Growth turns chaotic.
Structures don't keep up. Ownership becomes diffuse. Speed gets lost.
I sense what is really happening inside people, teams and systems — and accompany CEOs, founders and leadership teams with energy and without fear into new territory.
CEOs. Founders. Managing directors. Boards. Investors. Leadership teams in growth, transformation and crisis.
Structures don't keep up. Ownership becomes diffuse. Speed gets lost.
The direction is clear — but execution gets stuck in alignment and resistance.
Decisions drag. Energy drops. Roles are unclear or overlapping.
The shift from founder to leader needs new systems — and a sparring partner who understands both worlds.
The problem is rarely strategy. It's execution. That's exactly where I work.
In high-pressure phases clarity doesn't appear by itself. It has to be created deliberately.
I don't work through methods. I work through a recurring logic of effect — from pressure to performance.
Growth breaks down, transformation stalls, the team loses clarity. Pressure becomes constant. This is where every real movement begins — when the pain can finally be named.
Tensions become visible. Patterns get named. The unspoken finally hits the table. Clarity is not a mental product — it's the precondition for energy.
Roles get clarified. Decision spaces drawn. Ownership doesn't emerge from appeals — only from structures and trust.
Once clarity and ownership are in place, decision-making becomes light. Not because it's easy — but because it becomes tenable.
The problem is rarely strategy. It's execution. Here it gets properly organised — with pace, rhythm and consequence.
Clear movement creates new appetite. The team notices: we're actually shifting something. This is the point where leadership becomes joyful again.
No flash in the pan. But an organisation that stays operational under pressure. Clarity, ownership and energy — as a system, not as luck.
From confidential 1:1 sparring to structured programmes and keynotes that open rooms. Always practical. Always for impact.
A confidential thinking and decision space for CEOs, founders and managing directors. Continuous support in complex phases.
Programmes and workshops that strengthen leadership systems — before pressure builds, mid-transformation, or as recovery after crisis.
Talks on leadership under pressure, ownership culture, the serendipity mindset. Not loud. But activating.
As managing partner of a premium e-commerce company, I scaled Keller Sports past €100M. Hypergrowth, M&A, due diligence, restructuring. And in the end: insolvency.
Afterwards I deliberately paused. Coaching certification. Reflection. Personal rebuild. I know what it feels like when a professional identity collapses — and how clarity, ownership and movement come back.
That experience makes my work credible, close and deep. I have been on the other side. I know the reality you're working in right now.
As both an investor and coach/mentor, Marcus brings a very rare mix of top-tier advice and experience as a former CEO himself and the empathy and humour needed to properly open up.
By far the best keynote I have heard in a long time. Marcus saw our needs — and responded to them very individually.
His way of coaching is something special. He guides you with patience, humour and clarity to your own solution. Trust builds fast.
Marcus brings well-founded insights — and creates an atmosphere in which real learning and exchange become possible.
His combination of listening, targeted questioning and practical advice helped me reflect on my role as an entrepreneur.
Conversations about turning points, clarity and what nobody sees. My podcast with Katrin Hinzdorf (in German) — and selected episodes where I was a guest.
With Prof. Dr. Christian Busch on serendipity as a leadership skill — how leaders use the unexpected as a space of possibility instead of managing it away. (In German.)
My talk on the journey from hypergrowth CEO through insolvency, personal reset and rebuild — and what leadership under pressure really means. (In German.)
30 minutes. Free. Confidential. We look together where clarity is missing — and whether it makes sense to work together.
