Oleg Zaremba

Here’s someone who’s absolutely crushing it. Oleg Zaremba – this guy’s a straight-up tech beast from Ukraine who’s been crushing it since day one. No bullshit. He’s like that kid who jumped into coding at 16, and by 24, he’s already the youngest Senior Software Engineer at Booking.com. That’s no small feat, especially considering he’s got some serious academic creds in applied math and nanotech from top universities. Basically, the dude’s brains are on another level.

But what really makes him stand out is his hustle. He’s been through the startup grind twice – first with AXDRAFT, a legal document automation company he co-founded that went through Y Combinator in 2019. These guys made legal stuff crazy simple, and boom – they got acquired by Onit in 2020. That’s a legit success story. After that, Oleg stayed on as Director of Software Engineering at Onit, leading AI and product development. The guy’s all about building stuff fast, making it work, and pushing tech boundaries.

Then, in 2023, he jumped into YC again with AiSDR, an AI-powered sales automation startup. He’s the co-founder and CTO now, pushing the envelope in AI. Seeing him do it twice with YC? That’s no accident – it shows he’s got that entrepreneurial fire, the real deal motivation to build something meaningful, not just chase shiny tech.

Plus, he’s super proud of his Ukrainian roots, choosing to stay in Lviv and keep his culture front and center – that’s a big part of his story. He’s all about tech, innovation, and making a difference, no matter where he’s from. And he’s recognized as a Forbes 30 Under 30 – that’s the proof he’s legit.

Bottom line: Oleg is this rare combo of technical genius, startup hustle, and cultural pride. He’s the kind of guy who jumps into the fire, learns fast, and comes out stronger. He’s not just building software – he’s shaping the future of AI and automation, all while staying true to his roots. No cap, he’s one to watch.
