Marc Laurent

Founder

I've cofounded seed VC firm Kerala Ventures when I was 25yo. We invested €11M in 16 seed startups including Doctolib (now $4b valuation), Malt ($500M), Playplay ($200M) and 13 other. x17 Cash-on-Cash multiple, x3.5 realized. I led 100+ recruitments for Kerala's portfolio. I love surfing but I deeply suck at it. #NeverGiveUp

Romain Champourlier

Founder

Mix of entrepreneur and software engineer, I build software and teams to build them. I'm currently building Carbonfact, a climate-tech SaaS to decarbonize fashion. I previously worked in a French HR-tech startup, JobTeaser during 7 years, where we helped millions of students find a job and career that better matched their skills and expectations.

Martin Daniel

Founder

I started my career at Google and worked at Airbnb as a Data Science Lead. I founded covidliste.com which became the largest waiting list for a Covid-19 vaccine in France (~1m people notified) or dataforgood.fr (~2k data scientists volunteering on non profit projects). Carbonfact decarbonizes the apparel and footwear sector.
