This list comprises government administration entities in Hauts-de-Seine, predominantly mid-sized to large organizations. Key players include Insee, which collects and produces statistics on the French economy and society, and ASNR - Autorité de sûreté nucléaire et de radioprotection, an independent authority controlling civilian nuclear activities. EPIDE Défense 2e Chance supports young people in reintegration, while CCI France federates French Chambers of Commerce.
A notable pattern is the presence of numerous city administrations such as Ville de Boulogne-Billancourt, Ville de Colombes, and Ville de Rueil-Malmaison, indicating a strong local government presence. These entities are spread across various municipalities within the department, reflecting decentralized administrative functions.

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 13, 2026.
