Jonathan Hsu is a PhD string theorist turned venture capitalist who led Facebook's data science organization from a handful of people to over 150 and created widely-used growth analytics frameworks before moving into investing. At Tribe Capital, he built the Magic 8-Ball system that analyzes raw product data to measure product-market fit across different business models, and routinely provides founders with detailed analytical audits of their growth and retention metrics even when passing on investments.

• A heavy emphasis on using data science to quantify product-market fit rather than relying on gut feel or narrative alone. He frequently references specific frameworks like Growth Accounting to understand the patterns of a healthy business, such as when he shared his detailed guest post on the Amplitude blog regarding the components of measuring product traction.
• Prioritizes unit economics as a fundamental lens for evaluating startups. He views the relationship between data science and product-market fit as parallel to the relationship between accounting and financial health, a philosophy he elaborated on when releasing Tribe Capital's initial writings on their diligence process.
• Interest in the strategic importance of distribution channels and market sizing mechanics. He specifically highlighted a discussion involving the CEO of Carta that challenged conventional wisdom, noting that owning lines of distribution is key and that smaller markets can actually be highly attractive entry points.
• A passion for live music performance which serves as a unique personal connection point. He regularly tweets about playing gigs at San Francisco venues like Atlas Cafe and Mr. Tipple's Recording Studio, inviting his network to come watch him perform with his bandmates.
