Ruud Slenter
Founder,
Strategic Transformation Manager

IMPACTIVATE was founded by Ruud. After completing his studies in economic psychology at Tilburg University, Ruud held various commercial roles at leading companies such as L’Oréal, bol.com, and Unilever.
He later worked as an (agile) transformation coach, guiding dozens of teams and training hundreds of individuals to increase their impact. At Unilever, he successfully led agile transformations—first overseeing ways of working within the Benelux organization, and later taking global responsibility for the home care category.
Ruud’s background in psychology enables him to quickly understand and improve team and organizational dynamics. His commercial experience has given him deep insight into business operations—and what works (and what doesn’t).
Ruud is results-driven, easily connects with people, and brings a contagious energy that helps organizations, teams, and (senior) leaders make real impact.
