Julien Brissonneau

Yo, so Julien Brissonneau, this guy is the real deal in the startup world, no cap. He jumped into the scene back in W17 with Y Combinator, which is like the holy grail for early-stage startups. That already tells you he’s got some serious hustle and vision, right? Not many get into YC, and even fewer crush it enough to keep pushing forward.

His background? Man, he’s been around some heavy hitters, Ledger Investing, Pioneer Fund, Thales Group, Crédit Agricole, and Laser Based Diagnostics. That’s a wild mix, from big finance and corporate giants to deep tech and diagnostics. It’s clear he’s got a knack for crossing industries and understanding both the tech and money side of things.

But here’s where it gets interesting. He’s now the founder and CSO at Ledger Investing, which is basically creating a marketplace for insurance securitization. Think about it, insurance is a massive, complex beast, and Ledger is trying to turn that into a more fast, maybe even more transparent process using tech. That’s some advanced stuff. He’s not just doing startups for the hell of it; he’s tackling real-world big problems with original solutions. This guy’s motivated by making things better, smarter, faster, bullshit can’t stand in his way.

Before all this, he was deep in finance and tech, working with Pioneer Fund and Thales. That tells me he’s got a serious understanding of how capital flows and how to use tech for massive impact. Plus, his experience at Laser Based Diagnostics shows he’s into modern tech, not just finance. Dude’s got the full spectrum, finance, tech, startups, big companies, he’s been everywhere, learned a ton, and now he’s using all that juice to build something that could seriously change how insurance and finance work.

So, what does this say about him? Julien’s all about pushing boundaries. He’s not afraid to jump into complex, messy industries and shake things up. His process shows he’s motivated by solving big problems, not just chasing quick wins. He’s got the perfect mix of tech smarts, finance savvy, and startup grit. That’s why he’s important, because he’s not just doing cool shit, he’s building the future of how industries operate, making them more transparent and fast.

Bottom line? Julien Brissonneau is one of those guys who’s been around the block, seen what works and what doesn’t, and now he’s out here changing the game. Keep an eye on him, he’s just getting started.
