À La Croisée des Mondes

A thought about the art of leadership where civilian and military worlds meet.


Every year, À La Croisée des Mondes is the opportunity we provide to delve into what makes great men and women, envision the company of the future, and, with several voices and several hands, prototype that desirable future.

Do you have to love to be loved? Where does self confidence come from? Is there such a thing as universal recognition? Does transmission happen without a framework for thinking? Why are role models so powerful? At what levels does the circulation of knowledge and power in organizations play out? Why is memory crucial?

À La Croisée des Mondes discusses management, bravery, commitment, excellence, and also transmission, to help everyone step back, think, be moved, and be even better at the art of leadership.

Its stance is having glances, sensibilities, professions, and the specialized areas of exceptional people meet to envisage management in all its complexity and nuances. The basis for this unconventional event is first of all the ambition to have two worlds that know little about one another meet: the civilian and military worlds. Then, hybridize the spheres further to let leaders from all different horizons bang their head against the wall and question what they’re sure of. Every À La Croisée des Mondes event is therefore an opportunity for us to delve into poetry, history, humor, science, music, philosophy, theology, sociology, and field work, to examine a heartfelt topic.

To complete a mission like this, we needed a first-class partnership. We found it in the world of the military.

We firmly believe that members of the military, starting with the French Navy, can teach us a great deal about leadership in the future. This is because military organizations, which do not have a business model, have as their only asset, the commitment of men and women. It’s because they turn out commitment. And it’s because when in training, in accompaniment, and when operational, they use extremely avant garde management, leadership, and command practices. It seemed obvious and necessary to us to shine a spotlight on them.
