Guillaume Lachaud

Buckle up, cause I’m bout to tell you about Guillaume Lachaud, the guy’s a straight-up tech beast. He’s one of those founders who’s been around the block and crushed it every time. Started out in France, working at big names like Dailymotion, Backelite, and Sopra Group, so he’s got that solid engineering background, knows his stuff inside out. But what really sets him apart is how he jumped into the startup world and never looked back.

Back in 2019, he co-founded Lantern in San Francisco, a platform that helps product teams track user behavior like a hawk. Think of it as giving the team a superpower to see what users actually do, not just what they say they do. He was the CTO there, the mastermind behind all that magic. Lantern was a serious player for a couple of years, even though it’s no longer around as of 2025. But the impact? Holy shit, that’s still felt. His technical leadership was next level, proving he’s not just about building stuff, he’s about changing how teams understand their users.

Before Lantern, he co-founded Lazy Lantern, another analytics startup, so you can see this guy is all about data and making sense of it. He’s got that entrepreneurial fire, jumping into startups, pushing hard, and building stuff that matters. And his experience at Uber? That’s no joke. He was an ‘everything-engineer,’ which basically means he’s the guy who can handle anything engineering-wise, from backend to frontend, infrastructure, whatever. That kind of versatility? That’s rare. It shows he’s not just a coder but a builder who can wear multiple hats and be productive.

And here’s the kicker, he’s got a foot in both France and the US, working in Paris and SF. That international vibe? It’s like he’s got that global hustle, knows how to guide different markets and cultures, which is gold in today’s startup scene.

So what’s the story here? Guillaume’s process is all about pushing boundaries, building tools that actually make a difference, and not being satisfied with just good enough. He’s driven by a real passion for tech and making a difference. From big corporate roles to jumping into startups, he’s proven that he can lead, innovate, and make shit happen. That’s why he’s so important, he embodies what it takes to be a true builder in this crazy tech world. No Cap.
