About Marcus

Trust is not built by methods, but by clarity.

Since 2007 I have worked independently as a systemic business coach, consultant and trainer — today with a clear focus on demanding decision and leadership situations.

Before becoming self-employed, I spent twelve years as an employee in large corporate and consulting environments — among them Deutsche Telekom, T-Systems, Siemens AG and PricewaterhouseCoopers. That experience still shapes my work today: I know complex organisations, political interests, decision pressure and implementation reality not only from external consulting, but also from within.

My work combines corporate and consulting experience with systemic sparring, leadership development, personality assessment and AI-supported decision logic. My place is not that of the subject-matter expert, but that of the structured sparring partner for the decision process itself.

Stance

Clear on the matter.: I name what I see — including the uncomfortable parts.
Respectful in manner.: Clarity and respect are not a contradiction.
Structure in the process, not in the outcome.: I structure the path. The outcome stays yours.
No pseudo-answers.: An open question beats a quick, false certainty.
Responsibility stays with people.: Tools and methods help. You decide.

Methods & qualifications

Methods are tools, not an end in themselves. I use them where they genuinely move a decision or a development forward.
