Sedia

What Sedia does

Sedia is a French Société d'Économie Mixte Locale (local public development company) founded in 1958 and headquartered in Besançon, providing territorial development, urban planning, construction, real estate promotion, and property management services across the Doubs, Haute-Saône, and Jura departments of Bourgogne-Franche-Comté. The company operates as a "grappe" (collective) of integrated entities — including Aktya, PMIE, Territoire 25, Expansion 39, Action 70, SPL Grand Dole, and D3B — collectively managing 339,250 m² of business and commercial real estate and developing large-scale mixed-use projects such as Technoland II (178 ha), TEMIS Santé (14 ha biomedical technopole), Innovia (70 ha environmental technology zone), and ZAC Hauts du Chazal (955 completed homes). Technical capabilities center on BIM (Building Information Modeling) digital project methodology, R2S (Ready2Services) smart building certification, and early adoption of RE 2031 environmental standards across residential developments.

The business model combines four revenue streams: development operations management (concession and mandate fees from public sector clients), property rental management (managed services fees on 339,250 m² across affiliated entities), construction and development services (professional services for feasibility, programming, and project delivery), and real estate promotion (transaction fees on residential and commercial property sales). Sedia serves four primary customer segments: local governments and public institutions (primary, via enterprise field sales through public procurement), professional/business clients (commercial real estate), individual home buyers (direct-to-consumer for residential apartments and land parcels), and public building operators. Distribution is direct via named commercial contacts per territory and asset type, supplemented by website listings (14 professional, 12 individual offerings), LinkedIn presence, and public procurement channels. Revenue is undisclosed; the entity operates under a public-private ownership model with no external funding rounds identified.
