About Tools for Humanity

Tools for Humanity builds a decentralized identity protocol anchored in biometric verification through a global network of physical verification points (orbs). The product surfaces through a mobile app (World App) and serves users and developers seeking privacy-preserving identity credentials. The company operates across nine countries and maintains in-house teams for orb deployment, regional operations, and regulatory navigation. Core technical foundations include zero-knowledge cryptography, blockchain settlement (Ethereum/OP Stack), and distributed mobile clients. The organization is scaling both the physical network (kiosk installation, orb operator management) and the protocol layer, with significant investment in legal and security infrastructure to manage privacy compliance and regulatory risk.
