What Décider ensemble does

D\u00e9cider Ensemble is a French non-profit association (association loi 1901) and think tank founded in 2003 and headquartered at 77 rue de Lille, 75007 Paris, dedicated to promoting a culture of shared decision-making and participatory democracy in France and Europe. The organization operates as a unified multi-program platform rather than a software product, with core offerings including the annual Rencontres Europ\u00e9ennes de la Participation flagship conference (gathering 1,000\u20131,800 attendees across editions in Rouen, Rennes, Toulouse, Strasbourg), the Prix de la Participation awards program (formerly Troph\u00e9es, rebranded in 2023 with 120+ dossiers submitted in 2024 and 70 laureates in 2023), the Club des \u00e9lus locaux network for elected officials (launched in Mulhouse in 2020), publications, webinars and working groups, the Observatoire des civic tech de la d\u00e9mocratie num\u00e9rique, and a member-only Centre de ressources resource center hosted on a Webflow-based web platform with a mobile application (REP 2025) supporting event registration, personalized programming, and participant chat.

The business model is a hybrid membership-and-event revenue structure: annual membership dues (adh\u00e9sion) grant access to member spaces, the resource center, working groups, and networking, while event revenue is generated through registrations for the annual Rencontres (with a 20% group discount for 3+ simultaneous registrations from local authorities). Customer segments span local authorities and elected officials (the primary segment), participation and consultation professionals, and citizens/citizen organizations, with a go-to-market motion that is community-led \u2014 partnerships with institutional bodies (CNDP, CESE, CEREMA, ANCT, Banque des Territoires, OIDP, ICPC, Make.org) and corporate sponsors (EDF, TotalEnergies, SNCF R\u00e9seau, WPD, Systra) extend reach across the French and European participatory-democracy ecosystem. The organization is led by President C\u00e9cile Sornin and Vice-Pr\u00e9sidente et tr\u00e9sori\u00e8re Brigitte Fargevieille, and is registered under SIREN 49028729900047.
