Have you met Alexei Karpenko

Yo, you gotta hear about Alexei Karpenko. This guy’s a straight-up tech wizard, and his process is legit inspiring. So, he came out of YC W12, yeah, the same batch as some big players, and he’s been around the block at some heavy-hitters like Facebook, Apple, and even electrobee. Dude’s got that deep tech pedigree, no doubt.

But what really hits home is his move into startups. He co-founded Midnox, which later rebranded as Luma. This wasn’t just any video app, these guys were working on HD video recording with real-time stabilization, filters, zoom, all that jazz. Imagine being able to change filters and stabilize your videos after shooting, that’s advanced. Plus, they threw in social features so you could follow friends, like, comment, basically making mobile video social before that was really a thing. That’s some serious innovation, and it shows he’s all about pushing what’s possible with mobile tech.

Eventually, Midnox/Luma got acquired, and their tech pushed mobile video forward big time. That’s a major win, it’s not just about building something cool, it’s about creating tech that moves the industry. And it screams that Alexei is not just some coder, he’s a builder who wants to shake up how we share and consume video.

What does this say about him? Dude’s got a relentless drive for innovation. He’s jumped into the startup scene, played around with big tech, then took all that knowledge and built something that mattered. His experience at Facebook and Apple? That’s not just a resume filler. That’s a sign he’s been in the trenches with the best, learning what it takes to move fast and crush it. And then he took that hustle and applied it to his own startup, that’s real passion.

Alexei’s story is about more than just tech. It’s about seeing a problem, having the guts to build something new, and then making it stick. He’s the kind of founder who’s not afraid to get his hands dirty or challenge the status quo. His process shows that starting something big isn’t about luck, it’s about smarts, grit, and knowing when to jump.
