Thrive Capital

Concentrated multi-stage bets on internet, software and AI companies — fewer positions, deeper founder relationships.

Founded by Josh Kushner in 2009 and run from New York's Puck Building, Thrive deliberately invests heavily in a small number of companies across early and late stages. The firm has raised $22.3 billion across its funds, including a $10 billion-plus Fund X in 2026, and has become one of OpenAI's largest and most consistent backers.
