Tell us a bit about yourself and your background
I grew up in Gerlingen near Stuttgart and studied Banking and Finance (MBF) at the University of St. Gallen, including an exchange semester in the MBA programme at the University of Texas at Austin. I began my career in investment banking before joining the Berlin startup ecosystem. I helped build the logistics company sennder from an early stage to unicorn status, leading M&A activities, like the acquistion of Uber Freight, and financing rounds, like raising a Series D of $160m. Afterward, I founded a health-tech startup that was backed with over €3m by VCs and angels. Later I served in CFO roles at ShopApotheke’s digital subsidiary and the automotive software company Incari. Alongside this, I co-founded Tallow Naturals, a fast-growing natural cosmetics brand, together with my wife. We recently were part of "Die Höhle der Löwen" (German version of Shark tank) and secured an investment from Judith Williams and Frank Thelen.
What inspired you to found your company, and what is its focus or mission?
The idea came from a personal story: my wife struggled with skin issues for years, and none of the conventional products helped. She discovered tallow-based skincare in the U.S.—a 100% natural alternative that truly worked for her. We saw the opportunity to bring this concept to Europe and founded Tallow Naturals. Our mission: provide 100% natural, science-backed skincare for sensitive skin—built on minimalistic formulations that truly support the skin barrier.
How did the MBF programme influence your journey as a founder?
The MBF gave me more than a strong foundation in finance—it shaped how I think as an entrepreneur. It taught me to approach challenges analytically, make decisions based on data, and combine strategic thinking with financial discipline. The programme’s intensity also fostered a self-starter mentality that has been essential for navigating the uncertainties of building companies from scratch.
Which skills, insights, or experiences from the MBF have been most valuable in building your company?
A deep understanding of finance has been invaluable—especially for structuring funding rounds, managing growth, and making data-driven decisions. The MBF also trained me to quickly grasp complex business models and assess risks analytically. Beyond the technical skills, the programme instilled a rigorous, problem-solving mindset that I still apply every day as a founder.
What advice would you give to MBF students who are interested in starting their own business?
Don’t wait for the perfect idea or timing—start small and learn by doing. The analytical and strategic skills from the MBF give you a strong foundation, but entrepreneurship is ultimately about execution, persistence, and adapting fast. Surround yourself with people who complement your strengths, and don’t be afraid to take calculated risks early in your career.
