Martin Sternsberger MBA | Coach @ Yumi42

About me

30 years of entrepreneurship and leadership – as a founder, entrepreneur and executive. I've built two companies that run without me today. That gives me a foundation you can't learn from a book. And yet a solid education and a strong theoretical base for my coaching matter deeply to me.

What I see time and again with entrepreneurs and leaders: the real problem is rarely the strategy. It's the inner chaos. The thoughts that won't stop. The feeling that the business is running you – not the other way around. The pressure to always perform. And somewhere in the background, the question: is this really the life I want?

I work with people who sense that things can't continue the way they are. Or who simply want more – more clarity, more focus, more space for what truly matters: the business, the family, themselves.

My work connects mindset and strategy, inner attitude and concrete action. You won't get off-the-shelf tools or hustle & grind, but deep, genuine coaching – grounded in neuroscience and 3,000+ hours of training – from someone who has been exactly where you are now.

If this resonates with you, let's talk.
