Maarten also has a surprising energy level that he manages to convey in a very practical roadmap for us to follow.

Matthijs Tetteroo | Project Manager | The Boston Consulting Group

“Prof. Willem Verbeke is a world-class academic with a central and embedded position in corporate landscape. He did not only bridge science and business; he created a form of synergy that is unmet in academia. His research adheres to the highest academic standard top tier journals demand, while at the same time this research is answering questions senior executives face in everyday business. From a personal perspective, Willem is inspiring and fun to get along with and some of those academics to get in touch with in order to learn about new ideas that turn out to be high impact eventually.”
