# The 50 largest companies in the Gers department

Tamtam tracks 88 companies headquartered in the Gers department. This list ranks the 50 largest by number of employees on LinkedIn, led by ECOCERT Group, Survey and Conseil Départemental du Gers. Their median headcount is 48. Half of them were founded in 1988 or later.

The companies listed in the Gers department represent a mix of established firms and more recent ventures, primarily focusing on agriculture, manufacturing, and specialized services. ECOCERT Group, founded in 1991, provides certification and consulting for sustainable practices, while Survey, established in 2003, coordinates services in the pipeline industry. Castel & Fromaget, a construction company, dates back to 1927, and Comtesse du Barry has been specializing in gourmet food products since 1908. The list also includes the Conseil Départemental du Gers, a local government body.

Many of these organizations, such as ECOCERT Group and Culture Vélo, operate within specific niches like environmental services and bicycle retail. A notable pattern is the presence of several companies headquartered in L'Isle-Jourdain, including ECOCERT Group, Culture Vélo, and Abrisud, suggesting a regional concentration of certain industries.

## 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.
