Since its founding, Tierre Group has based its growth and innovation on people, valuing teamwork, expertise, and the sharing of different points of view. To support constant and ambitious evolution, the company invests in its human resources by creating a collaborative environment and offering paths for both professional and personal development (technical and motivational training, and high-level consulting).

From this collective commitment and the definition of sustainable goals, the Map of Values was born: represented as the cross-section of a tree trunk, it symbolizes the company's history through its rings and identifies its values as the vital sap that guides its transformation, while keeping its identity firm.
