The playhouse of service design.

We share a drive to solve today’s challenges through service design. Together with curious organisations we design meaningful services that people love to use. Koos is a group of friends, each with specific skills, that motivate each other to be brave, discover, challenge, make mistakes, learn, create and play. We grow confidence with ourselves and our clients to embrace uncertainty and complexity. This is why we are the playhouse of service design.

As a talented pianist and producer DJ with a developed musical taste, it is not always easy for him to sit in one room with our Guilty Pleasure Boy Band Boris, Pim and Jeroen.

In 2009 Robbert-Jan and Jules, sitting in a rooftop garden in downtown Melbourne with a glass of whiskey in their hand, got the idea to start a company. Now, nine years later, Koos has grown to a well known service design agency with over 20 employees, two international offices and projects all over the world. We have strong roots at the Delft University of Technology – yes, we love our analytical tools and design methods – but we are also the creatives, the guys and galls that boost a meeting with energy, ask tricky questions, and the last ones to leave a party.

We’re the last ones to leave your party
