I'm the founder & CEO @ Upstream. I was one of the early product people @ Asana, driving growth and adoption up to $100M ARR. I went on to lead the entire product team @ Algolia (YC W14) as their Head of Product through series B and C, assembling a team of 20+ talented product builders, while growing ARR 2.5x to $100M+. Also worked @ AgilOne (acquired) and graduated from @ Stanford and @ Ecole des Ponts
I am the co-founder & CTO @ Upstream. My love for software started when I was only a teenager: I developed @ Dino Gaia, one of the most popular online French consumer games in the 2000s, registering a million visits every month. I've since built extensive technical hands-on and leadership experience across multiple sectors, including ride-hailing, fintech, and legaltech. I was most recently the VP of Engineering @ Doctrine before it got acquired.

No investor is drawn from a Form D — the form states how many invested and never who. The one investor on this graph is named because a batch has exactly one.

Watchlist UpstreamYou get an alert in MentionFox the next time this company shows up.
If you're behind Upstream: acceptance into a YC batch is one of the few weeks a young company gets looked up by people who matter — investors, other founders, press. FoxPlug turns the commits, deploys, and releases you're already making into that story automatically, so anyone who looks finds something current. GetFoxChat puts a guide on your own site so the people YC's own page just sent you don't read one line and leave.
Sourced from the company's Y Combinator directory entry, and from the company's own site, read directly on 2026-09-27 (upstream.do).
