Check out Oguzhan Atay

Yo, have you heard of Oguzhan Atay? The dude’s a straight-up genius and a total boss in biotech. He’s the guy behind BillionToOne, a company that’s totally flipping the script on molecular diagnostics. Basically, they’re making these tests way more accurate, faster, and way more accessible, like, changing the whole game.

So, OG’s from Turkey, but he’s been crushing it in the US and UK too. Went to Princeton, graduated summa cum laude and Phi Beta Kappa, which is no joke. He didn’t just stop there, he went all the way to Stanford, got a PhD in Systems Biology, and his research was featured on the cover of Cell Systems and published in some of the top journals out there. That’s some serious nerd cred, but also shows he’s got the real skills and vision.

Back in 2017, he jumped into Y Combinator with BillionToOne, which is basically the startup Olympics, so that tells you he’s no stranger to the grind and big ideas. Since then, he’s led BillionToOne from the front, raising over $200 million from big-name investors. That’s a massive feat, especially for a biotech startup. His secret? Not just smarts, but real passion, he’s driven by a desire to make early detection better, more reliable, and accessible for everyone.

Talk to her

What I find super inspiring about him is how his process screams dedication. From Turkey to Princeton, then Stanford, and now leading a company that’s pushing the boundaries of science. It’s like he’s been chasing this vision his whole life, using his deep research background and tech skills to actually build something that can save lives. That’s what startup life is all about, right? Taking crazy ideas, working your ass off, and actually making a dent in the universe.

Long story short, Oguzhan is one of those rare tech founders who combines top-tier academic chops with real-world hustle. He’s not just about the science, he’s about making it count. That’s what makes him stand out. No Cap, he’s the real deal.
