What the models said for it

Verbatim evidence the judge attached to positive labels.

“Prioritize vendors like LiveRamp, Hightouch, Acxiom, or mParticle, which suit mid-market needs” Grok 4.1 Fast · Identity · scale prompt · alternative

“Acxiom (Real Identity) - Precision-focused for large brands.” Grok 4.1 Fast · Identity · comparative prompt · alternative

“Enterprise scale: LiveRamp, Acxiom, or Experian” Kimi K2 · Identity · comparative prompt · alternative

“2. Acxiom ⭐ *Best for large-brand precision*” Mistral Small · Identity · comparative prompt · alternative

And against it

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.

What carried it into the answer

The sites and pages cited by the answers that named Acxiom. A fact about retrieval, not a lever on the model.

Citations exist only for the models that return a source list, four of the twelve in this edition, so these counts come from 4 of the 37 answers that named Acxiom and are not a share of its labels.

Claim this page

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 Acxiom'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 Acxiom, applied by version and listed in the change log; and a one-line description supplied by the vendor and marked as such.

It does not get any change to labels, shares or verdicts, any preview, or any say over which quotes appear. A verification link goes to your work email; an address at acxiom.com is approved on the spot, any other address is reviewed by hand.

Your name and company appear on the claimed page, or the company alone if you ask below. A title and a LinkedIn address appear there too if you give them, and are left off if you do not. Your email address is never published.
