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 :-).

For the start-up, we delivered a comprehensive package of UX services in just 4 weeks. Based on a target group analysis and the definition of the value proposition, we created the corporate design with logo development, color scheme, photo shoot and product website.. As the next project we will participate in the product design for the conference solution calina.MEET.
