Keycard builds identity and access infrastructure for the agent‑native era, enabling organizations to run AI agents in production with real‑time, contextual authorization and audit. The platform provides in‑band guardrails, short‑lived machine identities, and dynamic, policy‑driven access for mixed human–agent workflows, so developers, platform, and security teams can ship agentic applications with confidence. Keycard offers SDKs and APIs, graph‑based tooling, and developer‑first workflows to model, observe, and modify agent behavior without code changes at runtime. The company’s mission is to unlock the agent economy by delivering secure, scalable foundations for trusted autonomous systems. Engineering work spans distributed systems, platform reliability, and UI that makes complex identity graphs understandable. Keycard operates as a remote‑first, small team with a culture of ownership, iterative delivery, and high standards for security and operability, and emphasizes instrumentation, policy transparency, and zero‑trust principles.
