About Proof of Human
Proof of Human, PBC (formerly Roundtable AI) provides a human verification API that analyses behavioral signals such as typing, mouse movement and scrolling to detect bots and AI agents. The product runs silently in the background without CAPTCHAs and is integrated through a JavaScript snippet. It also publishes session reports that explain the signals behind each result.
The company sells its verification to organisations in market research, financial services, and ticketing and live events. Its market research offering targets panel quality and fraudulent survey completions. The website states that the platform processes millions of sessions each month.
The company lists an office at 251 Post Street, San Francisco, and its open roles are based in San Francisco, covering sales, engineering and go-to-market. It publishes research on bot detection benchmarks against AI agents and CAPTCHAs.
