Viraat Das

Viraat Das is the cofounder and CEO of Exla, a Y Combinator (Winter 2025) startup building AI infrastructure. A former Amazon machine learning engineer who finished his Purdue computer science degree in two and a half years, he first shipped an SDK that squeezes large transformer models onto edge hardware like NVIDIA Jetsons, then aimed the company at Libra, an always-on AI site reliability engineer that reads production logs, traces failures to the deploy that caused them, and opens fix pull requests while the team sleeps.
