Collage of startup success news cutouts

Our app suffered from feature creep and therefore lacked a top notch user experience. Sebastian helped us a great deal in creating better, cleaner user experiences with less distraction. He also had a huge impact on the general look and feel of our app, which looks slicker and more professional than it did before.

Florian Hassler
Florian Haßler, Founder of FRYD

I was sceptical if Sebastian would understand the complexity of our app but was very impressed by his skills and vision.  Our users love the design. Highly recommended. I love working with Sebastian and he is now my goto person for everything Design and UX related.
