These companies in Seine-et-Marne are primarily government administration entities, ranging from departmental councils to municipal governments and public commercial entities. They are mostly mid-sized to large organizations, reflecting the scale of public service provision. Notable examples include Département de Seine et Marne, providing diverse public services, and UGAP, the sole general public procurement center in France. Grand Hôpital de l'Est Francilien offers extensive medical care, while Mairie de Meaux manages urban development and public safety.

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 14, 2026.
