About me

Founded.Led.Sold.

I didn’t build my company from a lecture hall, but through daily decisions, crises, growing pains and real responsibility towards people and customers.

Today I support selected companies as a board member or advisor: with a direct view, without sugar-coating, and with a real interest in their success.
