What the models said for it

Verbatim evidence the judge attached to positive labels.

“Prospeo is the safest budget-first recommendation from the results for B2B use cases” Perplexity Sonar · Identity · budget prompt · first choice

“For most mid-sized B2B companies, I recommend starting with Prospeo” Mistral Small · Identity · paraphrase prompt · first choice

“Focuses on reducing "fake" demos and ensuring follow-up lands on real human inboxes. Good for outbound-heavy motions.” Qwen 3.7 Flash · Scheduling · scale prompt · alternative

“They offer an introductory free plan (including up to 75 email resolutions/month) with low-cost scaling tiers.” Gemini 3.5 Flash · Identity · budget 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.

No model argued against it.

What carried it into the answer

The sites and pages cited by the answers that named Prospeo. 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 53 answers that named Prospeo and are not a share of its labels.

Is this your product?

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 Prospeo'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 Prospeo, 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 prospeo.io 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.
