35 years as an entrepreneur: built a software company from scratch, scaled it across DACH, England, Asia and the Middle East, and sold it to private equity in 2022. Today I work with a small number of founders and growth companies as a board member, sparring partner and in exit preparation.

Who it’s for

Asking the right questions

I work with only a few companies at a time: those where my experience makes a real difference.

  1. 01Growth companies setting up professional governance for the first time
  2. 02Founders before or during a funding round or an exit process
  3. 03Mid-sized companies looking to expand internationally, especially into Asia or the Middle East
  4. 04Software and technology companies that want to scale operationally
  5. 05PE portfolio companies looking for experienced operational support
Services

Three roles. One stance.

I

Board seat

Regular strategic guidance as a formal board member. Entrepreneurial judgement on the board, not as a yes-man but as a critical partner.

Formal · long-term
II

Sparring & Mentoring

Direct conversations with founders and managing directors, no agenda, no euphemisms. Sometimes an experienced sounding board is worth more than any strategy.

Flexible · personal
IIIWhat sets me apart

Exit preparation

I sold my own company to private equity. I know what buyers examine, what pushes the price down and what comes after closing.

Before, during and after the sale
