Zlatko Jončev

Yo, have you heard about Zlatko Jončev? The dude’s a total beast in the startup scene right now. He’s part of YC’s S25 batch, which is a big deal, and he’s out here building some advanced shit with his company, b-12.

So here’s the scoop: Zlatko started b-12 to totally change how chem and pharma R&D works. Like, he’s aiming to create what he calls “chemical super intelligence.” Basically, autonomous labs that can plan and do complex syntheses without much human help-like AI-powered robots in the lab that think and act on their own. That’s wild, right? This isn’t just some boring automation, it’s modern stuff at the intersection of AI, robotics, and science.

He’s been crushing it too-b-12 grew profitably to $2M after he split from his co-founder post-YC. That’s no small feat. It shows he’s not just tech-savvy but also got the hustle and grit to take something from zero to millions, even after a major partnership shakeup. It’s like he’s always been about pushing boundaries, not waiting around for someone else to do it for him.

What really jumps out about Zlatko? His motivation. The guy sees the future of science not just as labs and chemicals but as a place where AI and robotics can totally speed up discoveries and save lives. He’s working at the absolute frontier-building physical AI that can think, plan, and execute in real labs. That’s some sci-fi shit turned real.

And his story? It’s all about jumping into the deep end. Started with a big vision, built a company that’s now part of YC’s elite, then split with his co-founder but kept his eye on the prize. Instead of crying over the split, he doubled down, grew profitably, and is now pushing forward with even more fire. That’s what I call real founder energy-resilient, ambitious, and totally unafraid to take risks.

Bottom line? Zlatko’s not just another founder. He’s the real deal. He’s out here blending AI, robotics, and science to make the next wave of innovation happen. The dude’s on some advanced shit, and honestly, I wouldn’t be surprised if in a few years everyone’s talking about how he changed pharma R&D forever. No cap.
