Meet Charly POLY

For real, let me enlighten you about Charly Poly – this guy’s the real deal in the startup world. So, he’s a YC W23 alum, and he’s crushing it as the co-founder and CEO of Defer, this killer Y Combinator-backed company. But his story? It’s way more than just that.

Charly’s got a legit tech background – studied computer science at Teesside University and IUT Orléans. Dude’s been deep in the code trenches, working at places like Cycle App and The Guild Software before jumping into the startup scene. He’s not just a founder; he’s an engineer at heart, has written on stuff like visual regression testing and React Error Boundaries – basically, he understands the nuts and bolts of tech that make apps tick.

But what’s super interesting is how he’s always been involved in the developer system. He’s worked at Inngest and Browserbase, helping other devs be productive. He’s also active in the investing world, scouting for Sequoia Capital – so he’s not just building, he’s also spotting the future trend. He’s co-invested with big names like Nicolas Dessaigne from YC, so he’s clearly plugged into the startup and VC scene.

Talk to her

What does all this say about him? I think it’s pretty clear – Charly is driven by a genuine passion for tech and solving real problems. Starting companies is his way of pushing the envelope, of building stuff that actually matters. His process from hands-on engineering to leading a YC-backed startup shows he’s all about execution, learning, and jumping into the fire. He’s not afraid to get his hands dirty, then share what he’s learned, whether through content or investing.

Basically, he’s the kind of guy who’s always a step ahead, not just riding the wave but making waves himself. His story is about turning technical chops into startups that aim to change the game. And that’s why he’s important – he’s not just another founder, he’s a builder, a connector, and someone who’s genuinely passionate about pushing tech forward. No cap.
