Jeroen's passion is to build people-centered organisations that focus on employee growth, learning and higher purpose.

In his young adulthood he played professional field hockey and studied psychology, but he missed a clear sense of purpose. He decided to quit his successful hockey career and founded his first company. Its goal: to help youngsters make decisions based on their strengths, passions and values. 

Later on he applied the knowledge of behavioural economics to help multinationals, NGO’s and the Dutch government, guide people to a sustainable way of living. While this challenge was more strategic, he soon discovered that engaging employees and building community was in no way different from helping youngsters with their life choices. People want to feel connected with a higher purpose and develop themselves around their strengths. He therefor strongly believes in the adagio ‘do good, to do well’ and the other way around.

If you hire people just because they can do a job, they’ll work for your money. But if you hire people who believe what you believe, they’ll work for you with blood, sweat, and tears.
