Xuguang (Hector) Ren

Venture builder & investor.

I'm Hector — formally Xuguang Ren. I build companies from zero and invest in founders who are early, ambitious and technical.

This site is where I think in public: essays, research notes, startup ideas I'd like to see exist, and the ventures I'm working on or backing.
