Keycard has launched with $38 million in funding. The company helps businesses secure their artificial intelligence agents.

The capital combines an $8 million seed round and a $30 million Series A investment.

Traditional security methods often give users broad access to applications. This approach is risky for AI agents. An agent with too many permissions might perform unintended or harmful actions. This creates a significant security challenge for companies deploying AI. Keycard's platform provides granular, per-task access controls. It limits an AI agent to only the specific actions needed for its job. This prevents the agent from operating outside its intended scope.

The system also quickly revokes permissions after a task is complete. The platform creates tamper-resistant logs of all agent activity. It integrates with a company's existing systems without changing the agent's code.

Keycard will use the new capital to hire engineers and expand its product features.

Andreessen Horowitz, boldstart, and Acrew Capital led the investment rounds.
