In the beginning of the 1990´s Lars Windhorst was said to be Germany´s number one business founder and a unique example for entrepreneurial spirit. He was hailed as the "Wunderkind" of German economy and Ex-Chancellor Helmut Kohl was pleased about the economic offspring of Germany. Until 1997 Lars Windhorst accompanied the former primeminister at business delegations abroad. Lars Windhorst started his entrepreneurial activities with electronic components which he imported from the Far East and assembled to personal computers in Germany in order to sell them at profit.

The sales director of a Chinese electronics company quit his job without further ado, became Windhorst´s partner and accompanied him on his way in the Far East.
