👋 Welcome to Hance Zhang’s Blog

Hance Zhang writes about AI, product building, business models, investing, and human relationships. Across these topics, he is ultimately interested in one thing: structure.

His work explores how incentives shape behavior, how time amplifies what is already there, and how systems quietly train people, organizations, and markets over the long run. Rather than focusing on slogans or stated values, he is interested in the deeper mechanisms that produce durable outcomes.
