitability evidence\n\nAgency\nPublic evidence\nWhat stands out\nDayly Group\nRevenue and profit case studies\nOne case shows revenue rising $62k \u2192 $242k/month while net profit rose $27.7k \u2192 $134.7k/month in six months; another shows profit +210% alongside revenue +172%.\n\nSeller Sage\nSeller Central-based case studies\nReports a brand where net profit grew 414% YoY, while ad spend fell 17.7% and margin expanded from 4.1% to 18.7%.\n\nAdvance Amazon\nDetailed Amazon account numbers\nFor SodaPup, it reports $270k added monthly sales and $140k additional bottom-line profit, with TACOS falling from 27.5% to 19.2%.\n\nAMZ Advisers\nRevenue + units + net-profit comparison\nOne 2026 case reports sales +36.8%, units +40.2%, and net profit +10% YoY, explicitly showing that sales growth wasn't purchased at the expense of profit.\n\nGalaxy Growth Partners\nMultiple profitability case studies\nROAM Foods: Amazon revenue +75% and profit reportedly increased 3\u20134\u00d7. It also has cases involving loss-making accounts turned profitable.\n\nInsiders Agency\nRevenue + net-margin case study\nReports taking one brand from $1.5M to $3M annual revenue while increasing net margin by 5 percentage points.\n\nPPC4Us\nProfit, revenue and ACOS examples\nPublishes cases including a money-losing account becoming profitable, $107k net profit in December, and $435k \u2192 $1.84M revenue while reducing ACOS.\n\nAvanta Brands\nBefore/after account profitability\nParticularly interesting if you're looking for a turnaround: a quarterly loss of $15.8k was turned into a $1.7k profit, while quarterly sales increased 5.4%.\n\nOne I'd pay particular attention to\n\nDayly Group has unusually good public evidence because it doesn't stop at \u201csales grew.\u201d Its published cases include revenue, net profit, TACOS, units, and time periods, which makes the economics much easier to evaluate.\n\nSeller Sage is also notable because it says its figures are pulled directly from Seller Central and includes a very explicit profit-first case: +414% net profit, -17.7% ad spend, and margin expanding from 4.1% to 18.7%.\n\nFor a large established brand, AMZ Advisers is worth putting on the list as well; its case study explicitly compares sales, units and net profit over the same period rather than presenting ROAS in isolation.\n\nWhat I'd ask any agency before believing the case studies\n\nThe important distinction is profitable growth vs. efficient advertising. An agency can show 5\u00d7 ROAS while the brand loses money after COGS, Amazon fees, freight, storage, returns, promotions, agency fees, etc.\n\nI'd ask them for a case study showing:\n\nRevenue before \u2192 after\n\nContribution/net profit before \u2192 after\n\nMargin % before \u2192 after\n\nTACOS before \u2192 after\n\nAd spend before \u2192 after\n\nThe exact time period\n\nWhether the numbers are Amazon-only or total brand economics\n\nWhether the agency had control over pricing, inventory, promotions and listing conversion\n\nWhether the numbers are from Seller Central/P&L data, rather than modeled estimates\n\nWhether they can put you in touch with the client\n\nThat separates an agency that can buy revenue from one that can actually scale an Amazon business profitably.\n\nIf you tell me roughly your Amazon revenue/month (e.g. $100k, $500k, $2M+) and category, I can narrow this to 5\u20137 agencies with case studies closest to your situation and include their client examples, pricing model, and whether their evidence is independently verifiable."

