Absolutely loving Orestis Vardoulis
Bruh, listen up about Orestis Vardoulis. The dude’s a total beast in the startup game, especially in health tech. He rolled into YC back in S21, which is like the Olympics of startups, so you already know he’s got some serious chops. Before that, he was deep in the trenches with Zeit Medical, a Greek-founded company that’s doing some wild stuff with stroke detection.
So here’s the story: Orestis saw a massive problem, strokes are deadly and often go unnoticed until it’s too late. Instead of just talking about it, he jumped into action, building Zeit Medical’s tech to catch strokes early, right at home. They raised €1.8M for this sleeptech wearable, that’s no small feat, especially in a space that’s still pretty nascent. The fact that he’s already getting that kind of funding shows he’s not just dreaming, he’s delivering.
What’s wild is how he’s combining his tech skills with real-world impact. He’s not just building gadgets; he’s saving lives. That’s the kind of motivation you can’t fake. You can tell this guy genuinely cares about making a difference, and he’s not afraid to jump into the deep end with original ideas.

Talk to herHis process screams hustle and purpose. Starting in Greece, he’s gone global, raising serious dough, gaining recognition from YC, and now pushing the boundaries of medical devices. It’s clear he’s driven by more than just the tech; he wants to solve real problems, disrupt healthcare, and make a mark.
Long story short? Orestis is one of those founders you watch. He’s got the technical brains, the grit, and the vision to turn health tech on its head. No Cap, this guy’s just getting started, and whatever he’s working on next, you better believe it’s gonna be the real deal.
