Proud to be from Biel/Bienne

Even when it was known as Winox, the company supported the local hockey club HC Biel/Bienne. To this day, we remain united by values such as passion, emotion and attachment to the region.

This commitment is reflected in the role played by our CEO Patrick Stalder, who is co-chair of the club’s board of directors, continuing a tradition of local support and pride.
