Early-stage AI partnerships at Microsoft
Angel investor in San Francisco

I back technical founders building developer tools, AI infrastructure, and the systems behind production software. The best calls usually start before there is a round to talk about.

At Microsoft, I work with seed and Series A founders building on Azure and the broader Microsoft AI stack. Before that, first hire at Abel, a Y Combinator company backed by Garry Tan and AI Grant. Computer science at Cornell.

Angel investing since 2019, often alongside Y Combinator, AI Grant, and other San Francisco funds and operators.
