# Family-owned companies headquartered in the Isère department

Tamtam tracks 61 family-owned companies headquartered in the Isère department. This list ranks the 30 largest by number of employees on LinkedIn, led by Groupe SAMSE, ARaymond and Groupe King Jouet. Their median headcount is 117. Half of them were founded in 1945 or later. The most common headquarters are Grenoble (7), Saint-Quentin-Fallavier (4) and Vienne (2).

This selection of family-owned companies in Isère includes large and mid-sized firms, predominantly in manufacturing, wholesale, and transportation. Groupe SAMSE distributes building materials, while ARaymond designs fastening and connection systems. Vicat specializes in cement production, and Samat focuses on transport and logistics for sensitive products. GINEYS distributes food products, and Condat SA formulates industrial lubricants.

A notable pattern among these companies is their long history; many were founded in the 19th or early 20th century. This suggests a tradition of established family businesses in the region. Most are headquartered in Grenoble or nearby towns such as Voiron, L'Isle-d'Abeau, and Vienne.

## 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 13, 2026.
