Summary
👤
Senior🎓
Top SchoolEtienne Depaulis is a seasoned software builder and seed investor with 13 years of experience crafting scalable web products using Ruby, Elixir and Node. He co-founded multiple startups—including Lifen, where he led architecture and engineering efforts for healthcare document exchange—and runs Endheo, a SaaS and consulting firm he founded in 2013. Comfortable both shipping code and scaling teams, he has repeatedly turned technical bets into exits (e.g., Planning de Garde, SIAJE, Dendreo) and now backs early-stage ventures across climate, health and productivity. Based in Chassieu, France, he blends hands-on engineering discipline (TDD, high test coverage, K8s) with product instincts honed by board-level experience. A detail that often surprises colleagues: he introduced Ruby into legacy Java environments early on and built a mission-critical Rails app with 97%+ test coverage while mentoring junior developers.
