Verbatim evidence the judge attached to positive labels.

“Choose Bombora if: You have a functioning RevOps and activation stack and primarily want a widely integrated external intent feed.” GPT-5.6 Sol · Intent data · comparative prompt · first choice
“the best all-around choice is usually Bombora if you want the strongest *raw third-party intent signals*” Perplexity Sonar Pro · Intent data · direct prompt · first choice
“Bombora (intent data) + G2 Buyer Intent (category/competitor signals), fed into your existing CRM/MAP.” Claude Opus 4.8 · Intent data · paraphrase prompt · first choice
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.
“Avoid enterprise platforms like 6sense, Demandbase, and often Bombora if budget is tight” Perplexity Sonar Pro · Intent data · budget prompt · hard negative
“a caution about expectations, not ethics ... independent reviews flag real limits: weekly (not real-time) refresh, US-centric coverage, account-level only ... around 81%” Claude Opus 5 · Intent data · negative prompt · soft negative
“enterprise providers like 6sense, Demandbase, ZoomInfo, or Bombora has cost tens of thousands of dollars per year” Gemini 3.1 Pro · Intent data · budget prompt · soft negative
“6sense, Bombora or Demandbase | More sophisticated, but generally difficult to justify on a limited budget” GPT-5.6 Sol · Intent data · budget prompt · soft negative
Claiming is free and changes nothing in the data. A claimed page gets a verified contact who is told when each edition publishes; the right to propose corrections to the vendor table, meaning names the judge wrote that should or should not read as Bombora, applied by version and listed in the change log; and a logo and one-line description supplied by the vendor and marked as such.
It does not get any change to labels, shares or quadrants, any preview, or any say over which quotes appear. Sponsorship is separate: a sponsor funds categories or buyer dimensions and is named on what it funded, and the rules are the same for every sponsor.
