Let me introduce Oskar Koristka
Shoutout to Oskar Koristka, this dude is the real deal. He’s one of those guys who jumped into the startup scene and just crushed it from the get-go. So, he’s a W19 batch guy at Y Combinator, which already says a lot, YC isn’t messing around, and he got in with Supernova, a super slick design system platform. Think of it like the backbone for other apps and products to build on, that’s some serious tech magic.
But here’s the thing, Oskar didn’t just get lucky and coast. He’s been all over the place, wearing different hats. Before Supernova, he was the COO, so, the guy was running things, making sure everything clicked. And he’s also been the CEO at Pupin media, which shows he’s got that leadership DNA, knows how to steer the ship. He’s also done production management at OCCAM PR, which is all about coordinating chaos and making shit happen, plus he’s nailed freelance gigs, so he’s got that hustle vibe going.
What’s wild is his background. He’s worked with big organizations like Česká spořitelna, a major bank in Czechia, and Sprint, plus some volunteer stuff with the Kridleni endowment fund, giving back, raising funds, the whole shebang. That shows he’s not just in it for the tech, but cares about having an effect and building community.

Talk to herAnd get this, he’s got a business degree from Business School Ostrava, so he’s got that solid knowledge base. But what really stands out is his drive. This guy saw opportunities, jumped in, and kept pushing. Starting Supernova at YC? That’s not something you do if you’re just dabbling. It’s clear he’s all about building tools that matter, making a dent, and pushing the boundaries of what’s possible.
So, why is he important? Because Oskar embodies that startup hustle, the kind that’s all about turning ideas into reality, leading teams, and doing shit that actually changes the game. He’s not just riding the wave; he’s shaping it. That’s why you gotta keep an eye on him, he’s one of those founders who’s gonna keep crushing it and making waves.
