He often travels the world to visit suppliers and customers, and to find inspiration in new innovative products. Dümmel knows Asia inside out, but Northern Germany is the place he calls home. Since 2016 he takes part in the TV program “Die Höhle der Löwen” (literally: The Lions’ Cave, German version of Dragons’ Den on German TV channel VOX ) where he plays one of the “lions”, looking for young entrepreneurs with brilliant products.Ralf Dummel is very convincing with his genuine and appreciative style.

Dümmel is often on the road for professional reasons, and when he sees that a customer adds a DS product in their shopping cart, he feels the same tingle of joy after 28 years that he felt in the early days. The 400 employees are Dümmels’s most important asset. They actively take part in the company, invest themselves in it, and help it develop further.
