Growth Studios
About us

We build the software we needed ourselves.

Ten years of operations in a pro sports league, multiple sports brands and e-commerce. That's where Growth Studios comes from.

Our Story

From the first online shop to a software studio.

Growth Studios didn't come out of nowhere. It's the result of ten years of operational practice, where we learned what digital projects actually fail at.

The beginning

The observation

At 16, Ivan builds his first websites and online shops. He notices something early: digital projects rarely fail because of the technology, but because of what sits behind it. Processes, data, operations. That observation becomes the foundation for everything that follows.

SEH

The team comes together

The founding of SEH Sports & Entertainment Holding brings together the team behind Growth Studios today. Over the following years, we take on multiple mandates including SK Austria Klagenfurt, FC Viktoria Berlin, GMC and top-10 heavyweight boxer Filip Hrgovic.

European League of Football
2021–2025

ELF

A league from zero

The biggest one: building the European League of Football. From an idea to a pro league with teams across several European countries, hundreds of thousands of fans worldwide and seven-figure operational revenue. We build everything a league needs to run digitally. Website, app, online shop, streaming platform powered by our own remote cloud TV production, ticketing, merchandise with logistics, B2B platform, single sign-on, fantasy manager, data platform and more.

The insight

What we learned

Across all those mandates, we see the same pattern: in almost every company, operations get improvised because the necessary tech know-how is either missing or unaffordable. Tools get duct-taped together, processes live in people's heads, data sits in silos. That's where the idea for Growth Studios comes from.

Launch

Growth Studios goes live. We build the operations infrastructure for growing companies that we needed and built ourselves in our own practice. Running more efficiently and unlocking new revenue streams, both from a single source.
