I live in San Francisco and mainly work on Paso, a founder's partner for teams building toward product/market fit. Before that I cofounded Tap Go, a cold brew coffee brand in Shanghai, and A'GAIN, which made home goods from spent coffee grounds. I grew up in Tianjin, trained as an ecologist and previously studied at Penn.

What is the right product at the right time? It is the question I work on with founders at Paso. How does a founder tell a wrong product from a right one that is early?

In my earlier companies, my idea of a product was missing the market. How often does a founder need to meet customers before the product starts to change?

What makes an object both functional and tasteful? When does taste help a young company, and when does it get in the way?

Cold brew reaches a customer through a supply chain, a store and a delivery. Tap Go taught me how much of a business sits in that sequence. How does a founder learn a complex workflow without first working inside it?

Where do founders and investors disagree about the same company? What does each see that the other cannot?

What lets a group reach a decision its members could not reach alone? I gave lectures for 200 to 300 people at Studio Alpha. I am starting Open Discussion, a monthly live conversation online where founders bring a decision they are facing. It runs in Chinese first. The first date is not set.

The longer aim. How can people and nature live better together? At Penn I worked on a regional plan for Dhaka's leather industry and its river. What would it take for an industry and the river beside it to both do well?
