Atai Barkai
Atai Barkai is the co-founder and CEO of CopilotKit, the Seattle-based open-source company building the interface layer between humans and AI agents. He and his brother Uli created AG-UI, an open protocol now adopted by Google, Microsoft, Amazon, Oracle, and major AI frameworks, with millions of weekly downloads. A physicist by training who pivoted into developer infrastructure at Meta and Doximity, Barkai bet early - during the GPT-3.5 era - that humans and agents would build software together, and is now turning that bet into the standard for how AI agents talk to the apps people actually use.
