Stefan in a few words

I am a Berlin-based entrepreneur with a mission to drive the world forward. Having founded various tech ventures and consultancies over the past 5 years, I have gathered a broad range of experience in the development of digital products and sustainable business models.

Using the Design Thinking method, Business Model Generation, and Lean Management tools, I worked on various innovation projects ranging from service designs to mobile apps to digital platforms.

As a studied business economist, media manager, and mechatronics engineer, I always strive to see things not only from one but several perspectives. For me, building collaborative solutions and bridging seemingly opposing elements is the key to solve the challenges of today and tomorrow. I am passionate about technologies that aim to change the world, and I am always seeking new challenges to broaden my horizon.
