Can't sleep on Paul Sanglé-Ferrière
You absolutely need to hear the story of Paul Sanglé-Ferrière. This guy’s a total beast in the startup world. He’s one of those founders who just jumps in, crushes it, and keeps coming back for more. So, Paul’s the co-founder of cubic, this badass AI-powered code review platform that just got into Y Combinator’s X25 batch – which is no small feat, by the way. They’re based in London, and he started this thing in 2025 with his partner Allis Yao. The goal? Replace Github with some next-gen AI that makes team collaboration and code review way smoother and faster. No bullshit, that’s a big change.
But here’s the kicker – Paul isn’t new to this game. He’s a repeat founder who’s been around the block. Before cubic, he was involved with other companies like mrge, Workflow, and even Yelp. That’s a pretty diverse lineup – shows he knows how to build, scale, and hustle. Dude’s got that entrepreneurial DNA, for sure. He’s not just throwing ideas out there; he’s actually built stuff that’s been tested in the real world.
And get this – cubic has some serious investors backing it. Names like Vercel Ventures, PeakXV, Jared Palmer, Theo Browne, and Zeno Rocha. These guys don’t throw money around lightly. They see something in Paul, in cubic. It’s that mix of technical genius and startup hustle that makes him stand out. He’s not just some guy with a cool idea; he’s the real deal who’s jumped into the deep end and is making waves.
