By background, I'm an engineer who became obsessed with building things. I love understanding how systems work (tech, business, politics…) and thinking from first principles. I tend to design pretty ambitious visions, usually where the best opportunities are hiding.
That approach has served me across multiple ventures. I co-founded Luko, which became France's #1 online home insurer before joining Allianz Direct. Before Luko, I cut my teeth on two ventures: a vertically integrated food delivery startup called Goodfood (think early Frichti) that we expanded to Berlin and London with Rocket Internet, and OpenJet, a SaaS marketplace for private jets across the US and EU. Each taught me something different about timing, product-market fit, and the art of solving real problems elegantly.As an angel investor and Accel Scout, I've backed 20+ startups including Tomorro, Stoïk, Finary, and Orus.I grew up in Grenoble where ski trips were basically mandatory, and have since lived in Paris, Lyon, Berlin, London, Brazil, and NYC. I speak Portuguese and Spanish, love kitesurfing, skiing, and recently discovered woodworking - a surprisingly good way to quiet my brain and my passion for design.
AI is shifting from a tool to an omnipresent layer, reshaping how value is created and decisions are made across the entire economy. I'm exploring several core themes, but I'm starting with one that's already happening under our noses.
"AI as the Buyer" is the idea that an increasing share of purchasing decisions will be made directly by AI systems, or heavily influenced by AI analysis. This isn't just about e-commerce, it's reshaping B2B and B2C industries in ways most people haven't grasped yet. As AI-driven decision-making accelerates, businesses will need entirely new infrastructure to be discovered, evaluated, and integrated into AI-native workflows.
Here's the thing: today's business stacks are optimized for human buyers. But purchasing decisions are already being intermediated by AI analysis. Every company will need to learn how to sell through AI.
The opportunity is much broader, I'm also exploring Physical AI, particularly in defense and robotics.
I'm looking for founders looking either build US-first companies, designed for global scale, leveraging Hexa’s San Francisco presence, including its newly launched founder house and growing founder community. Or european sovereign companies, built to thrive in regulated environments while supporting key European strategic priorities.
