About us

Zuzi & Kerrin

We are two young entrepreneurs (one psychologist and one engineer – it turned out to be a good combination, after all). We believe in courage and kindness in the business world, in supporting collaboration in teams and in reading four books at once. We work with companies, teams, and individuals that want to have a better understanding of themselves and their team interactions. In a nutshell, we create an environment to connect.
