Ulysse Sabbagh

Hello! Currently building Harsa, Inc. We create, invest in, and grow simple, practical software products and businesses.

Investing in transformative startups: Anthropic, Alinea, Kamea Labs, jitty.

Part of Mozza's product collective in Paris — editing Mozza Bytes (AI insights for French tech) and investing through Mozza Angels to bring product experience to early stage startups.

Writing about software and philosophy on my blog, and curating restaurants and creating recipes at Confit. I also (used to) write a newsletter named Sundry. ~7 links distilled from 80+ sundry sources. Topics are non-linear — we move from flying snakes to chess, from olive trees to Hemingway.
