The absence of a corporate design is actually a corporate design in itself.
Rudolf Zuendel founded the Freude - Hagmann und Zuendel advertising agency in 2003. The idea was to delight consumers with good communication, automatically creating happy customers and in turn bring delight to the agency itself. Until 2007 around 20 employees were providing support to clients such as one (telecommunications giant and one of the five largest accounts in Austria) and IKEA (furniture retailer).
The idea behind the corporate design was not to have any kind of corporate design at all. There were many different logos in an even greater range of colours and each employee had 25 different business cards - simple, colourful and exactly like the brand idea: delight.
