Sriram Krishnan, a key AI adviser to President Donald Trump who left the White House in June, is raising an AI-focused venture fund targeting about $500 million to invest in growth- and later-stage AI companies, according to The Information, citing people familiar with the matter. He would be the sole general partner, and the fund is said to prioritize national security. Krishnan previously worked at Microsoft and Twitter and was a general partner at Andreessen Horowitz, where he helped launch its London office; at the White House he worked under AI and crypto czar David Sacks and helped spearhead the AI action plan released in July 2025.
