What We Do
Dedalus Labs is a San Francisco-based startup building the compute substrate for AI agents — the infrastructure layer for agentic AI. Its product, Dedalus Machines, lets developers run long-lived, stateful agents on full Linux virtual machines that launch in under 250 milliseconds with zero cold starts, persistent filesystems, and billing based only on active compute. Founded in 2025 by Cathy Di and Windsor Nguyen and backed by Y Combinator (Summer 2025 batch), it also offers an MCP gateway service.
