We are now Nexum!

Dear Visitor,

In November 2019, proacteur decided to join forces with Nexum.

In response to the growing demand to support change projects, increasingly international in scope and diverse in nature, we sought a partner who shared the same ambition, vision and values.

With Nexum, we found a perfect match in geography, competencies, and above all, culture and values. 

Together we are the reference company for change management in Europe. 

Since March 1st, we are one big team, working under one banner: Nexum.
