Rhys Sullivan is the Founder of Executor, an open source MCP gateway and integration management layer that enables AI agents to connect to any service, API, or data source.

Rhys studied at Champlain College and built his engineering career at industry-leading companies including Vercel, Microsoft, Raven Software, and Epic Games, where he honed deep expertise in developer tooling and product engineering.

Rhys is a recognized voice on agent UX and product engineering primitives, having spoken at React Miami 2026 and featured on the Chats with Kent C. Dodds podcast, advocating for composable, safe, and well-designed agent systems.

Executor was accepted into Y Combinator's Summer 2026 batch and its open source GitHub repository has already amassed over 2,800 stars, reflecting strong traction in the developer and AI agent community.

Executor's open source MCP gateway lets teams configure integrations once and use them across any agent client, supporting MCP, GraphQL, and OpenAPI specs, removing fragmentation in the fast-growing AI agent tooling space.
