About

Yang Xuan · Entrepreneur, investor and author

I care about thinking clearly and doing the work carefully. This site shares judgments about business and investing, hands-on AI experiences, and ideas from reading. Most articles are in Chinese.

Where to start

• Investing notes (Chinese): observations, trade-offs and reflections.
• AI practice (Chinese): setup, maintenance and limitations, not just lists of tools.
• Technology and the future (Chinese): changes and the questions they raise.

Background and books

My work has spanned technology, entrepreneurship and investing. I founded Warp Speed Capital (曲速资本) in 2015; see 36Kr’s report from that year (Chinese). The author biography for my 2017 book (Chinese) describes my earlier role as managing director of the venture fund 浙报集团梦工场创投基金.

My two published books, 《创业时，不可不知的细节》 and 《保卫钱包：家庭财富新方程》, cover early-stage business questions and household finances. Read about the books and their bibliographic sources →

How to read these notes

Historical articles keep their original publication dates. Excerpts and edited collections explain their scope. An earlier experience is not a statement about a tool’s current behavior, and earlier judgments can be revisited. Background and books provide context, not a guarantee of results.

Questions, corrections and conversations about the articles, AI practice, business or reading are welcome.
