# The 50 largest companies in the Haute-Marne department

Tamtam tracks 59 companies headquartered in the Haute-Marne department. This list ranks the 50 largest by number of employees on LinkedIn, led by F2J INDUSTRY, Ghm and Yanmar Compact Equipment EMEA. Their median headcount is 49. Half of them were founded in 1972 or later.

The Haute-Marne department features a mix of industrial companies and public service organizations. F2J INDUSTRY specializes in M&A operations for industrial excellence, while Ghm, established in 1837, focuses on lighting and urban furniture solutions. Yanmar Compact Equipment EMEA designs and manufactures compact worksite machinery, and 3P - PERFORMANCE PLASTICS PRODUCTS develops high-performance plastic and composite solutions.

Public sector entities like Conseil départemental de la Haute-Marne manage regional infrastructure and public services, and Centre Hospitalier de CHAUMONT provides healthcare. A notable pattern is the concentration of older, established manufacturing and public administration entities, with several companies like Ghm and Fonderies de Brousseval et Montreuil having been founded in the 19th century.

## 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.
