A personal collection of work & ideas

Pengyu Hao 郝鹏宇 · Peter

Curiosity,
put to work.

I study mathematics, build AI tools, and research businesses. I like taking a question far enough to make something useful.

02

AI & the economy

AI investment returns, consumer monetisation, and white-collar automation.

03

03 / A little context

Hi, I’m Pengyu.
You can call me Peter.

I’m studying Mathematics with Data Science at the London School of Economics and Political Science. My interests sit between mathematics, software, and investment research.

I enjoy working through the details: how a company earns its returns, how an agent handles a long task, or why a particular move works on the Go board.
