Why the tiers fall where they do
Tier 1 holds US Fractional CFO Alliance, Tandem CPA, Vessel Advisors, Blueprint CFO, Civil CFO, Gheen CPA, KLO Solutions, SPM – The Construction CFO, The Barbin Group, Acculink CPA, All In One Accounting and Barta Business Group, named in 4 to 7 of the 25 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.
The test is McNemar’s at 95%, applied against the same 25 responses for every firm. The full reasoning, and what happened when we ranked one-to-N instead.
What the sample shows
12 firms lead this question: US Fractional CFO Alliance, Tandem CPA, Vessel Advisors, Blueprint CFO, Civil CFO, Gheen CPA, KLO Solutions, SPM – The Construction CFO, The Barbin Group, Acculink CPA, All In One Accounting and Barta Business Group. They appear in 16.0–28.0% of the 25 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.
89 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; 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.
