Diffuz is a Macif initiative created to support you in volunteering and respond to your desire to act for a better world.
Diffuz’s raison d’être is driven by these convictions:

✔ Anyone can volunteer.
✔ Every action counts.

And more concretely? Diffuz offers a free digital solution that allows associations and citizens like you to carry out solidarity actions together, called “challenges”.

But beyond a simple tool, Diffuz presents itself above all as the network of voluntary actions which brings together the “throwrs” of challenges on one side, and the “takers” of challenges on the other, to form a real engaged community.

You will have understood, our mission is to facilitate connections and taking action and thus, make volunteering accessible to everyone!


Born from the desire to respond to citizens’ desire to act and the needs of associations, Diffuz was designed for you, with you.

At the heart of the Macif identity, reflecting its values ​​of sharing, commitment and solidarity, Diffuz aims to be a springboard towards volunteering.

We have always been convinced that the desire to act lies dormant in each of us, that it needs to be guided, supported and valued.

Diffuz was therefore created to facilitate and make volunteering accessible to all, to bring about solidarity meetings and support the associative sector. This is how we can act positively, together, on the world around us.

By offering to organize and/or participate in solidarity actions near you, we are giving you the keys to contributing to the movement and taking your first steps as a volunteer.

Diffuz is a happy mix, an ode to commitment, a diversity of actions, it’s us, it’s you.
