My Background


I was born in Gunzenhausen, a small town in the South of Germany. For me it was always clear that I wanted to see the “Big World”.


I started my studies in Economics with a focus on Computer Science in Wilhelmshaven.


Sales / Accountmanager at T-Systems responsible for IP services


novomind AG: Sales, Customer Success, Project Manager, Business Unit Manager
In all these roles my passion was always to see things with the eyes of the customer and to be open for new chances.


I became a shareholder of novomind AG.


I became a happy mom of my son Freddy.


I was appointed to the Executive Board as a CMO/CSO responsible for Sales/Marketing and international expansion.


I decided it was time for a new challenge: STRealise and STInvest GmbH

Sylvia and I have worked closely together for over ten years. For her, customer requests have always been the starting point. With empathy and creativity, she developed solutions that could be implemented quickly and at the same time contributed to the strategic corporate goal.

Sylvia is full of energy and drive to get things done! She loves a little mission impossible and has a great sense for both the customer and the market perspective. Working with her means finding solutions and implementing them here and now: She is a real enabler who dives right into things instead of losing herself in too many discussions.

After years of working with Sylvia, I have gotten to know not only her “people skills”, but also her abilities as a catalyst: She gets things moving, brings people together and has a wide network. What sets Sylvia apart is her positive attitude and the ability to approach every challenge with good humor and a smile while implementing it professionally.
