Our stories


As far as I can remember, I have observed group dynamics. As a child, I learned and played different roles to carve out a place for myself: sometimes in the stands; sometimes behind the scenes and more often than not, at the forefront to capture attention and feel loved.

Over time, as I struggled to be more and more recognized, I lost myself.

The discovery of cooperative and complex learning was a revelation for me. I saw it as a key to positively transforming group dynamics.

By seeing how it works in groups of all ages, by witnessing equitable relationships where everyone feels valued and important, and by realizing the impact of what a group was able to achieve with the cooperative approach, my relationship with others has gradually changed and I have found a way in life.

Driven by the insatiable thirst to spread this approach as widely as possible, I put all my heart into owning it, deploying it in various contexts (in class, in meetings, in civic committees, etc.) and training people who are interested in learning more about it.

When I met Mathieu, my life partner, we co-founded Mindstack.io. We walked together for a long time and reflected on various ways to spread the cooperative learning approach even more widely. After a lot analysis on our practice as trainers and consultants, Mathieu had the idea of using technology so that people could use the cooperative approach in a completely free and autonomous way.

We then gave up our trainers hats to give way to our creativity and together gave birth to Mindstack.io in addition to two inspiring beautiful children.

I am therefore more than ever driven by the desire to spread the cooperative approach as widely as possible to enable everyone to keep in touch with themselves, to shine with others and to collectively generate the best solutions to the current ills of the planet.



Human relations have always been a source of fascination for me. As a young person, I was introverted and observed the dynamics developing in the groups, without participating most of the time.

One day, however, I found myself caught up in this fear of others. At the age when everyone is socially thriving, I felt alone in the group. This fear of being heard has slowly turned into anxiety.

Despite the fact that in my student life I was constantly in a group, I was reluctant to create new connections. Later, I noticed that despite the great progress made in my personal life, my fear of speaking out resurfaced as soon as I found myself in a working group.

It was then that I realized that the 18 years I spent in school combined with my self-effacement strategy had negatively impacted my ability to achieve my professional goals. The way we experience our school years has a major impact on our professional life.

One question remained in my mind: could it have been possible to create a social academic experience that takes advantage of the fact that there are 30 of us in a class sharing the same objective?

The answer came when I met Andréanne, my life partner, with whom I co-founded Mindstack.io. She was completing her postgraduate studies in cooperative and complex learning and was implementing this strategy in a variety of settings.

I then realized that the cooperation of an entire group in solving a problem goes beyond learning. The cooperative approach allows for structured micro-interactions that encourage people to talk to each other in order to achieve their goals allowing them to progressively develop the communication skills that I lacked when I was young.

Knowing the situation of young people today and having had the privilege of observing the benefits of the cooperative approach in various settings, I firmly believe that allowing them to learn by cooperating can help to counter this feeling of isolation created by the current individual culture in school while allowing them to develop essential skills in tomorrow’s world.
