Showcasing innovative solutions
A dedicated space for territorial innovation in all its forms : its actors, ecosystem, and dynamics.
The program of the Arena is diverse to illustrate the variety of solutions, needs, actors, and initiatives: startup pitches to highlight solutions, reverse pitches by local authorities to express needs and realities, presentations and discussions on territorial strategies and actions, sessions featuring winners and awards dedicated to territorial innovation.
The Social Innovation Day
New this year
Wednesday, November 19, 2025, Hall 4
The 2025 “Salon des Maires” exhibition will spotlight social innovation, a key lever to address the social and environmental needs of territories.
Through a special day organized on November 19 in partnership with the “La France s’engage” Foundation, elected officials and local stakeholders will discover how the Social and Solidarity Economy (SSE) offers concrete, co-created solutions that generate collective value and respect the environment.
This day aims to strengthen the role of social innovation in upcoming municipal programs and raise awareness among all decision-makers about the opportunities offered by these new solidarity-based models.
