Keycard

Keycard builds identity and access infrastructure for AI agents, helping developers connect agents to services while security teams govern their actions. Keycard for Coding Agents applies runtime policies and scoped credentials across laptops, sandboxes, and CI environments. Keycard for Multi-Agent Apps gives developers Python and TypeScript SDKs for agents that collaborate, call external services, and connect to APIs. Both were introduced in early access in 2026.

The founders are CEO Ian Livingstone, Matthew Creager, and Jared Hanson, the creator of Passport.js. Keycard’s technical approach ties authorization to the user, agent, device, and task at execution time. Its multi-agent platform uses OAuth 2.0 Token Exchange to narrow permissions through delegation chains, with credentials held in memory and expiring when the session closes. Identity-linked telemetry lets teams investigate actions and revoke access. Keycard acquired Anchor.dev in 2026, adding certificate-based identity expertise to its coding-agent security work.

Keycard emerged from stealth in 2025 with $38 million in funding: an $8 million inception round co-led by boldstart and Andreessen Horowitz, followed by a $30 million Series A led by Acrew Capital. Chime was using Keycard’s platform in production in 2026.
