Alejandro Lozdziejski

Yo, you gotta hear about Alejandro Lozdziejski. This guy’s a total beast in the startup world. He’s been crushing it for over 15 years, and his story is one of pure hustle mixed with mad tech talent.

So, Alejandro’s a computer nerd turned entrepreneur, but not just any nerd. He’s the real deal. Started out with a solid software engineering degree from Universidad ORT Uruguay, then jumped into the tech scene, working at places like Tata Consultancy and U Intelligence. But what really set him apart was his passion for making stuff that actually changes the game.

Back in the day, he founded Selva 3D at Sur3D, which was all about 3D printing, super futuristic, right? That’s where he started messing with personalization and custom products, basically the roots of what he’s doing now. Then he went on to become a software engineer at Interzoic Media, gaining more experience, but always staying hungry for that entrepreneurial fire.

Fast forward, he co-founded Customily, which is straight-up the future of ecommerce design tools. It’s a platform that hooks into Shopify, Etsy, WooCommerce, basically any big online store, and lets them sell personalized stuff like apparel, jewelry, stationery, you name it. This guy saw a huge gap in the market and built a tool that makes it easy for stores to sell custom products without bullshit. And get this, he got into Y Combinator’s S21 batch, that’s the big leagues, man. Only the best startups get in there.

What’s crazy is, Alejandro isn’t just a coder. He’s recognized as an MIT Innovator Under 35, that’s a legit honor that only the most new minds get. It shows how much he’s pushing boundaries in personalization and 3D printing. He’s all about making tech that’s not just cool but actually useful.

He’s also studied entrepreneurship at UC Berkeley’s Haas School of Business, so he’s got the brains on both the tech and business side. That combo? That’s what makes him a total force.

Honestly, what I get from his story is that Alejandro is the kind of guy who sees the future and just jumps into it. He’s been in the trenches, building stuff, failing, learning, and then crushing it. His process screams that starting something real means being relentless, no bullshit, no excuses. Just pure passion for creating tools that change how we do business and personalize everything around us. That’s why he’s so important, he’s not just riding the wave; he’s shaping it.
