Jimmy Zelinskie

Yo, you gotta hear about Jimmy Zelinskie. Dude’s the real deal in the startup world, especially when it comes to open source and cloud infrastructure. So, he’s a W21 YC alum, which is already a big flex, but what’s crazy is how he got here.

Jimmy’s been deep in the tech game for a minute. Started out as an engineer, no fancy degrees needed, just pure passion. He then jumped into product management, working at some heavy hitters like CoreOS and Red Hat. That’s where he really cut his teeth, leading product teams and getting a solid grip on enterprise software. Dude’s all about making complex stuff simple and democratizing tech, which, honestly, is rare.

What really sets Jimmy apart is his obsession with open source. He’s a big believer in tearing down barriers and bringing the best practices from hyperscalers like AWS, Google, and Microsoft to everyone else. He played a key role in creating SpiceDB, an open-source database that makes authorization decisions smarter and more expandable. That’s advanced stuff. It’s not just about building products, it’s about rewriting how the industry thinks about security and access.

In 2020, he co-founded Authzed, and by 2021, they jumped into YC’s Winter batch. Dude’s been crushing it since day one, turning his deep tech knowledge into a cloud infrastructure company that’s all about application authorization. Basically, he saw a huge gap in how apps handle permissions, and he built a company to fix that. That’s the kind of founder who sees a problem, jumps into it headfirst, and actually creates a solution that matters.

Living in New York, Jimmy’s built a reputation for scaling enterprise software startups and pushing the envelope on open source. His process says a lot about his motivation, he’s not just in it for the fame or cash, but to actually make a difference, make tech more accessible, and keep pushing the boundaries of what’s possible.

Bottom line? Jimmy Zelinskie is one of those founders you look at and think, “This guy is the real deal.” He’s combining deep technical chops with a vision to democratize software, and he’s doing it by building stuff that actually matters. No Cap, he’s here to stay and totally changing the game.
