These foundations in Île-de-France primarily operate in healthcare, social services, and scientific research. They range from large established institutions to more recent organizations. For example, Servier develops pharmaceuticals, Institut Pasteur conducts biomedical research, Apprentis d'Auteuil educates disadvantaged youth, and Institut Curie focuses on cancer research and treatment.
A notable pattern among these foundations is their strong concentration in Paris, with many headquartered in the capital. Their founding dates span from the late 19th century, such as Institut Pasteur (1887) and Apprentis d'Auteuil (1866), through to more recent establishments like Institut du Cerveau (2010), indicating a long-standing tradition of philanthropic and public service initiatives in the region.

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.
