50M+ websites requiring age-gated compliance globally
The Problem

Governments worldwide are rapidly mandating strict age verification on websites and platforms, rendering simple self-attestation illegal. The current alternatives—uploading passports, government IDs, or biometric face scans to third-party databases—create massive privacy risks, frequent data breaches, and a de facto surveillance infrastructure that users and platforms alike find unacceptable.

Potential Solution

A drop-in API gateway that lets websites verify a visitor's age using zero-knowledge cryptographic proofs. Users complete a one-time identity verification through a trusted credential issuer, then receive a reusable cryptographic token that proves only 'this person is 18+' without revealing name, face, or ID number. Platforms integrate a lightweight SDK and never touch or store personal data, eliminating breach liability while satisfying regulatory requirements.

Why Now?

A wave of enforceable age-verification laws—the UK Online Safety Act, the US Kids Online Safety Act (HR 7757), and similar EU and Australian mandates—are creating immediate legal obligations for millions of websites. Platforms face compliance deadlines with no privacy-respecting solution available at scale, making this an urgent infrastructure need.
