Bastian studied communication design in Mannheim and has been working as a freelancer between design and programming for over 17 years. Next to (still!) being known for creating Zootool around 2008 he is known for developing the content management system Kirby. It wasn't always the case, that this was his sole project, but started as a side project while still working on customer projects. But what once started as a hobby or sideproject has now grown into a full-time job with a hand full of employees, selling worldwide and used by companies such as Daimler AG, Mozilla, the New York Times, many well-known names in the Web industry and universities such as Stanford or Harvard, just to mention a few.
