Fourteen AI models were asked for customer data platform six ways each, on behalf of a small, a mid-market and an enterprise B2B company: 252 answers, in which a judge labeled 71 products. Eight of them carry at least 10 labels and a first choice, and are ranked. This guide walks the top eight in the order the mid-market standing puts them, with what the models said for and against each, in their words. Segment leads at 50% of first choices, a clear leader.

## Questions the record answers

**Which customer data platform do AI models name first most often?** Segment, in 50% of first choices for a mid-market B2B company in the November 2026 Edition, from 70 labels. The index calls that a clear leader.

**Does the answer change with the size of the company?** Small business: Segment at 41%. Mid-market: Segment at 50%. Enterprise: Salesforce Data Cloud at 50%. Each standing is computed within its segment and never pooled.

**Which framing changes the answer?** The direct, paraphrase, budget and scale framings count toward share. The product named first differs by framing: direct Segment; paraphrase Segment; comparative ActionIQ; budget-constrained RudderStack; scale-constrained Segment; negative Amperity. The table above has the counts.

**How stable is one answer?** The repeat measurement is published with the next edition.

**Where do the answers come from?** Fourteen of the fourteen models return sources. Their 74 answers here cite 805 pages; the sites cited most are g2.com, cdp.com, zapier.com. The category page lists them all.

**Can a vendor pay to be on this list?** No. A product is on the record because a model named it. A vendor can claim its page, propose corrections to the vendor table and be told when its standing moves; it cannot change a label, a share or a rank, and the publisher's conflicts are disclosed on the method page.