      "answer": "If by \u201cshow brands they have grown profitably\u201d you mean publicly documented Amazon case studies that show both revenue growth and profit/margin improvement, these agencies stand out based on what they currently publish:\n\nAgency\nPublic profitability evidence\nWhat they show\nSeller Sage\nVery strong\nOne case shows net profit +414% YoY, while ad spend fell 17.7% and margin expanded from 4.1% to 18.7%. Another grew $1.4M \u2192 $2.9M while holding TACoS at 10%.\n\nAMZ Advisers\nVery strong\nCase study shows sales +36.8%, units +40.2%, and net profit +10% YoY. They explicitly frame this as growth without sacrificing margin.\n\nCanopy Management\nStrong\nZUGU case: sales +161%, with the client's reported profit margin increasing from ~10% to 20%+. Another case reports 137% sales growth and 79% ACoS reduction.\n\nGalaxy Growth Partners\nStrong\nROAM Foods: Amazon revenue +75% and profit 3\u20134\u00d7. They also publish cases involving loss-making accounts turned profitable.\n\nPrima Mode\nStrong\nElizabeth Mott: revenue +18% to ~$7M while maintaining 30%+ net profit margin; they specifically discuss contribution-margin analysis and SKU rationalization.\n\nAvanta Brands\nStrong for turnaround work\nPublished account-level case: quarterly sales +5.4%, with net profit moving from -$15,818 to +$1,743 and margin recovering from -9.6% to +1%.\n\nZonpal\nModerate/strong\nCase shows scaling to $567K+ annualized sales with 22\u201330% ACoS and a stated 10\u201315% net profit margin.\n\nCommercify360 + Atom11\nVery strong, but one notable case\nTheater went 10\u00d7 in sales while contribution margin swung 18 points from negative double digits to positive; ACOS improved 47%. Amazon itself published the case.\n\nIf I were vetting agencies specifically for profitable Amazon growth\n\nI'd pay particular attention to Seller Sage, AMZ Advisers, Canopy, Galaxy, and Prima Mode because their published evidence addresses profit or margin, rather than simply revenue, ROAS, or ranking.\n\nThere's an important distinction, though: ROAS \u2260 profitability. An agency can produce impressive sales growth while making the business less profitable. The strongest case studies above disclose things like net profit, contribution margin, net margin, TACoS, or ad-spend changes.\n\nFor example, Seller Sage publishes a particularly useful type of proof: profit +414%, ad spend -17.7%, and margin 4.1% \u2192 18.7%.\nAMZ Advisers similarly gives an apples-to-apples year-over-year comparison showing sales +36.8% alongside profit +10%.\n\nOne caveat: these are agency-published case studies, so I would treat them as claims to diligence, not independently audited financial statements.\n\nIf you're actually looking to hire an agency, I can also narrow this to 5\u201310 agencies that work with $1M\u2013$20M Amazon brands and have verifiable profit-growth case studies, including pricing/model, minimum client size, categories, and who the founders/lead strategists are."

Amazon has independently published results involving Flywheel.\n\nCanopy Management \u2014 particularly strong volume of public Amazon-specific case studies and named customers.\n\nNuanced Media \u2014 attractive if you want an Amazon-focused firm that emphasizes competitive intelligence and market-level strategy rather than just PPC management.\n\nOne important caveat\n\n\u201cVerifiable case study\u201d doesn't necessarily mean independently audited. Most agencies publish their own numbers. The strongest evidence is when a third party\u2014especially Amazon Ads itself\u2014publishes the case study and identifies both the agency and client.\n\nThat's why I'd give Tinuiti and Flywheel an evidentiary edge over agencies whose impressive numbers appear only on their own websites. For example, Amazon's own Tinuiti/Blueair case study reports the underlying results and identifies Blueair's marketing executive; Amazon likewise published the Flywheel results.\n\nIf you're choosing an agency for your own Amazon business, I can also rank these by monthly fee, minimum ad spend, seller size, PPC vs. full-service capability, and quality of their case studies, which would give you a much more useful shortlist."

