Petar Matejic

So check this out about Petar Matejic – the guy’s a straight-up tech wizard with a crazy story. So, he’s the CTO and founder of Vista Power, a company that’s crushing it in the energy storage game, especially for big biz stuff like data centers, hospitals, and factories. Their main thing, the Voltaris system, is all about behind-the-meter tech that helps companies cut energy costs by up to 30%, keep the lights on during blackouts, and just make energy way more reliable.

What’s wild is that Petar didn’t just wake up one day and start this. His background is deep in advanced engineering – he’s worked at NASA, SpaceX, Firefly Aerospace, even The Boring Company. Dude’s no stranger to pushing tech to the limit. That space-tech vibe is part of what fuels his passion for innovation. And get this: he didn’t stop at just energy storage for the grid. He co-founded Vista Space, building Tesla-inspired structural batteries for satellites. Basically, making satellites smarter and more strong without cramming in more size. That’s some advanced thinking.

His process screams one thing – he’s all about pushing boundaries. From rockets in space to batteries on Earth, he’s someone who sees problems and just jumps into solving them with crazy tech. He’s been part of YC’s W24 batch, which is a big deal – that’s where the real movers and shakers hang out. It shows his startups aren’t just some small side projects; they’re the real deal, high-growth, venture-backed stuff.

What I love about Petar is that his whole story is about combining space-grade tech with Earth problems. The guy’s driven by a real motivation to make energy cleaner, cheaper, more reliable – to basically solve some of the biggest issues out there. He’s not in it for just the bucks – he’s got that space-science ambition, that “let’s change the world” vibe.

Bottom line: Petar Matejic is a tech pioneer who’s bridging space tech and energy storage – pushing the envelope, making big moves, and showing us what’s possible when you don’t settle for bullshit. This guy’s the real deal, and if you ask me, he’s just getting started.
