Glad you're here!
Tobias M. Zielke
Chief of Staff for Founders, CEOs and Investors
Hello, my name is Tobias Marcus Zielke.
I’m your next Chief of Staff or interim executive.
For nearly 25 years, I’ve been shaping and developing international companies – with structure, impact, and integrity.
Whether as CEO, CSO, COO or as the right hand to founders and managing directors:
I help startups, grown-ups, and established teams gain clarity about their future, master complex growth, and build structures that scale and endure.
- I love structure - but not bureaucracy.
- I like KPIs and dashboards - but not PowerPoint jugglers.
- And I prefer working with people who aren’t “playing career” - but truly want to make a difference.
People who genuinely care about impact.
I’m a builder, mentor, and motivator – with a strong sense of culture, a deep dislike for corporate buzzwords, and a dry sense of humor that often makes change feel easier than it is.
Transformation doesn’t need slides. It needs backbone.

Testimonials: What people say about working with me:
Throughout my career, I have been an employee, colleague, business partner, superior, sparring partner, mentor, or simply an enabler for many.
"If I were looking, you would be my first point of contact! An absolute recommendation for any company with growth ambitions."
"...You didn’t just lead with a strategic vision, but also with clarity, calmness, and a keen sense of your team. Taking responsibility, making decisions, and bringing people along – that’s what makes strong leadership. It was truly impressive to witness that up close."
"Despite my 10+ years of 'unemployment benefit' experience on my resume, you gave me the chance for a fresh start and consistently supported my growth. 17 years ago, you gave me the very first permanent employment contract of my life, and I certainly learned a lot from you on my way to leadership. Without you, I wouldn't be the person I am today. Thank you!"
"...Your employees are always a top priority. Masterful leadership is not a byproduct of the professional world. Personally, I know very few born leaders like you..."
"...You are one of the best mentors, coaches, and sparring partners one could wish for! Always straightforward, with a clear vision and compass for every phase. Any company or employee can look forward to having a Chief like you on board..."
"...You bring exactly what’s needed in the role of Chief of Staff: clarity, execution power, loyalty, and strategic understanding. Under your leadership, not only is efficient collaboration possible, but personal development as well – something I’ve experienced firsthand in my own career. Thank you for your support, the value you add, and the personal growth!
So, anyone looking for a trusted sparring partner on equal terms is in the right place with you..."
A look into my professional experience
Whether in Europe or internationally, my efforts have always been aimed at strengthening teams, building structures, and providing a solid foundation for companies. The system was never the sole focus – it has always been about the people who support it. I am now looking to continue this as Chief of Staff.
