The Story in 30 Seconds

A fan app for Dinamo Zagreb, powered by real-time data

ShiftOneZero is a Croatian sports-technology company with over a decade of experience building high-performance apps for clubs and sports businesses. For its latest project it partnered with Dinamo Zagreb, one of Croatia's most prestigious clubs, to build a next-level fan experience: real-time match data, in-depth player statistics and interactive engagement tools.

The market was full of low-quality white-label solutions with shallow statistics and delayed updates. Founder Josip Bozic needed a football API that was reliable, fast, scalable and developer-friendly. Sportmonks stood out as technically superior and, from the first glance, one of the most affordable. He rates the support 10/10.

The Challenge

A fan experience is only as good as the data behind it

ShiftOneZero set out to build more than another app. The goal was a football fan hub where Dinamo Zagreb supporters could feel closer to the club than ever: live scores, in-depth statistics and interactive features like quizzes and predictions that reward fans for taking part.

That vision needs a robust data source, and the existing market did not deliver. ShiftOneZero found low-quality white-label solutions, generic apps with no personalization, shallow match statistics and inaccurate or delayed updates. For a real-time fan experience, delayed or wrong data breaks the illusion.

"We believe every club possesses its own uniqueness, from its history to its stadium, fan relationships, and identity. Our goal is to capture that essence and create a product that maximises what the club can offer."

What They Needed

The Results

A fan experience that exceeded the goal

Problems did come up, some from his own oversight and some data-related, but every time he got a sincere, honest answer, which he values more than insincere reassurance. He rates Sportmonks support 10/10: help that goes beyond regular responses to advice on implementation.