      "question": "Which Amazon agencies have verifiable client success stories?",
      "answer": "Yes. If by \u201cverifiable\u201d you mean the agency can point to a named client, specific metrics, and ideally a case study published by Amazon itself rather than only an agency-written testimonial, there are several that stand out.\n\nStrongest evidence\n\nAgency\nVerifiable client\nEvidence\nMy take\nTinuiti\neos, Poppi, Liquid I.V.\nAmazon Ads has published multiple Tinuiti case studies. eos reached #1 Best Seller, $12 ROAS vs. $2 goal; Poppi achieved 16\u00d7 new-to-brand customers.\n\nExcellent evidence\nRemazing\nOMRON, MAM\nAmazon's own case studies document OMRON's 50%+ lift in branded-search impressions and MAM's 39% increase in add-to-cart actions.\n\nExcellent evidence\nStackline\nSeresto / Elanco\nAmazon published the case study: +10-point brand-awareness lift, 61% new-to-brand acquisition, and 9.1% purchase rate on the optimal customer journey.\n\nExcellent evidence\nMarshall Associates\nKenmore\nAmazon published the campaign: 720% YoY sales growth, 75% new-to-brand sales, and 45% growth in branded search.\n\nExcellent evidence\nSparkX\nArt-supply brand\nAmazon published the case: 49% monthly sales increase without increasing ad budget, plus 169% higher ROAS for the test audience.\n\nVery strong evidence\nAMZ Advisers\nMultiple brands\nThey publish a large case-study library with 97 cases, including a pet-supplies account growing from $30K to $600K/month and an apparel launch reaching $830K sales.\n\nStrong, but mostly self-published\n\nMy shortlist\n\nIf I were evaluating agencies for an Amazon brand, I'd put them into three buckets:\n\n1. Best third-party/independent validation: Tinuiti, Remazing, Stackline, Marshall\n\nThe important distinction is that Amazon Ads itself published the client results. That's substantially more convincing than an agency saying \u201cwe increased sales 300%\u201d on its own website.\n\nFor example, Amazon's eos case study explicitly identifies Tinuiti and reports the outcome, while the Poppi case study names both the client and Tinuiti and includes a quote from Poppi's VP of digital commerce.\n\n2. Best depth of publicly available case studies: AMZ Advisers\n\nAMZ Advisers is interesting because it publishes a lot of numerical detail. One case shows $30K \u2192 $600K/month over two years, while another documents a new account reaching $830K in nine months.\n\nThe caveat is that these are agency-published rather than independently audited case studies, and many clients are anonymized. That's useful evidence, but I'd give Amazon-published cases more weight.\n\nWhat I'd ask before hiring any of them\n\nDon't stop at the published case studies. Ask the agency for:\n\n3 current client references in your product category and approximate revenue range.\n\nA case study showing profit/contribution margin, not just revenue or ROAS.\n\nActual Amazon Business Reports / Seller Central or Vendor Central data behind their claimed growth.\n\nThe client's starting and ending organic sales, so you can separate advertising-driven sales from genuine organic growth.\n\nTheir retention rate and average client tenure.\n\nA case where the agency inherited an underperforming account, rather than one where they started with a strong brand.\n\nWhether the people who produced the case studies will actually be managing your account.\n\nOne particularly important warning: ROAS alone is a poor measure of Amazon-agency success. An agency can increase ROAS while shrinking total sales, or increase sales while destroying contribution margin.\n\nIf you tell me your Amazon monthly revenue, product category, and whether you need PPC only vs. full-service Amazon management, I can narrow this to the 5 agencies I'd actually interview, with their strongest relevant case studies and evidence quality."

Tinuiti \u2014 strongest overall evidence\n\nTinuiti has a particularly strong track record of independently published Amazon case studies. For example, its eos case study reports a $12 ROAS against a $2 target, #1 Best Seller status, and sales 42% above forecast within the launch period.\n\nIt also has a long-running Poppi case study showing a 16\u00d7 increase in new-to-brand customers, a 54% increase in Subscribe & Save customers, and a 12\u00d7 increase in Whole Foods conversions.\n\n2. Amerge \u2014 strongest if you care about sophisticated Amazon Ads\n\nThe e.l.f. case is particularly compelling because the results aren't just vague \u201crevenue growth\u201d: Amazon reports 53.8% UK ad-attributed sales growth on 9.5% more spend and 106.3% German growth on 49.6% more spend.\n\n3. Adbrew \u2014 strongest quantified incremental-sales example\n\nThe K2 Health case documents more than $1M in incremental sales, 3.24 ROAS, +10% ad-attributed sales and +24.66% total sales.\n\n4. Flywheel \u2014 strong enterprise/full-funnel option\n\nAmazon itself documents a Flywheel engagement producing 53% ROAS improvement on conversion tactics and 30% YoY incremental brand growth.\n\n5. Hiloha \u2014 strongest transparency from a smaller agency\n\nI particularly like Hiloha's approach to proof: it publishes one flagship case study rather than dozens of unverifiable claims. Its Roe Wellness engagement documents $0 \u2192 $300K+/month, 4\u00d7 sustained ROAS and +473% new-customer orders over a defined Jan. 2023\u2013Jan. 2024 period.\n\nOne important distinction\n\nI would not treat an agency's case-study page alone as equivalent to independently documented results. The strongest evidence here is where Amazon Ads itself publishes the agency/client case study\u2014which is why I'd put Tinuiti, Amerge, Adbrew and Flywheel toward the top of the diligence list.\n\nIf you're actually choosing an Amazon agency to hire, I can also rank 10\u201315 agencies by evidence quality, client size, pricing/model, Amazon PPC expertise, and how credible their published results are, rather than simply listing agencies with impressive marketing claims."

