Ethan Byrd is the Founder of Primitive, a Y Combinator-backed startup building the communication infrastructure needed for fully autonomous AI agents.

Ethan studied at the Georgia Institute of Technology and built deep engineering expertise across Microsoft, AWS, Facebook, and Google before launching his first venture.

A serial founder at the frontier of AI infrastructure, Ethan brings a rare combination of big-tech engineering scale and startup execution, having previously co-founded Actual AI.

At Primitive, Ethan is building the communication layer that enables AI agents to talk to each other, to humans, and to external systems in real time and at scale.

Accepted into Y Combinator's Spring 2026 batch, Primitive is actively growing its founding team in San Francisco and positioning itself as foundational infrastructure for the autonomous agent era.
