Náš příběh

Why Complex?

We started with a simple idea - to combine elite athletic performance and modern science into supplements that actually work. We founded Complex in Prague in 2023 (Sebastian Rod, Filip Langer, and Honza Tobiška) because we were tired of a market full of compromises, confusing jargon, and empty promises.

Our goal is to deliver uncompromising quality with science-backed formulations for anyone who wants to push their limits — from elite athletes and entrepreneurs to everyone who wants to live life to the fullest.

Vývoj produktů

We were looking for supplements we could truly trust, but none of them convinced us. So we made our own. From day one, we’ve built Complex on what actually makes sense: top-tier quality, science-backed formulas, and an approach that isn’t just marketing - it genuinely works.

We create every product with one goal: to help you feel better, look better, and perform better. Today, our supplements are used by professional athletes, entrepreneurs, students, and anyone who wants to get the most out of themselves.

Our Founders

Sebastian Rod - CEO

Sebastian Rod is the co-founder and CEO of Complex. From day one, he has led the brand’s strategy, growth, and overall direction. He started building businesses while still in university, launching several projects that generated revenues in the millions of CZK. Those early wins gave him the foundation to build Complex into a brand that, in a short time, has become trusted by professional athletes, entrepreneurs, and students alike.

Sebastian grew up as a competitive athlete, and floorball taught him discipline, competitiveness, and a drive to push his limits. He brings those same traits into how he leads the company: a focus on performance, long-term thinking, and an unrelenting commitment to staying one step ahead.

His vision is to build Complex into the biggest supplement brand in the world.

Filip Langer - Logistics Manager

Filip Langer is a professional floorball player competing in Sweden’s top league (SSL) and a member of the Czech national team. Alongside co-founding Complex, he connects elite sport with the world of business. His goal is for the brand to be a partner for anyone who wants to become the best version of themselves.

On the field and beyond, he builds on discipline, science-backed strategies, and authenticity. At Complex, he oversees logistics and, as a content creator, inspires a broad audience — from professional athletes to anyone looking to take their performance to the next level.

Honza Tobiška - CPO

Honza Tobiška is the co-founder and Product Manager at Complex. He’s also a respected science-based lifestyle coach who works with elite athletes from the NHL, the Premier League, the Bundesliga, and the top Czech league. His clients include Patrik Schick, Antonín Kinský, Jiří Kulich, and David Jiříček.

As the youngest member of the renowned STACA institute, he provides comprehensive guidance in nutrition, sleep, supplementation, and recovery. Sport has been part of his life since childhood—intensive training in football and judo sparked his passion for performance optimization as early as sixteen.

Today, Honza reaches tens of thousands of people through social media, teaching them how to combine the latest scientific insights with simple, practical habits. His goal is simple: to help anyone take their performance and lifestyle to the next level.
