Managing Director & Usability Engineer

Bettina Streit

I have been working with digital user interfaces for over 20 years and have been a certified usability engineer and user experience specialist for many years. In 2004 I founded coeno together with Markus Kugler. In my role as managing director I am responsible for new business, marketing and communication. My great passion is to exchange and discuss with people - about good usability, the return-on-investment for convincing user experience, the influence of outstanding design on usage and why coeno is the right partner for this :-).
