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. An internationally operating business conglomerate was set up by the teenager in no time.Lars Windhorst climbs up the career ladderIn the early 90´s Lars Windhorst began trading electronic components and computer parts and revealed great finesse in negotiating.The Business-Wunderkind always contrived to win the favor of the people surrounding him. At the age of 16 Lars Windhorst met 27-year-old Mellon Zhang who opened for him the doors to China and Hongkong. 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. In 1993 then 17-year-old Lars Windhorst founded Windhorst Electronics GmbH and became the Wunderkind of German economy. With cleverness and incisiveness he quickly put into practice what big industrialists loose sleep over.Lars Windhorst to make millions of profitShortly thereafter followed branches in China, Vietnam, and Europe.

With offices also based in Hong Kong the Windhorst group operated by 1995 in Germany, Europe and Asia to generate a turnover of 180 million Marks. In its second financial year the company of multi-talent Lars Windhorst translated more than twice as much into profits as in its first year. A mere 19 years old Lars Windhorst became Germany´s most successful entrepreneur. The young chief executive ran an international branch network of 20 establishments with over 200 employees world-wide.The Windhorst group and its operating areasAmong the most important business fields within the European area were the distributions of electronic components, the assembly of personal computers as well as the production of advertising films.His Asian companies conducted commerce with primary products and provided business consultancy and real estate business.
