Obsessing over Matt Long
Straight up, let me put you on to Matt Long, this guy’s a straight-up tech rollercoaster, and honestly, it’s kinda inspiring. So, Matt’s from MIT, which already says he’s got brains, but what really sets him apart is how he’s been jumping into the startup game and crushing it from day one.
He kicked things off with Crocodoc back in the YC Winter batch of 2010. That was his first big move, building this doc viewing tech, getting into YC, and then, boom, Box scooped him up. That’s a huge deal, getting acquired by Box means he was building something real, something people actually wanted. That’s the kind of proof that he’s got the chops.
After Box, he didn’t just sit on his hands. Nah, he kept pushing. He jumped into PlanGrid as a Tech Lead, building and scaling platforms, leading teams, really getting his hands dirty in the trenches. Then he hopped over to Y Combinator itself as a Senior Product Engineer. Think about that, going from startup founder to helping other startups grow. He was all about that “build, scale, repeat” vibe, especially with things like ‘Work at a Startup,’ which is basically YC’s way of helping founders get their shit together.

Talk to herBut here’s the thing, Matt’s not just about jumping into startups. He’s about the grind, the hustle, making things happen. From founding Crocodoc to working at Box, then leading at PlanGrid, and later shaping YC products, the guy’s seen every angle of the startup universe. And now, he’s a founding engineer at Medplum, which sounds like he’s still out here pushing boundaries.
What’s crazy is, all this tells me he’s super motivated not just to build cool tech, but to be the guy who helps others do the same. He’s been there, done that, and now he’s just stacking his experience, probably looking to make an even bigger impact. He’s all about that startup DNA, the hustle, the grit, the constant learning.
Oh, and he’s based in SF, chilling with the South End Rowing Club, that’s some classic Bay Area hustle vibe right there. Dude’s all about staying sharp, staying active, and staying connected.
Bottom line? Matt Long’s one of those guys who’s been in the trenches, built something from nothing, and keeps pushing forward. His process’s a masterclass in what it means to really dedicate yourself to the startup world, not just to make a quick buck but to create something that sticks. No Cap, he’s one of those people you wanna watch because he’s not just riding the wave, he’s making it.
