Interact Global was established to be part of the new way of working


Our purpose is to help teams connect. We eliminate the hurdles that block a deeper understanding and appreciation of each other. This is achieved through customized workshops, facilitated conversations, team support and coaching.


Our principles

We want to be your trusted partner.

At Interact Global we are curious about your intention, not only your behaviour. To design your customized workshop, we listen deeply to understand you and your team. We create an environment where everyone will feel valued and provide different ways for participants to express their opinions.
