David Léaurant

President · ADN Ouest

Profile

Background

David Léaurant built his career in information systems, first at Vet’Affaires and then at Keolis Santé, before joining Groupe Réalités in 2018. There he became Director of Organization, Information Systems and Innovation, a position he has held for nearly seven years.

A member of ADN Ouest for more than ten years, he was elected president of the association at its general meeting on June 20, 2025, during the ADN Festival. He succeeded Safia D’Ziri for a four-year term at the head of a network that brings together 760 organizations and 4,800 digital professionals in Brittany and Pays de la Loire.

A Pays de la Loire native with strong ties to the region, he is focusing his term on three priorities: responsible tech, developing tomorrow’s skills and inclusion in digital careers. He is also stepping up ADN Ouest’s presence among stakeholders in both regions.

Perspective

Digital and GenAI credentials

David Léaurant heads the leading digital network in western France and oversees, day to day, the information systems and innovation of a major regional group. This dual role, leading a collective network while managing operations, gives him a demanding eye for an AI project’s technical soundness, its ability to fit into an existing organization and its relevance to the region’s businesses.
