Which outsourced accounting firms specialize in particular industries?

Fractional CFOs by Industry: What The Shortlist Report Finds

2 firms lead, appearing in 19.0–22.5% of 378 AI responses. The sample cannot separate them, so we do not pretend it can.

Two firms lead

Vessel Advisors and The Barbin Group come up most often here. They are close enough together that the order between them is not worth reading anything into.

Based on 378 ChatGPT responses to this question, collected August 8, 2026–October 29, 2026. Firms are counted once per response. How we measure.

Which firm for which industry

12 of the 12 firms named an industry in the way ChatGPT described them, and they are grouped below in those words. A firm that named several industries appears under each of them, so the groups add up to more than 12. This is a reading of the descriptions rather than a second measurement — the counts, and every firm, are in the table.

Key findings

  1. Vessel Advisors and The Barbin Group lead this sample, each named in 19.0–22.5% of 378 ChatGPT responses to the question “Which outsourced accounting firms specialize in particular industries?”, collected August 8, 2026–October 29, 2026.
  2. The gaps between Vessel Advisors and The Barbin Group are inside the margin of error at 378 responses, so The Shortlist Report groups them in one tier rather than ranking them against each other.
  3. 12 firms cleared the reporting threshold on “Which outsourced accounting firms specialize in particular industries?” in ChatGPT as of October 29, 2026; the full table with response counts is below.
  4. 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 and The Barbin Group, named in 72 to 85 of the 378 ChatGPT responses. They are grouped rather than ranked because the gaps between them are inside the margin of error at this sample size — one extra mention would reorder them, so an order would be reporting noise as a finding.

Tier 2 holds Blueprint CFO, Ascent CFO Solutions, Ledger Labs, Civil CFO, Tandem CPA and James Moore, named in 55 to 69 of 378 responses (14.6–18.3%). 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, FinTruction, US Fractional CFO and LedgerGurus, named in 45 to 53 of 378 responses (11.9–14.0%). 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 378 responses for every firm. The full reasoning, and what happened when we ranked one-to-N instead.

What the sample shows

2 firms lead this question: Vessel Advisors and The Barbin Group. They appear in 19.0–22.5% of the 378 responses. The gaps between them are inside the margin of error at this sample size, so they are listed together rather than ranked against each other.

771 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–October 29, 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.
