What the models said for it

Verbatim evidence the judge attached to positive labels.

“For most mid-market B2B companies, PartnerStack offers the best combination of B2B-specific features, partner marketplace access, and scalability.” Mistral Small · Affiliate · direct prompt · first choice
“PartnerStack if you're a B2B software company and want a partner ecosystem platform that's strong on scaling recruitment, management, and payouts” GPT-5.4 mini · Channel marketing · paraphrase prompt · first choice

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.

“Trustpilot rating of 2.0/5 driven by payout delays, withheld commissions, and sudden account closures” DeepSeek V4 Flash · PRM · negative prompt · hard negative
“Trustpilot rating of only 2.0/5 ... Sudden account bans without clear explanations” Mistral Small · PRM · negative prompt · hard negative
“It is not built for traditional reseller, distributor, or co-selling channels” Gemini 3.5 Flash · PRM · negative prompt · hard negative

What carried it into the answer

The sites and pages cited by the answers that named PartnerStack. 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 59 of the 384 answers that named PartnerStack 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 PartnerStack'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 PartnerStack, 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 partnerstack.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.