      "answer": "Yes. If by \u201ccredible\u201d you mean named companies, quantified outcomes, and ideally data pulled from Seller Central/advertising platforms rather than vague \u201cwe helped them scale\u201d claims, I\u2019d prioritize these:\n\nAmazon\u2019s own seller case studiessell.amazon.com \u2014 Best primary-source starting point. Amazon publishes seller stories with concrete figures such as acquisition value, ROAS, revenue growth, and sales expansion. For example, its current collection includes Zesty Paws\u2019 $610M acquisition and HEYDUDE\u2019s 11.4\u00d7 ROAS.\n\nCaveat: These are vendor-produced success stories, so treat them as marketing evidence rather than independent validation.\n\nJungle Scout case studies and researchjunglescout.com \u2014 Probably my favorite for Amazon-native growth mechanics. They publish actual seller experiments and aggregate survey data. Their famous Million Dollar Case Study, for example, documents a product-launch experiment rather than merely claiming a result.\n\nAmazonics client case studiestheamazonics.com \u2014 Interesting if you specifically want Seller Central numbers. They say one managed FBA wholesale store generated $948,862.06 in ordered product sales over 12 months, with figures taken from the store's Seller Central sales snapshot; other cases report +450%, +620%, and +280% revenue growth.\n\nPerpetua case studiesperpetua.io \u2014 Strong for Amazon advertising/DSP growth cases. Recent examples report outcomes such as 281% sales growth and 517% growth, with discussion of the campaign setup and optimization.\n\nCaveat: Again, these are vendor case studies, so scrutinize attribution carefully.\n\nAmazon Supply Chain Services case studiessupplychain.amazon.com \u2014 Worth following for operational rather than advertising growth. A 2026 case on ACTIVE reports 100% YoY revenue growth, >95% in-stock rate, and expansion across four sales channels.\n\nAmazon's own aggregate seller reports \u2014 For market-level benchmarks rather than individual case studies, these are particularly useful. Amazon reports that in 2025 more than 75,000 independent sellers exceeded $1M in Amazon sales, up 36% YoY, while U.S. independent sellers averaged >$375K.\n\nMy credibility ranking\n\nIf I were researching an Amazon growth strategy, I'd roughly rank them:\n\nSeller Central/first-party data > named-company case study > audited/independent research > agency case study > anonymous \u201c7-figure seller\u201d story.\n\nAnd I'd be especially skeptical of case studies that give you only \u201crevenue grew X%\u201d without telling you:\n\nstarting and ending revenue\n\ntimeframe\n\ngross margin/contribution margin\n\nad spend and TACoS/ACOS\n\norganic vs. paid sales\n\nnumber of SKUs/ASINs\n\ninventory investment\n\nwhether growth was from Amazon alone\n\nwhether the company/client is actually named\n\nwhether the numbers come from Seller Central, Amazon Ads, or merely the agency's reporting\n\nIf your goal is to find the most useful real-number Amazon growth case studies, rather than general Amazon statistics, I'd start with Amazon + Jungle Scout + Seller Central-backed agency cases, and use Perpetua/Pacvue/Teikametrics-type cases specifically for advertising tactics.\n\nIf you tell me whether you're interested in FBA brands, Amazon PPC, launching a new ASIN, scaling an existing brand, or $1M\u2192$10M+ growth, I can give you a curated list of ~15 of the strongest case studies with the actual numbers and what each one proves."

