Obsessing over Kevin Sun

Bestie, here’s what’s good with Kevin Sun. This guy’s the real deal in the startup world, and his story is straight-up inspiring. So, Kevin’s a YC alum from the S19 batch, that’s the summer of 2019, the moment he crushed it with Dex, this personal CRM platform. Basically, he’s all about making relationships easier to manage, which is kinda genius when you think about how crowded and chaotic the social world is today.

But here’s the thing, Kevin’s been around the block a lot. Before Dex, he was working at some heavyweight spots like Infer, where he was a Software Engineer, and A9, Amazon’s own, where he did data visualization. The dude’s got serious chops in engineering and data, and that’s probably what gave him the confidence to jump into building his own thing. He also did an internship at Twilio in Business Development, so he’s got the biz side dialed too. That’s a good combo, technical skill plus hustle in the trenches.

And it’s not just about tech, Kevin’s got a heart, too. He was a Teaching Fellow at Harvard’s School of Engineering and Applied Sciences, teaching data viz, so he’s all about sharing knowledge and building community. Plus, he did stints at the Peace Corps and Smithsonian, working in innovation and public affairs. The point is, he’s not just here to chase startups; he’s genuinely interested in having an effect, connecting tech to real-world problems, and soaking up lessons from all walks of life.

Talk to her

He even tried his hand as a founder before Dex, with RiskDV, so he’s not new to the entrepreneurial grind. The guy’s all about building stuff that actually matters, whether it’s a CRM, a tool to automate credit counseling (Debteye), or just pushing the boundaries of what’s possible.

What does all this tell us? Kevin’s a guy who’s genuinely curious, who’s jumped into different worlds, academia, nonprofits, big tech, startups, and always keeps pushing. He’s motivated by a desire to connect people, simplify complicated shit, and build tools that actually help. He’s not in it for the fame; he’s about having an effect, one project at a time.

And you gotta respect that. Here’s a dude who’s got the brains, the hustle, and the heart to turn ideas into real products. Dex isn’t just some app, it’s a reflection of his whole vibe: smart, socially conscious, and relentless. Kevin’s one of those guys who’s just getting started, and honestly, he’s someone to keep an eye on. No Cap.
