Rangel Milushev

Yo, you gotta hear about Rangel Milushev. This guy is the real deal in the startup world, no cap. So, he’s a YC W23 alum – jumped into the scene recently but already crushed it. His story? It’s all about tech, AI, and making shit happen that actually matters.

Started out at Harvard, right? B.A. in CS, and he was all over the place – teaching CS50, doing research, the typical nerdy grind but with a twist. Dude’s always been into building stuff that pushes boundaries. After Harvard, he jumped straight into the startup game, co-founding a few companies like Cartesian Network and Crimson Analytics. Basically, he’s been deep in data and analytics from day one. That shows he’s got the brain for complex shit but also the hustle to turn ideas into products.

Then, he worked at AppTweak as a Full Stack Engineer and Performance Analyst. That’s where he got hands-on experience with the nuts and bolts of tech and marketing. But here’s where it gets interesting – he didn’t stop there. He was an Entrepreneur in Residence at Entrepreneur First, which is basically a bootcamp for founders to get their ideas off the ground. That’s where he really started jumping into the deep end with new ventures.

Fast forward, he’s now the CEO and co-founder of BabylonAI. This is his current big thing – a company all about giving AI teams the tools to log, analyze, and get practical insights from their computer vision and ML projects. Think of it like the ultimate backstage pass for AI devs. It’s super niche but totally key for anyone working in AI at scale. That’s some real B2B SaaS shit that’s gonna make waves.

But wait, his biggest hit? rex.fit. This is the one that’s probably gonna blow up – automating nutrition with AI-powered devices. They launched “The Drop” on Kickstarter in 2025, and holy shit, that’s legit. It’s not just some fitness gadget; it’s about making health tracking dead simple, accessible, and personal. Dude’s got a vision for tech that’s not just cool but actually changes lives, especially when it comes to health.

What does this all say about him? Rangel’s got this relentless drive to build stuff that’s original but also practical. He’s not in it just for the hype – he’s all about solving real problems, whether that’s making AI teams more fast or helping people eat better. His process shows he’s super motivated by making a tangible impact. He’s a builder, a thinker, and a doer – the kinda guy who sees a problem, jumps into the trenches, and comes out with something that actually works.

Bottom line? Rangel Milushev is one of those rare founders who combines hardcore tech skills with a vision to change the game. He’s got a track record of jumping into tough problems, and he’s just getting started. Keep an eye on him – he’s gonna be one of those names you hear a lot more in the next few years.
