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.

Morgan Beller is a General Partner at NFX, the seed-stage venture firm known for backing network-effects businesses. Before VC, she co-founded Facebook's Libra (later Diem) digital currency project at age 25, making her one of the most consequential figures in crypto policy history. A Cornell statistics graduate, she cut her teeth at Andreessen Horowitz before stints at Medium and Facebook, where her geopolitical alarm about China's digital currency ambitions drove her to attempt something audacious: rebuild global money on a blockchain. She now backs founders in crypto, fintech, AI, and space from San Francisco.
