Dedalus Labs
Every enduring company begins with a single, stubborn frustration (ideally felt by the founders themselves). For Dedalus Labs, it was this: building and deploying MCP servers shouldn’t be this hard.
When the founders (Cathy Di and Windsor Nguyen) began experimenting with AI agents, they kept encountering the same bottleneck. Everyone they talked to (and most of the MCP subreddit) were spending hours fighting with AWS and GCP configs just to get something live.
A week into YC’s S25 batch, Dedalus built a hosting solution that deployed MCP servers seamlessly: no Dockerfiles, no YAML, no endless cloud debugging. Cloud hosting was just the tip of the MCP iceberg: they then released their agent SDK (Python TypeScript, and Go), which supports model handoffs and tool chaining right out of the box, significantly lowering the activation energy required to build complex agents.
Throughout our conversations and whiteboard sessions, we realized very quickly that Cathy and Windsor are special founders: they are obsessed with developer experience and it shows in the quality of their code, design decisions, and numerous Collison installations they’ve performed at hackathons and office hours.
Dedalus’s belief in MCPs is foundational. In their view, MCP is the language of agents. It’s the standard that allows AI systems to call tools, access data, and execute actions predictably. Products that expose themselves as MCP servers become accessible not only to users but to the growing ecosystem of autonomous applications. As more of the world transitions toward AI autonomy (e.g. agentic commerce), the addressable market isn’t just human beings anymore—it’s also all agents working on their behalf.
In that world, exposing your service as an MCP endpoint isn’t optional; it’s inevitable. And Dedalus Labs is building the infrastructure to make that shift as easy as possible for everyone. We’re excited to be partnering with them alongside our friends at Y Combinator and Kindred Ventures.
