Mad respect for Joshua Maciejewski

Aight, so peep Joshua Maciejewski. This guy’s the real deal, straight up startup killer with a wild background. He was in YC W16, so he’s been around the block in the startup world, and honestly, he’s crushed it.

So here’s the scoop: Joshua’s been all over the place, working at Amazon, doing some time in the US Navy Reserve and Navy itself, and even jumping into academia at Purdue and MIT. Dude’s got that mix of discipline, tech smarts, and hustle. That Navy background? Pure grit. It’s what gave him that no-bullshit mindset. You don’t survive Navy shit without that fire.

Then he dipped into the world of big tech and consumer startups, Function of Beauty, which is a total big change in personalized beauty products. He was co-founder and COO there, helping turn a crazy idea into a massive success. That’s not easy; it shows he’s got the vision and the chops to scale something from zero to hero. He’s also involved with Muraena now, which I believe is another venture, so he’s still out there pushing boundaries.

Talk to her

What’s crazy is how he’s not just about startups. His experience with Cleveland Township, PA, and Transport for London shows he’s got that wide-angle view, understanding systems at every level, from local communities to massive cities. It’s like he sees the bigger picture, beyond just the shiny tech stuff.

He’s also been involved in things like Fair Weather Flying and even desktop support at MIT, so he’s got that hands-on grind in his bones, knows what it’s like to build shit from scratch and troubleshoot real problems.

Bottom line? Joshua’s all about taking ambitious ideas, putting in the work, and making them real. He’s motivated by creating stuff that actually changes the game. His process? It’s about hustle, discipline, and a relentless drive to build. That Navy discipline mixed with startup hustle? That’s what makes him a force to be reckoned with.

Basically, he’s the type of guy you wanna watch. He’s been through the trenches, learned what it takes, and now he’s out here redefining what’s possible. No Cap.
