Israeli cybersecurity startup Oak has emerged from stealth mode with $60 million in seed funding to build an AI-powered Identity Operating System.
The investment round was co-led by Accel, Greylock Partners, and CRV, with additional support from Hetz Ventures, AlphaDrive Ventures, and angel investors.
Founded in late 2025, Tel Aviv- and San Francisco-based Oak has built a platform that unifies identity governance within a single, continuously updated control plane.
Already generally available, Oak’s Identity Operating System aims to replace legacy identity governance and security tools with a single solution covering all human, AI, and machine identities across an organization’s environment.
The platform connects to an organization’s applications across cloud, on-premises, SaaS, and homegrown systems to build connectors within hours, understanding each identity based on raw evidence instead of static records.
By creating a map of each identity’s access against what it uses, Oak’s platform provides identity governance throughout the entire lifecycle, complemented by AI-driven real-time risk decisions and remediation.
Oak was co-founded by Shai Morag (Chief Executive Officer), who previously founded Integrity-Project (acquired by NVIDIA’s Mellanox), Secdo (acquired by Palo Alto Networks), and Ermetic (acquired by Tenable); and Tal Marom (Chief Product Officer), who previously led product teams at Tenable and Salesforce.
“We spent months speaking with more than 100 CISOs and IAM leaders, and they all share the same problems of running too many disconnected tools, being unable to see how access is used, and having no way to govern AI agents,” Marom said.
“Just as CNAPP consolidated the fragmented cloud security stack, identity is now at that same inflection point, and Oak is designed to be the platform that brings it all together and turbocharges the security teams defending the enterprise,” Marom added.
