Sem agencia

What Sem agencia does

Sem Agencia is a mixed-economy urban development and project management company headquartered in Reims, France. It operates through a dual legal structure: a Société d'Économie Mixte (SEM) founded in 1990 with 13.5 M€ of social capital, 61% held by public shareholders (Grand Reims, Ville de Reims, Ville d'Epernay, Caisse des Dépôts et Consignations) and 39% by private shareholders, and a wholly-owned Société Publique Locale (SPL) created in March 2022 with 500 k€ of capital owned by Grand Reims and Ville de Reims. The SPL structure legally restricts the entity to working for its public shareholders on their territories, making it a captive in-house operator rather than a commercially marketed consultancy.
