About me


There is nothing more exciting than rebuilding and advancing a business!

25 years experience: living and working on four continents have shaped me.

Hands-on: Analysis and strategy are imperative, but success comes only through consistent implementation.

Consequent: Deciding for something also means doing something else later or not at all.

I am an international entrepreneur and executive: As an electrical engineer I have a broad and comprehensive understanding of technology and my interest in business administration led me right from the start of my career to the business side. Sales management and project management for huge international projects, often with volumens in the hundreds of millions of EUR were my main campus of fostering.

In 2009 I ventured into the photovoltaic industry. First at the global multinational Siemens in the USA and Germany, then as CSO for a medium-sized German company and currently as Managing Director Europe in a US start-up.
