These foundations in Paris are primarily engaged in social welfare, healthcare, and research. They include large established organizations like Institut Pasteur, a biomedical research foundation, and Apprentis d'Auteuil, which educates disadvantaged youth. Institut Curie combines cancer research and innovative healthcare, while Hôpitaux Saint-Joseph & Marie-Lannelongue offers comprehensive hospital services. SOS Villages d'Enfants supports orphaned children, and Fondation Adolphe de Rothschild specializes in head and neck pathologies.

A notable pattern among these foundations is their long history, with many established in the late 19th and early 20th centuries. For instance, Institut Pasteur was founded in 1887, Apprentis d'Auteuil in 1866, and Fondation Léopold Bellan in 1884. This indicates a strong tradition of philanthropic and public service institutions in the city.

How this list is built

Every company on this list has a Tamtam company profile. The industry is the one the company gives on LinkedIn; categories such as SaaS or fintech are classified by Tamtam's AI from the company's website and LinkedIn page; and the headquarters city must match the company's own address. Companies are ranked by the number of employees on LinkedIn, and the list is refreshed every night. Classifications can be wrong, so treat the list as a starting point rather than an official ranking. Last updated Nov 12, 2026.
