How 433 Became the World's Largest Digital Soccer Community

Just about every soccer fan knows someone like this. That guy who steps up to take a free kick with just a little too much confidence. Shorts pulled up, legs spread wide—just like Cristiano Ronaldo always does. He shoots… miles over the goal. The 433 team posted this video on their Instagram account with a simple caption: “We all know a teammate like that.” Followers are tagging their friends en masse. The video is going viral.

A digital dressing room

Here’s how it works. One post, one joke, millions of views. It sums up how 433 has been building its empire for years. This online soccer dream began back in 2013 with a Twitter account created by Rogier Deelstra. But things really took off when the company also launched an Instagram account. “Of course, we’ve had the timing on our side. But we’ve also always thought big. Conquering the world—that was the goal from the very beginning. Our platform has really evolved into a kind of digital locker room, where fans experience soccer just as they do among themselves,” says Juul Manders. Along with former soccer player Demy de Zeeuw, he is one of the other founders of 433.

Playful formats instead of standard interviews

That explosive growth didn’t generate a single euro at first. In fact, in the early years, it was mostly about pitching to brands that saw the potential. Still, the founders were determined. Reach first, business second. “Attention has the leverage,” Manders says of that now. His platform’s revenue model doesn’t rely on traditional banner ads or logo placements; it’s all about so-called branded content. “Think of campaigns with Adidas, where players participate in playful formats instead of standard interviews. No questions about tactics, but quizzes and challenges. It’s not about the difficult question, but about who you are as a person.” That approach has proven to be a home run for years. Fans don’t tune out, and brands ride the wave of—the magic word in social media—engagement. “That’s how brand preference is created, and that’s what we believe in.”

Data analysts are driving a new approach

Still, maintaining success is often harder than building it. Especially in a world where algorithms and trends follow one another at breakneck speed. So how does 433 stay relevant? By starting over every single day. “Because the game is never over,” as Manders himself puts it. Behind the scenes, a massive push toward professionalization is underway, with data now playing a key role. The platform reaches hundreds of millions of people every month and generates billions of impressions. That requires structure. We now employ several data scientists. Beneath all that creative content lies an incredibly serious data-driven approach. Those insights make it possible to listen more closely to the fans and continuously optimize content.”

This strategy also opens up new commercial opportunities. For example, 433 knows exactly how many fans of clubs like Arsenal and Bayern Munich are on the platform, including their demographics and behavior. “We reach more Real Madrid fans than Real Madrid does itself,” says Manders. That makes targeted activations possible. Not a scattergun approach, but tailored campaigns. “We emphatically do not sell that data, but we use it to do fun things in a much more targeted way. This creates a new playing field for both brands and clubs, where reach and relevance come together.”

Amsterdam as a home base

433 has been based in B. Amsterdam for a year now. “We were looking for a new home that truly fits 433’s DNA,” says Manders. “Here, you can still really feel that raw startup vibe, with all those young companies and fun events. Plus, there are the padel courts, which are very popular with a significant portion of our approximately 50 employees. For us, the move has really been a bull’s-eye; that has pleasantly surprised me.”

The World Cup as a priority

And now the World Cup is just around the corner—the biggest sporting event in the world. For 433, this tournament is a strategic priority. “You have to win the match before it’s even played. Preparations started months ago. Major brands like AB InBev and Coca-Cola are jumping on board with campaigns. During the tournament itself, it’s all about balance. On the one hand, there’s a constant stream of soccer content; on the other, there are the branded collaborations. “We want to make it as relevant and fun as possible, so it doesn’t feel like advertising. Think of activations around the draw, interviews, and interactive formats. It’s all about the experience.”

Looking ahead, the bar is set high. 433 aims to continue growing as a media company, developing new platforms and an improved app. Another goal is to strengthen partnerships with clubs and players. “Entertainment and journalism are increasingly converging. We want to be at the forefront of that world. By continuing to experiment, innovating faster than the competition, and above all, by constantly listening to the fans. You have to stay eager to remain relevant. Always stay one step ahead.”
