The foundation of Les ateliers C stems from 20 years’ experience in setting up collaborative projects in the private and public sectors, in particular in the field of sustainable development. From her collaboration with multiple parties, Anne-Claude Cosandey realized the importance of creating a process that fosters the fluidity of the emergence of ideas and the convergence towards shared solutions. She then discovered the facilitation of collaborative dynamics and decided to train in this field in 2018 in Paris. Convinced by the virtues of the discipline, she created Les ateliers C in 2019.


With having people talk to each other, understand each other and listen to each other at their heart, les ateliers C offer tools for the reflective process and the resolution of complex problems through  collective intelligence. 

The company “Les ateliers C” support organizations in open innovation, project management, strategic thinking, consultation processes, partnership development.
