# 30 leading manufacturers in the Drôme department

Tamtam tracks 76 manufacturers headquartered in the Drôme department. This list ranks the 30 largest by number of employees on LinkedIn, led by HM.CLAUSE, AUTAJON GROUP and VALRHONA. Their median headcount is 165. Half of them were founded in 1975 or later. The most common headquarters are Valence (5), Romans-sur-Isère (4) and Montélimar (2).

The Drôme department is home to a diverse array of manufacturers, primarily comprising mid-sized to large firms. These companies span various sectors, from specialized industrial machinery to high-end food and beverage production. This selection includes firms like HM.CLAUSE, a major player in vegetable seed creation, and VALRHONA, known for its sustainable cocoa and gourmet chocolate. Other notable companies are AUTAJON GROUP, a leading producer of packaging materials, and Crouzet, which manufactures mechatronic components for aerospace and other industries.

A significant pattern within these companies is the strong presence of the food and beverage manufacturing sector, with VALRHONA and Saint Jean focusing on specialized culinary products. Another recurring theme is the production of industrial components and machinery, exemplified by MONTEIRO’s high-tech welding services and SODIMAS, a French elevator equipment manufacturer.

## 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.
