Persona

Persona runs identity verification for online platforms, matching a user's selfie against government ID with facial-recognition and liveness checks to 'reveal who is behind each action.' As new age-verification laws spread in 2025–2026, it became a dominant vendor behind age checks for platforms reportedly including Reddit, Roblox, and OpenAI, and added AI deepfake-and-spoof detection. Marketed for fraud, KYC, and age assurance, it normalizes routine biometric capture across the consumer internet — a $2 billion company (2025) backed by Founders Fund.
