What AI assistants actually recommend when buyers ask about b2b lead generation tools — measured on a rolling 4-week window across 5 engines, published as open data.
Updated 2026-09-17 · 63 sampled answers · rolling 4-week window · methodology
Rankings are measured from sampled AI answers — never editorial, never paid. Orbator builds AI-visibility tooling; when Orbator itself appears in any category, it is measured by the same rules as everyone else.
Measured by Orbatormethodology owner Henrik Tellewindow ends Sep 17, 2026
Sample: 63 AI answers · Window: Aug 20, 2026 – Sep 17, 2026 (4-week rolling) · trend vs prior 4 weeks (29 answers)
Samples by engine: GEMINI 14 (last run Sep 4, 2026) · CHATGPT 14 (last run Sep 4, 2026) · CLAUDE 14 (last run Sep 5, 2026) · PERPLEXITY 14 (last run Sep 4, 2026 — stalest) · GROK 7 (last run Sep 4, 2026)
How these numbers are made: sampling design · prompt provenance · what counts as a mention · what we cannot see
On the record: This ranking is frozen as a dated snapshot every day. View this category's history to see what entered and left the ranking and when, or read what the engines actually said on a given day.
Across 63 sampled AI answers from 5 engines, ZoomInfo is recommended most often — appearing in 79.4% of recommendations, followed by Apollo AI (74.6%) and Cognism (66.7%).
This is a measurement of share of voice across 5 AI engines — not an editorial pick. See the full ranking below.
Orbator asked Gemini, ChatGPT, Claude, Perplexity and Grok buyer questions about b2b lead generation tools and sampled 63 answers between Aug 20, 2026 and Sep 17, 2026. Recommendation share counts the answers that recommended or listed a product, so a passing mention or a warning adds nothing to it. A category publishes once it holds at least 20 independently sampled answers in the window. Read the full methodology or download this ranking as CSV.
Buyer prompts in this window split across seven questions, from outbound prospecting shortlists to verified contact data and enrichment quality. The two largest intents each carry 18 runs. In best_in_category (18 runs), Apollo AI and Cognism both led at 88.9%. In problem_solving (18 runs), ZoomInfo led at 83.3%. Alternatives ran 9 times, with Apollo AI recommended in 88.9% of them. Comparison ran 9 times, led by ZoomInfo at 55.6%. The recommendation intent ran 9 times, with Apollo AI, Clay and ZoomInfo each recommended in 100%.
Four of the five top products over-index on the same alternatives prompt, so an affordability framing pulls a wide set rather than a narrow one. Two pricing facts exist. Apollo AI lists Starter: Free, last verified 2026-09-05. Clay lists Launch: $167 a month (free tier available), last verified 2026-09-05.

Reading the numbers: Share is a point estimate on 63 sampled answers, so each row also shows its 95% CI — the Wilson score interval around that share. When two products' intervals overlap, the gap between them isn't statistically meaningful at this sample size. First pick is the share of a product's recommending answers where it was named first, which separates “always mentioned” from “usually the top recommendation”. Full methodology.
