Tanguy Goretti
I've been writing code since I was 13 and never really stopped. I co-founded Cowboy, where we built a connected e-bike from the ground up and put more than 80,000 riders on the road across Europe - hardware, firmware, apps, and everything that breaks when you scale all three at once.
I joined Hexa as CTO to work on the earliest and messiest part of company building. I support CTO founders, shape how we look at AI as an investment lens, and run CTO Voices (an event series hosted at Hexa) and Off the Radar, two formats built to get Europe's best technical people in the same room.
What I actually help with is narrow and practical: deciding what's worth building and what isn't, making the architecture and first-hires calls you'll live with for the next three years, and giving an honest read on whether AI changes your product or just your demo.
Outside of work, I train for HYROX. It's the same lesson as building a company: the result is decided months before the day itself.
Founders who build. people who ship, feel the product in their hands, and can tell the difference between something that works and something that demos well.
Speed with judgment. I care less about how fast you move than about how fast you learn you were wrong. The founders who stand out ship on Monday, get told it's wrong on Wednesday, and have changed direction by Friday, without losing conviction on where they're going.
And a real reason to be the one doing this. Technical founders have more good options than anyone. If you're building a company, it should be because the problem won't leave you alone, not because it looked like the logical next step.
