Self is a San Francisco–based identity-solution provider that uses zero-knowledge (ZK) cryptography to verify characteristics such as personhood, age, and country of residence while keeping underlying data private. The platform supports privacy-preserving identity checks for users in more than 174 countries and is already integrated by Web2 and Web3 partners including Google Cloud, Aave, and Velodrome. It was created by Celo contributors Rene Reinsberg, Marek Olszewski, and CEO Eric Nakagawa after acquiring the OpenPassport project. By combining ZK proofs with a user-friendly experience, the company aims to foster a more secure, human-first internet. Fresh capital is earmarked for expanding engineering and operational capacity to accelerate product development and global reach. No revenue or user counts were disclosed, but the breadth of geographic coverage underscores early traction. The firm positions itself as critical infrastructure for compliance, onboarding, and reputation in decentralized and traditional applications alike.
