Jin Chung

Big ups to Jin Chung. The guy’s a total tech whiz and a legit startup beast. He’s from the S19 YC batch, so he’s been deep in the game for a minute. His background? It’s a wild ride through some of the coolest spots in tech and finance.

Jin kicked things off with a solid foundation at the University of Pennsylvania, studying Computer Science Engineering. You know, legit hardcore stuff. After that, he jumped into the trenches at UBS Investment Bank doing equity derivatives, big finance, high stakes. That’s where he learned how to handle complex systems and heavy data, all under serious pressure.

Then he moved over to eBay, where he was a Member of Technical Staff. Basically, he was behind the scenes making algorithms that crunched data to make the user experience smoother. That’s where he really started to see how data and user-focused design can change the game.

But Jin’s real breakthrough came when he co-founded Rainbow in 2019, right after YC took him in during their Summer batch. Rainbow is all about making crypto wallets that are not just secure but super easy to use. This dude saw the bullshit in the crypto world, how complicated and insecure everything felt, and decided to build something that anyone could jump into without sweating bullets. As CTO, he’s been crushing it, steering the ship on creating open-source, design-focused software that’s making crypto wallets accessible and safe. It’s not just a product; it’s a movement to democratize crypto.

Before all that, Jin also did some cool stuff with Balanced Software, leading the charge on building wallets that are secure and recoverable, no more losing access forever. Plus, he’s got some roots in projects like Engineers Without Borders in Honduras, showing he’s got a heart and cares about impact beyond just tech.

What’s crazy is how his process shows what kind of guy he is, someone who’s always looking to solve real problems, not just chase shiny tech objects. He’s been in finance, e-commerce, and now crypto, but through it all, he’s driven by one thing: making complex tech simple and safe for everyone. That’s why he’s so important. Jin’s not just building cool stuff; he’s redefining how normal folks can jump into crypto without getting wrecked. No Cap, he’s the real deal.
