Oak
An unusually well-funded seed-stage identity platform, co-led by three top-tier VCs, already generally available with enterprise customers at launch.

Launched from stealth with a generally-available platform already deployed at enterprise customers, unusually mature for a seed-stage company.
Very early stage despite GA claims; independently verified deployment scale was not found.
Raised an unusually large $60M seed round in July 2026 co-led by Accel, Greylock, and CRV.
Unifying human, machine, and AI-agent identity governance into one control plane challenges the fragmented legacy IAM/IGA stack.
Too early for independent efficacy data; GA and deployment claims are company-stated.
Unified identity governance across human, machine, and AI-agent identities is an increasingly central and durable enterprise security need.
Why CISOs Should Care
Oak gives CISOs a single, AI-native control plane that governs every identity in the organization -- human, machine, or AI agent -- replacing the fragmented stack of legacy IAM and identity governance tools.
What Makes It Different
Oak positions its platform as an 'Identity Operating System' rather than a point IAM/IGA tool, aiming to unify identity governance across all identity types (human, machine, agent) in one continuously updated control plane.
The Matrix Verdict
50/100 — INCREMENTAL INNOVATOR
An unusually well-funded seed-stage identity platform, co-led by three top-tier VCs, already generally available with enterprise customers at launch.
Editorial Note: Claims vs. Verified Findings
Company states the platform is 'already generally available and deployed across enterprise customers' at stealth exit; specific customer count was not independently disclosed.
