The largest companies in Seine-et-Marne operate in diverse sectors, with a notable presence in retail, logistics, and public services. Firms like BUT, a home equipment retailer, and Levis’Store, a general retail business, represent the consumer goods market. SeD specializes in transport and logistics, while Picard Surgelés is active in food and beverage manufacturing. Public entities such as Université Gustave Eiffel and Département de Seine et Marne also feature prominently among the largest employers. These organizations are primarily mid-sized to large firms, with a mix of established companies and some more recently founded institutions.
A recurring pattern in this selection is the significant number of companies involved in public service and administration, including higher education. Université Gustave Eiffel and École nationale des ponts et chaussées are key educational institutions, while Département de Seine et Marne and UGAP are involved in government administration and public procurement. This suggests a strong public sector employment base within the department, alongside significant private sector activity in retail and logistics.

Tamtam finds the decision-makers at every company on a list like this one, with verified emails, phone numbers and the buying signals that tell you when to reach out.
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 11, 2026.
