# The 50 largest companies in the Eure-et-Loir department

Tamtam tracks 225 companies headquartered in the Eure-et-Loir department. This list ranks the 50 largest by number of employees on LinkedIn, led by Eurofeu, Groupama Centre Manche and Crédit Agricole Val de France. Their median headcount is 138. Half of them were founded in 1985 or later. The most common headquarters are Chartres (21).

The Eure-et-Loir department features a mix of large and mid-sized companies, with a notable presence of financial services, government administration, and specialized manufacturing firms. Eurofeu, for instance, is a major player in fire safety, while Groupama Centre Manche and Crédit Agricole Val de France are significant in insurance and banking. NoveoCare manages various health and retirement contracts, and CAR LOVERS is an automotive distribution group.

A clear pattern emerges with a strong concentration of headquarters in Chartres, including several administrative bodies like the Département d’Eure et Loir and Chartres métropole, alongside financial institutions. This indicates Chartres' role as a central hub for both public services and corporate operations within the department.

## 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.
