Prelude, founded in 2023 and based in Paris, provides trust and identity-verification infrastructure that combines phone verification, device integrity, carrier data, and behavioral signals into a risk engine to stop fraudulent account creation, bot traffic, and account takeover during onboarding. It is moving beyond single-purpose SMS and OTP verification to a full-stack platform (Auth API and Intel API) meant to replace brittle CAPTCHA and SMS-only flows.
