Prof. Hermann Simon defined the term “Hidden Champion” in 1990 for companies that are globally successful in niche markets. On April 27, 2021, the Marketing Club Köln-Bonn invited both Prof. Simon and the Verein Deutscher Hidden Champions e.V. to tell this German success story. More than half of the Hidden Champions are based in Germany. Three member-companies presented themselves during the event and explained how to become – and remain – a Hidden Champion. In addition to KARL DEUTSCH, the companies HAUS SCHAEBEN and ZWILLING from Solingen presented themselves.
