Hi, I’mDaniel.
I’m a 21-year-old entrepreneur building in ecommerce and AI, focused on brand, growth, systems and ideas that can scale.
I’ve generated over €800,000 in cumulative revenue since I started building businesses.
About me
When I was 12, I started designing websites simply because I loved making things on the internet. I had no idea where it would lead. Before long, I was building sites for my first clients and learning how to turn ideas into things people could actually use.
At 18, I launched Teenwear.eu as a small ecommerce experiment. It gradually grew into an international fashion business and forced me to learn every part of building a company hands-on, from sourcing and brand strategy to marketing, operations, customer experience and growth.
Today, I’m still scaling Teenwear while exploring new ideas at the intersection of ecommerce, technology and AI.
Why I build
I’ve always been obsessed with creating things. It was never about the money.
What interests me most is taking an idea that only exists in my head, turning it into something real and then figuring out how to make it better. That started with websites when I was a kid, continued through dozens of small projects and eventually became Teenwear.
I enjoy solving problems, experimenting, building systems and seeing people actually use something I created.
For me, the interesting question has always been the same:
How far can an idea go if I keep improving it?

The story
Teenwear started in December 2022 with a simple question: could I build an ecommerce brand from scratch? I launched it at 18 and ended up learning every part of the business hands-on, from sourcing and product selection to brand, performance marketing, customer experience, logistics and operations. Revenue reached €93K in its first full year, €205K+ in 2024 and €431K in 2025. More than the numbers, Teenwear became the real-world operating system behind everything I know about building, scaling and improving an ecommerce business.
Sizoo AI
Teenwear’s AI sizing assistant that turns height, weight and real return feedback into smarter size recommendations.

Teenwear’s AI sizing assistant that turns height, weight and real return feedback into smarter size recommendations.
How it works
Sizoo is part of Teenwear and was built to solve one of fashion ecommerce’s most frustrating problems: choosing the wrong size. A customer enters their height and weight, and the AI recommends the size most likely to fit. But it goes beyond a static size chart. Sizoo is connected to Teenwear’s return portal, where it follows customer feedback and return reasons and uses that real-world data to make future recommendations more precise. The result is a smarter sizing experience that helps customers choose with more confidence and is designed to reduce size-related returns.

AI Try-on
An in-house AI experience that lets customers see Teenwear products on themselves before buying.
How it works
AI Try-on turns a product page into something personal. A customer uploads a photo, chooses a Teenwear product and our AI generates a visual of how that piece could look on them. We developed the experience in-house to remove some of the imagination gap from online fashion. Instead of trying to picture an outfit on a model, the customer can picture it on themselves. That makes the decision easier, builds more confidence before checkout and supports sales by helping customers connect with the product before they buy it.
