Our self -image
For us, private equity is not a pure financial transaction, but relationship work,
entrepreneurship and strategic foresight. We measure our success on what we are
in the long term for companies, people and generations.
We think in generations, not in quarters. Our origin as a family of entrepreneurs shapes our thinking - and gives orientation for tomorrow.
We are not anonymous investors, but real sparring partners. Long-term, honest and committed to entrepreneurs, teams and co-investors.
We invest with foresight - and help companies to grow strategically: structure, capital, expertise and entrepreneurial spirit.
Standstill is step back. We get new ideas on the way, drive innovations and actively accompany companies through change and growth.
Our decisions are based on deep understanding of markets, business models and operational challenges - and on clear, disciplined action.
We ourselves were First Mover, Game Changer, Seed Investors, we were start-up and grown-up. We were B2C, B2B and have become the market leader. That is why we know exactly how the DNA is composed of a successful company.
