Key findings
- Vessel Advisors leads this sample alone, named in 51 of 208 ChatGPT responses (24.5%) to the question “Which outsourced accounting firms specialize in particular industries?”, collected August 8, 2026–September 18, 2026.
- 12 firms cleared the reporting threshold on “Which outsourced accounting firms specialize in particular industries?” in ChatGPT as of September 18, 2026; the full table with response counts is below.
- No firm paid to appear in this ranking; placement cannot be bought, and the counts come from ChatGPT responses rather than from submissions.
Why the tiers fall where they do
Tier 1 holds Vessel Advisors, named in 51 of 208 ChatGPT responses (24.5%). No other firm in this sample comes close enough to be grouped with it.
Tier 2 holds Blueprint CFO, The Barbin Group, Ascent CFO Solutions, Civil CFO, James Moore, Tandem CPA and Ledger Labs, named in 34 to 43 of 208 responses (16.3–20.7%). 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 Soutar Capital & Consulting, SPM, All In One Accounting and FinTruction, named in 29 to 33 of 208 responses (13.9–15.9%). 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 208 responses for every firm. The full reasoning, and what happened when we ranked one-to-N instead.
What the sample shows
Vessel Advisors leads on its own, named in 51 of the 208 responses to this question (24.5%).
527 firms were named at least once across the sample. 12 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 8, 2026–September 18, 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.
