Solving problems is teamwork

Complex problems in organizations are often less about technology than you may think. Our work is about thinking processes, the difference between emotion and facts, improve cooperation, communication and asking the right questions. In short: problem solving and prevention is about people. We work with that focus. Our goal: to inspire people to grow and to help them become more effective in their work. You can also see that in our culture: we are pragmatic, have a drive, are clear to each other and our clients, and like to keep it measurable and concrete.

What we value

We like to make the complex simple. We believe that problems are solved faster and more effectively if people work pragmatically and transparently. So don't expect thick reports or lengthy meetings, but clear agreements, a lot of interaction and working on issues that really play a role in your organization. In short: roll up your sleeves and enjoy working together. CoThinking!

What you can expect of us

We always provide overview and structure. In our services, in our methods and communication.

Our work only makes sense if it is effective in your organization. We link theory to practice, we always provide context and continue until the goal is reached. We prefer standing in the mud with you in stead of watching from the side-lines.

We believe in people and their ability to keep growing. We love helping people get the best out of themselves. We just say "you" and we are always curious about the stories, ways of thinking and structures within organizations.

We enjoy our work and hope it inspires and motivates you to become even better in your work. We go for active and energetic and share our enthusiasm about our expertise in blogs, during training and Events, on our website…. shortly in everything we do.
