OUNDO Industrial Design // Interface Design was founded in 1991 by Petra Kurz-Ottenwälder and Max Ottenwälder. With a multidisciplinary and global approach, we design brand-specific, economically and aesthetically outstanding products and systems – including their user interfaces.

The development of corporate product design lines and their long-term support are among our core competencies. A broad technological expertise, socio-economic understanding of target audiences, and comprehensive knowledge in developing cost-neutral design solutions form the basis of our work.

Over 600 projects for more than 100 clients worldwide and 163 international design awards validate our approach based on the DIM Design Improvement Method.
