The ranking

Share = the percentage of the 55 responses that named the firm. Bars are drawn to the same scale across the table and repeat the number in the share column. Firms within a tier are not distinguishable at this sample size and are listed in no particular order.

Why the tiers fall where they do

Tier 1 holds Spencer Stuart, named in 38 of 55 ChatGPT responses (69.1%). No other firm in this sample comes close enough to be grouped with it.

Tier 2 holds Russell Reynolds Associates, Heidrick & Struggles, Egon Zehnder and Korn Ferry, named in 19 to 27 of 55 responses (34.549.1%). The sample does separate these firms from the tier above: the difference from the leading group is larger than the margin of error, which is what puts them in a tier of their own.

Tier 3 holds Stanton Chase, DHR Global and ZRG Partners, named in 5 to 12 of 55 responses (9.121.8%). The sample does separate these firms from the tier above: the difference from the leading group is larger than the margin of error, which is what puts them in a tier of their own.

Tier 4 holds ECA Partners and Odgers, named in 3 to 3 of 55 responses (5.55.5%). The sample does separate these firms from the tier above: the difference from the leading group is larger than the margin of error, which is what puts them in a tier of their own.

The test is McNemar’s at 95%, applied against the same 55 responses for every firm. The full reasoning, and what happened when we ranked one-to-N instead.

What the sample shows

Spencer Stuart leads on its own, named in 38 of the 55 responses to this question (69.1%).

210 firms were named at least once across the sample. 10 of them cleared the threshold of 2 responses and appear above; the rest were named once and are inside the noise.

How to read this

Firms are grouped into tiers, not ranked one to fifteen. A tier holds every firm whose 95% confidence interval overlaps the leader's, which is a long way of saying the sample cannot tell them apart. Order within a tier is arbitrary — read the counts, not the position.

Share is the percentage of responses that named the firm — not a quality score. A firm scoring low here may be excellent and simply under-written about online, which is a finding about its visibility rather than its work.

The same question was asked repeatedly because AI assistants do not answer identically twice. A single response would tell you almost nothing.

What this measurement does not tell you

  • It is not a quality ranking. Share reflects how much has been written about a firm online, which is what an AI assistant reads. A capable firm nobody writes about scores low here.
  • It is a reading from a date range, not a permanent standing. This sample was collected August 11, 2026–August 19, 2026; models change and so do their answers.
  • It covers ChatGPT only. Other assistants answer differently, and we do not extrapolate across engines we have not measured.
  • Order within a tier is arbitrary. Read the counts, not the position. Why we use tiers.
