Direct peers

• EPA Paris-Saclay: Public'aménagement establishment tasked with developing the Paris-Saclay urban operation (university, research, housing, economic zones). Highly comparable to SEMAVO in mission, public-sector ownership structure, and operational mandate for sustainable city-building around Paris.
• Grand Paris Aménagement: French public development operator (formerly AFTRP) executing large-scale urban planning, housing, and economic zone projects across Île-de-France. Directly comparable to SEMAVO as a publicly-controlled entity running master contracting ('maîtrise d'ouvrage') and real estate promotion for local governments in the same region.
• SADEV 78 (Société d'Aménagement et de Développement de Yvelines): SEM operating in Yvelines department adjacent to Val d'Oise, focused on urban development, residential promotion, and economic zone creation for local authorities. Closely mirrors SEMAVO's structure, geographic scope, and product offering within the Île-de-France SEM ecosystem.
• SEMIDEP (Société d'Économie Mixte Immobilière du Département de l'Essonne): Department-level SEM for Essonne providing urban planning, real estate promotion, and public construction. Direct functional peer to SEMAVO at the same departmental scale, sharing the same public-private ownership model and Île-de-France operating footprint.

Broad incumbents

• Vinci Immobilier: Real estate subsidiary of the Vinci Group active in French residential and commercial development, including mixed-use urban operations. Comparable on urban product type and Île-de-France exposure, though not a SEM-aligned public entity.
• Bouygues Immobilier: Major French real estate developer with a national footprint in residential and commercial property. Overlaps with SEMAVO on residential promotion and large urban projects but operates at significantly greater scale and as a fully private commercial enterprise.
• Nexity: France's largest private real estate developer with significant exposure to residential, commercial, and public-sector-adjacent development. Comparable on the real estate promotion and urban development side, though operates as a private commercial developer rather than a SEM-aligned public mission entity.
• Altarea Cogedim: French diversified real estate group active in residential, commercial, and mixed-use urban development with strong Île-de-France presence. Comparable on urban product mix and customer overlap with SEMAVO's economic zone and residential programs.

Others

• SCET (Caisse des Dépôts): Caisse des Dépôts subsidiary that federates 200 French SEMs, providing methodology, legal, and capacity support. Not a competitor but a strategic enabling platform whose expertise and network directly amplify SEMAVO's operational capacity.

Emerging players

• Foncier de France (Action Logement Immobilier): Action Logement's property development arm, focused on affordable and social housing delivery across France, including Île-de-France. SEMAVO holds a 2.07% stake in this entity and partners with social-housing peers, indicating operational overlap on residential promotion and public-purpose housing.