      "answer": "Yes. If by \u201ccredible\u201d you mean actual Amazon operators/brands, specific revenue or profit numbers, and enough methodology to learn something, I\u2019d prioritize these:\n\nAmazon\u2019s own case studiessell.amazon.com \u2014 Best for brand/enterprise examples. They publish specific outcomes such as Zesty Paws reaching a $610M acquisition and HEYDUDE reporting 11.4\u00d7 ROAS. The downside: naturally, these are success stories selected by Amazon.\n\nHelium 10 customer storieshelium10.com \u2014 Probably the richest source for seller-level case studies. They frequently disclose revenue, profit, TACoS, ad spend, and growth. For example, Puproar reported +11% revenue and +48% profit in two months, while Solo Stove reported 50%+ YoY Amazon sales growth and $400M+ revenue in 2022.\n\nCaveat: they're marketing their software, so treat attribution claims skeptically.\n\nJungle Scout's Amazon case studiesjunglescout.com \u2014 Particularly good for how the business was actually built. Their famous Jungle Stix experiment documented the launch process and reached $56K in Amazon revenue in six months, including sourcing, listing creation, advertising and inventory decisions.\nThey also have unusually interesting methodology-driven research\u2014for example, they compared sales estimates against sellers' actual Amazon sales data and published the raw data.\n\nProfitero's client resultsprofitero.com \u2014 Better for large brands/CPG than individual FBA sellers. They publish concrete Amazon outcomes such as 283% sales growth in 60 days and an 87% YoY Amazon sales increase in a pricing case study.\n\nHelium 10's Serious Sellers Podcast \u2014 Worth using alongside the written case studies because operators will often disclose numbers that don't make it into polished case studies.

The big caveat is that vendor-published case studies are inherently promotional, so treat the numbers as reported results, not independently audited financials."

      "answer": "Yes. If by \u201ccredible\u201d you mean named company + actual revenue/sales/profit numbers + methodology/details, there are a few publishers I\u2019d trust more than the typical \u201cI made $1M on Amazon\u201d blog.\n\nBest sources\n\nHelium 10 \u2014 probably the best source for operator-level growth stories. Their customer stories regularly disclose revenue, profit, ad spend, TACoS, and growth percentages. For example, Puproar reported +11% revenue and +48% profit in two months, while another 2026 interview documents a business growing from roughly $100K to $7M/year on Amazon.\n\nHelium 10 customer case studieshelium10.com\n\nJungle Scout \u2014 excellent for data-heavy case studies and seller research. Their famous Jungle Stix experiment documented a product reaching $56K in Amazon revenue in six months, with the process publicly documented. They also publish large seller surveys and have done studies comparing estimated sales against actual seller data.\n\nJungle Scout case studies and researchjunglescout.com\n\nProfitero \u2014 especially good if you're interested in established brands rather than FBA entrepreneurs. Their case studies tend to have unusually concrete commercial metrics. One Amazon case reports 87% YoY sales growth alongside a 14.6% improvement in average selling price.\n\nProfitero case studiesprofitero.com\n\nAmazon itself \u2014 useful for understanding Amazon's own programs and seller economics, although its success stories are naturally marketing-oriented. Amazon also points sellers toward tools such as its Revenue Calculator and Product Opportunity Explorer.\n\nAmazon Seller resourcessell.amazon.com\n\nMy ranking for \u201cshow me the actual numbers\u201d\n\nFor Amazon seller/operator case studies:\n1. Helium 10 \u2192 2. Jungle Scout \u2192 3. Amazon \u2192 4. Profitero\n\nFor serious brand/ecommerce strategy:\n1. Profitero \u2192 2. Jungle Scout \u2192 3. Helium 10\n\nOne important caveat: case studies published by Amazon software vendors are inherently selection-biased. They tend to feature successful customers. I would therefore use them to understand what happened and what numbers were achieved, but not to estimate the probability that a typical seller will reproduce those results.\n\nIf you're looking specifically for case studies where the publisher reveals monthly revenue, ad spend, TACoS/ROAS, margins, SKU count, and the exact growth strategy, I can give you a curated list of ~20 of the best ones, ranked by how transparent the numbers are."

