About
I dropped out of École Normale Supérieure at 21 to build Doctrine, which became Europe’s largest legal information platform with 25,000 customers. Along the way we sued France before the European Court of Human Rights to force the open data of court decisions. Doctrine was acquired by Summit Partners in 2023.
I moved to San Francisco and started Fintool, born out of my admiration for Buffett and Munger. I wanted to build an AI that could analyze businesses exactly like Warren does: reading filings, building conviction one annual report at a time. Fintool was backed by Y Combinator, Anthropic, and Menlo Ventures, and acquired by Microsoft in March 2026.
Now at Microsoft, I’m working on bringing the most advanced agentic AI experiences to the hundreds of millions of people who use Word, Excel, and PowerPoint every day.
Outside of work, I train Brazilian jiu jitsu and bike around San Francisco.
