Our History

“To experiment is to imagine that an individual action becomes a Solidarity movement”.

Céline Degreef, CEO of Yumana, is convinced that collective intelligence is a great lever for companies’ growth and influence.

In 2015, she launched a Solidarity digital platform. Her goal was to promote new ways of working within the companies in order to accelerate change, push back the boundaries, and to simply increase solidarity and social impact!

Thanks to the Solidarity platform, employees are the actors of your solidarity initiatives.
