In recent weeks, we’ve already seen AI agents go rogue or leak sensitive data due to weak identity infrastructure – a preview of what happens when autonomy outpaces trust. There’s a structural mismatch between how our systems authenticate and how agents actually behave. @KeycardLabs is building the missing trust fabric for this new world. Keycard issues dynamic, identity-bound, task-scoped tokens: cryptographic “keycards” that carry verifiable proof of who the agent is, what it is allowed to do, and for whom. We’re investing in Keycard to build the identity layer for the agent economy. Founders @ianlivingstone, @Matt_Creager, and @jaredhanson combine deep expertise in infrastructure, developer-first design, and online identity. We’re thrilled to be backing them.(a16z)
