Shares here are read over the models both editions asked, so they can differ by a point or two from the standing above, which counts every model in this edition.
The floor is 11 points of share, measured: how far the models move a leader on their own when the same questions are asked twice with nothing changed. A larger change is movement; a smaller one is noise, and both are shown. Movement is read over the twelve models both editions asked; GPT-6 Luna, Muse Glimmer 30B joined this edition and are in the standing but not yet in the comparison.

Verbatim evidence the judge attached to positive labels.
“RB2B is particularly well-suited for early-stage B2B SaaS or services companies with US-only focus, sales-driven activation, and budget constraints, offering a free tier” Claude Haiku 4.5 · Identity · budget prompt · first choice
“I'd recommend RB2B if you have meaningful website traffic and want person-level identification” DeepSeek V4 Flash · Intent data · budget prompt · first choice
“If you have zero budget but some website traffic: Set up RB2B (for US traffic)” Gemini 3.5 Flash · Intent data · budget prompt · first choice
“the practical stack is usually Apollo.io or RB2B for coverage” Muse Glimmer 30B · Intent data · budget prompt · first choice
Verbatim evidence attached to negative labels. A warning on a product with few labels is a warning; on a product with many, it is one voice among them.
“don't provide genuine A/B testing or optimization functionality” DeepSeek V4 Flash · Experimentation · negative prompt · hard negative
Citations exist only for the models that return a source list, five of the fourteen in this edition, so these counts come from 95 of the 97 answers that named RB2B and are not a share of its labels.
265 of the 305 domain citations in answers naming RB2B came from somebody else's page.
Pages are listed as the models cited them.
Search figures are US estimates from DataForSEO, read September 28, 2026; AI search demand is its modeled, directional estimate, not a count of queries to any assistant. The answers are this edition's. Two measurements side by side: neither is read as the cause of the other.

Every page rb2b.com exposes, subdomains included. Kind is read from the address and title. The last 90 days, the latest date and the twelve months count pages by when they were published, from the site's feeds, a date in the address, or the page's own publication date, read from up to a hundred of its most recently changed pages; a page that says only when it last changed is counted in its kind but not in when, so the recent counts are a floor, and a kind none of whose pages gives a publication date reads undated. Read September 29, 2026.

What RB2B's own pages state, read September 28, 2026: rb2b.com, rb2b.com/pricing, rb2b.com/security, rb2b.com/integrations. A claimed page can correct any of them.
Claiming is free and changes nothing in the data. A claimed page shows a verified contact who is told when each edition publishes and when RB2B's standing changes by more than the noise floor; the right to propose corrections to the vendor table, meaning names the judge wrote that should or should not read as RB2B, applied by version and listed in the change log; and a one-line description supplied by the vendor and marked as such.
A new claim receives the current edition's vendor brief for RB2B by email, built from the raw record of the edition. It shows:
