Yet legacy identity tools were built for a world of human users, static environments, and disconnected systems. Today, organizations must govern a rapidly growing universe of human, machine, non-human, and AI agent identities. Oak rewires enterprise identity and access management with a unified, continuously updated platform built AI-native from the ground up. Our AI connector framework reaches any application, across cloud, SaaS, on-prem, and homegrown environments, and builds a live identity graph from raw evidence. By understanding the access every identity holds and how that access is actually used, Oak enables real-time risk decisions, lifecycle governance, and root-cause remediation. Founded by cybersecurity veterans Shai Morag and Tal Marom, Oak is backed by Accel, Greylock Partners, CRV, Hetz Ventures, and AlphaDrive Ventures. One operating system. Every identity. Built for what comes next.