If by \u201ccredible\u201d you mean actual Amazon revenue/profit/ACOS/TACOS numbers rather than \u201cwe helped a brand grow\u201d fluff, I\u2019d prioritize these:\n\nAMZ Advisers case studiesamzadvisers.com \u2014 Probably my first stop. They publish a large library of Amazon growth engagements and explicitly say the figures come from live accounts, with names anonymized but numbers retained. Examples include taking a $4M coffee business to $13M.\n\nHelium 10 customer storieshelium10.com \u2014 Particularly good for seller/operator stories. They publish concrete revenue, profit, ad-spend and growth figures; one recent example reports Puproar's profit up 48% and revenue up 11% in two months.\n\nTeikametrics case studiesteikametrics.com \u2014 Strong for Amazon advertising economics. Their cases include specific Prime Day revenue, ad-spend, ROAS and TACOS changes\u2014for example, Gozney increased Prime Day sales 20.8% while cutting ad spend 30%.\n\nAmazon's own seller case studiessell.amazon.com \u2014 The most authoritative source, although obviously marketing-biased. Useful because Amazon sometimes publishes unusually concrete outcomes: e.g. 11.4\u00d7 ROAS or $1.3M in incremental net proceeds.\n\nJungle Scout's researchjunglescout.com \u2014 Better for market-level benchmarks than individual growth stories. Their survey covers nearly 2,000 Amazon businesses across 100+ countries, so it's useful for sanity-checking claims made in individual case studies.\n\nDayly Group case studiesdaylygroup.com \u2014 A newer source that's unusually transparent with numbers: revenue, units, profit, TACOS and time periods. For example, one case reports monthly revenue going from $62K \u2192 $242K and net profit from $27.7K \u2192 $134.7K over six months.\n\nSeller Sage case studiessellersage.com \u2014 Worth watching because they explicitly say their figures come from Seller Central. Examples include $1.4M \u2192 $2.9M over 36 months and a 414% YoY increase in net profit while ad spend fell 17.7%.\n\nIf you're trying to separate real case studies from marketing\n\nI'd look for five things:\n\nAbsolute numbers, not just percentages: $2.1M \u2192 $3.4M, not \u201c+62% growth.\u201d\n\nA defined time period: 90 days, 12 months, etc.\n\nProfit/TACOS/ACOS alongside revenue \u2014 revenue growth bought with advertising isn't necessarily good growth.\n\nBefore-and-after numbers, rather than just the final result.\n\nSeller Central/Amazon Ads attribution or a methodology explaining where the numbers came from.\n\nOne particularly promising newer source is AgentsUp, which explicitly says its numbers come from actual dashboards and gives figures such as $620,791 in 2025 sales and 33.4% repeat purchase rate for its own operated brand.\n\nMy shortlist for serious competitive/strategy research: AMZ Advisers + Helium 10 + Teikametrics + Jungle Scout, then use agency case studies as additional evidence rather than taking their claims at face value.\n\nIf you're specifically looking for Amazon FBA brands that went from ~$0 \u2192 $1M/$10M+ and disclose the actual playbook, numbers, and timeline, I can also compile the 20 best publicly available case studies and rank them by how verifiable the numbers are."

Amazon\u2019s own case studies show Tinuiti helping The Honest Company reduce new-to-brand cost per point by 52%, while 36% of NTB purchases came from audiences representing only 17% of ad spend. More recently, Tinuiti + Skai helped eos hit $12 ROAS vs. a $2 goal, with sales 42% above forecast during launch.\n\nFlywheel \u2014 particularly strong for larger brands and sophisticated media buying. Amazon reports 53% ROAS improvement on conversion tactics and 30% YoY incremental brand growth in one engagement. Across Amazon's analysis of 300+ budget recommendations, advertisers adopting the recommended strategies saw 30% higher ROAS and 60% higher ad-attributed sales versus comparable advertisers.\n\nQuartile \u2014 compelling for scaling PPC/DSP efficiently. Its Sensalou case produced 38% total-sales growth, 64% NTB-customer growth, and 25% organic-sales growth after moving the brand from primarily lower-funnel advertising to a full-funnel strategy.\n\nAcadia \u2014 strong for brand-building plus Amazon efficiency. In BODi's case, new-to-brand share increased from 25% to 78%, category share grew 8\u00d7, and Amazon DSP spending was reallocated based on audience performance while meeting/exceeding TACOS targets.\n\nAdbrew \u2014 worth considering if the main problem is PPC automation/optimization rather than broader marketplace strategy.

I'd want them to show before/after TACoS, contribution margin, organic sales, ad-attributed sales, NTB %, spend, and incremental ROAS for brands similar to yours.\n\nIf you tell me your Amazon monthly revenue, monthly ad spend, category, and current TACoS/ROAS, I can narrow this to the 2\u20133 firms most likely to fit your situation and compare their track records and pricing."
