Diagonale Ile de France

What Diagonale Ile de France does

Diagonale Ile de France is a French non-profit association founded in 1989 and headquartered in Juvisy-sur-Orge, Essonne (approximately 15 km from Paris). It delivers reception, prevention, and therapeutic housing services to people living with HIV and other severe pathologies, operating 80 places of Appartements de Coordination Thérapeutique (ACT) — a medico-social framework co-developed by the association and formally recognized under the 2002 law of social modernization. The organization was a founding member of the Fédération Nationale des Hébergements VIH (FNHVIH) in 1998.

The association runs three integrated service lines: a walk-in Accueil reception service with social worker availability without appointment, a Prévention service covering HIV/AIDS/IST awareness in schools (3ème classes), public spaces, and via downloadable brochures such as "Mortel Combat" and "Tous ensemble Changeons nos habitudes," and a Hébergement service that combines medical, psychological, and social accompaniment for ACT residents including children and single-parent families. A multidisciplinary team of physicians, nurses, psychologists, specialized educators, social workers, and early childhood educators supports residents in developing individualized life projects, with 76% of departing residents in 2020 transitioning to autonomous housing.

The business model is grant-funded rather than commercial: services are provided free of charge to beneficiaries, with revenue derived from institutional partners — primarily the Agence Régionale de Santé (ARS), the Conseil Départemental de l'Essonne, and a network of 17+ healthcare, housing, and social-inclusion partners (COREVIH Est, SFLS, Comité Relogement Essonne, Institut Gustave Roussy, Comede, La Cimade, Cultures du Coeur, Afrique Avenir, among others). Headcount is reported at 101–250 employees. The organization has no commercial pricing, no disclosed revenue figures, no funding rounds, and no M&A activity; its technology footprint is limited to administrative web infrastructure (WordPress site hosted by OVH, internet access in apartments since 2012) with no AI, proprietary software, or platform product.

Scale indicators7 records

Recent moves6 records

Expansion highlights5 records

Others

• FNHVIH: National federation of HIV and other pathologies housing organizations, of which Diagonale Ile de France is a founding member—sectoral coordination body rather than operator, but materially comparable constituency and policy role.

Direct peers

• Sidaction: French HIV/AIDS fundraising and grantmaking organization funding research, prevention and care programs including ACT-type operators; comparable HIV mission and beneficiary base but operates as a fundraiser rather than direct service provider.
• AIDES: France's largest community-based HIV/AIDS and sexual health NGO, providing prevention, screening and support services to people living with HIV—closely comparable mission and target population to Diagonale, though at national scale and with broader advocacy scope.
• ARCAT: Paris-based association supporting people living with HIV, hepatitis and sexually transmitted infections through medical, social and housing services—directly comparable medico-social housing and accompaniment model in the same Île-de-France region.
• Le Comede: Committee for the right to healthcare for migrants, providing medical and social support to immigrants including HIV-positive patients—Diagonale lists Le Comede as an existing referral partner, evidencing directly comparable population and care model.
• Basiliade: French nonprofit managing ACT-type therapeutic housing and medical-social accommodation for people living with HIV and other severe illnesses—closest direct operational peer to Diagonale's 80-place ACT service.

Emerging players

• Acceptess-T: Paris-based association supporting transgender people, including those living with HIV, through health, housing and social services—comparable vulnerable-population, HIV-related mission but narrower beneficiary focus.

Broad incumbents

• Médecins du Monde: International medical humanitarian organization running programs in France for vulnerable populations including migrants and people living with HIV—overlapping beneficiary base and prevention/outreach model but with a much broader health mandate.
• Fondation Abbé Pierre: Major French housing-focused association addressing homelessness and inadequate housing for vulnerable populations—including those with serious illnesses—overlapping housing-and-support model but with a much wider (non-disease-specific) constituency.
• Croix-Rouge française: Large national humanitarian organization operating medico-social housing, healthcare and emergency relief across France, including services to vulnerable populations overlapping with Diagonale's HIV/serious illness beneficiaries but at vastly greater scale and scope.
