Reflex Is an Official Partner of the 2027 Handball World Championship

Plenty of power, maximum energy, and unconditional team spirit: When the 30th IHF Men’s Handball World Championship takes place in Germany from January 13 to 31, 2027, Reflex will be right in the thick of it as an official partner.

For Reflex, this commitment is far more than traditional sponsorship. “The partnership with the 2027 Handball World Championship is based on deep shared values. Like almost no other sport, handball relies on teamwork, trust, precision, and the ability to perform at the highest level under pressure—qualities that have also defined and distinguished Reflex for decades. Supporting this fantastic home tournament is a matter close to our hearts,” says Dr. Sandra Bell, CEO of the reflexGroup.

Volker Mauel, CSO of the reflexGroup, adds: “Germany is the foundation of our business and our brand. As we expand internationally step by step as a German company, this home World Championship allows us to show where we come from and what we stand for. Handball is a complex team sport that requires a high level of commitment and mutual trust. Those who can handle the pressure on the court will get the most out of it. We are fully convinced of the German team’s capabilities and ready to bring our energy into the arenas together with the fans.”

The 2027 World Handball Championship promises to be a thrilling sporting highlight. Exactly 20 years after the legendary “Winter Fairy Tale” of 2007, when the German team won the world title in the final in Cologne, the tournament returns.
