Why the tiers fall where they do
Tier 1 holds Marknology, named in 21 of 35 ChatGPT responses (60.0%). No other firm in this sample comes close enough to be grouped with it.
Tier 2 holds Seller Sage, Clearsight Consulting, Seller Adventures, SupplyKick, Amplivus, Sellers Umbrella, Chief Marketplace Officer, PPC Jumpstart and Seller Accel, named in 6 to 9 of 35 responses (17.1–25.7%). 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.
The test is McNemar’s at 95%, applied against the same 35 responses for every firm. The full reasoning, and what happened when we ranked one-to-N instead.
What the sample shows
Marknology leads on its own, named in 21 of the 35 responses to this question (60.0%).
83 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 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.
