What SEMAG does
SEMAAG (Société d'Économie Mixte d'Aménagement des Antilles-Guyane), formerly SEMAG, is a French mixed-economy public-private partnership (Société d'Économie Mixte) founded in 1986 and headquartered in Les Abymes, Guadeloupe. It operates as a regional territorial development company providing urban planning, land development, social housing construction and management, real estate programs (social rental, intermediate housing, assisted home ownership, public facilities, activity real estate), and tourism facility operation — including the Jardin Botanique de Deshaies. The company serves two primary customer segments: local and regional government authorities (collectivités) in Guadeloupe, Martinique, and prospectively French Guiana, and individual social housing tenants. Its technology stack centers on the SEMAAG & Moi tenant portal and an online rent/charges payment platform, complemented by a Synapse web services division offering RGAA accessibility audits, document dematerialization, website creation, and professional training.
SEMAAG generates revenue through three principal streams: recurring rental income from its social housing portfolio, professional-service fees for territorial development and urban planning mandates awarded under French public-procurement frameworks, and managed-services revenue from operating the Jardin Botanique de Deshaies tourist attraction. The company sells through direct institutional engagement with local collectivities, formal public-procurement processes, a digital self-service tenant portal for housing management, and on-ground proximity-agent teams providing field services to residents.
The company's go-to-market is sales-led and relationship-driven, anchored by 40 years of embedded local expertise in the French Antilles, physical offices in both Guadeloupe and Martinique, and the privileged SEM legal form that provides access to public development concessions, mandates, and assistance-to-mastery-of-work contracts. In 2024, SEMAAG executed a strategic rebrand from SEMAG to SEMAAG, signaling a repositioning from Guadeloupe-focused operator to a regional Antilles-Guyane territorial developer with active Martinique operations and planned expansion into French Guiana.

Company assessmentDirect peers
- ICF Habitat: ICF Habitat is the SNCF group's social housing subsidiary, managing a large portfolio of affordable rental properties across France. Comparable to SEMAAG as a French social landlord with diversified housing programs and tenant services.
- Seqens: Seqens is a French social housing operator combining property management, real estate development, and urban renewal. Its mix of housing management and territorial development activities closely mirrors SEMAAG's integrated offering across housing and urban planning.
- Vilogia: Vilogia is one of France's major social housing operators managing around 90,000 units, primarily in northern France. It compares to SEMAAG in social rental housing management, tenant services, and real estate development activities.
- Immobilière 3F: Immobilière 3F is a major French social housing operator managing over 250,000 units. It directly compares to SEMAAG in providing social rental housing, property management, and tenant services, though at significantly larger scale and primarily in metropolitan France.
- CDC Habitat: CDC Habitat is the social housing subsidiary of Caisse des Dépôts and one of France's largest social landlords. Like SEMAAG, it manages a substantial housing portfolio and develops affordable housing across French territories, making it the closest large-scale comparable in business model and customer base.
- Erilia: Erilia is a French social housing operator (bailleur social) managing rental properties and developing affordable housing, primarily in southern France. It is comparable to SEMAAG as a regional social landlord providing housing and tenant services.
- Territoires Publics: Territoires Publics is a Société d'Économie Mixte providing engineering, urban planning, and territorial development services to local collectivities in Brittany. It is highly comparable to SEMAAG as a regional SEM executing concessional development and AMO mandates for French local authorities.
- SADEV (Société d'Aménagement et de Développement de Saint-Denis): SADEV is a mixed-economy urban development company (SEM) operating in Réunion and Île-de-France on territorial development and housing programs. It is structurally analogous to SEMAAG as a regional SEM combining urban planning, real estate development, and economic development for overseas/regional collectivities.
Broad incumbents
- Nexity: Nexity is France's largest private real estate developer with activities spanning residential, commercial, and serviced housing. It overlaps with SEMAAG's real estate development business but operates at national scale across market-rate segments as well.
- Action Logement: Action Logement is the French national umbrella organization managing employee-driven housing funds and operating a large social rental portfolio. It serves a similar social housing mission across France and operates at national scale with a broader remit than SEMAAG's regional focus.
