The practitioner
who writes.

I have spent twenty-five years at the frontier of enterprise technology — building revenue organisations in Germany, Switzerland, and across Europe for companies that were doing something that had never been done before in their category.

In 2015, I was one of the first salespeople in the German market to sell AI-driven cybersecurity to CISOs who had never heard the term in a vendor conversation. That experience — educating before selling, building trust before pipeline — became the lens through which I now write.

Today I am CRO at Open Systems, a Swiss AI-powered cybersecurity company. And between the board meetings and the deals, I write — about negotiation, leadership, AI, and what it means to be human in a world where machines are getting very good at being useful.

„The future belongs not to those who know the answers, but to those who ask the right questions.“

What I keep
thinking about.

Across eight books and twenty-five years, the same questions return. Not as problems to solve — but as tensions to hold.

I

The end of the knowledge economy

AI has made „knowing how“ a commodity. What remains irreplaceable is the ability to ask the right question, to sense what matters, to decide under ambiguity. This is not a threat — it is a liberation, if we are brave enough to accept it.

Das Ende der Wissensökonomie I & II

II

Negotiation as a human art

Customers do not buy products or services. They buy a change in their lives. The best deals are not won by argument — they are won by silence, clarity, and a deep understanding of what the other person truly needs to transform.

Das Verhandlungs-Manifest

III

Leadership is a daily decision

Not a title. Not a methodology. Not a KPI. True leadership shows itself in moments — in how you respond when things go wrong, in how you create the conditions for others to do the best work of their lives.

IV

The courage to say no

Every time we say yes when we mean no, we perform a quiet theft of ourselves. Boundaries are not selfishness — they are the foundation of authentic relationship, genuine focus, and the kind of work that actually matters.

NEIN ist auch ein Satz

Let’s think
together.

Whether you want to talk about a book, a keynote, a CRO challenge, or simply one of the ideas above — I read every message.
