Reprompt
Reprompt builds AI agents for location data. Mapping companies like Foursquare, TomTom, and Radar use its agents to keep points-of-interest and business records current - verifying hours, status, ownership, and dozens of other attributes by cross-referencing web, social, government, and news sources. Founded in 2024 by ex-Mapbox and ex-Robinhood operators, the company turns work that once took weeks of manual research into runs that finish in under an hour.
Truthset
Truthset is an Oakland-based data intelligence company that validates the accuracy of consumer data used in marketing and advertising. Its patented TruthScore methodology assigns a 0-100% likelihood that any given data attribute about a person is actually true, letting brands, agencies, and data providers buy and activate audiences rated by accuracy instead of guessing. Truthset explicitly does not sell data or act as a broker - it positions itself as an independent arbiter of truth for a market where consumer data can carry up to 60% error.
Noyo
Noyo is a San Francisco-based benefits data platform that uses APIs and AI to connect insurance carriers, benefits administration software, and HR teams. It turns the slow, error-prone exchange of employee benefits data into real-time, automated connections, eliminating manual data entry and coverage-impacting errors across the benefits ecosystem.
