Paul Hsiao is known for his structured "5 fundamentals" framework for evaluating marketplaces (liquidity dynamics, repeat behavior, unit economics, category timing, and founder-market fit) and his belief that serious marketplace founders need to think about raising $100M+ to dominate categories. He spent a decade at NEA helping companies scale from garage startups to IPO, giving him pattern recognition shaped by both early-stage formation and late-stage scaling experience.
