My Passion

I enjoy moving above, on and under the water by heli flying, SUP, windsurfing and freediving. I like to travel the world and entertain my grandchildren as a ventrilo-quist.

My Mission

After 20 years in consulting and almost 20 years in the startup world, I have gained intensive experience with corporates and young companies. I passionately bring this experience to the founding, implementation and structuring of new business ideas. Young founders are close to my heart, corporates I support in finding their way in this often-new world for them.
