# The 29 largest manufacturers in the Landes department
Tamtam tracks 29 manufacturers headquartered in the Landes department. This list ranks all of them by number of employees on LinkedIn, led by LABEYRIE FINE FOODS, POTEZ AERONAUTIQUE and Groupe Gascogne. Their median headcount is 52. Half of them were founded in 1980 or later. The most common headquarters are Dax (3).
The companies in Landes are primarily manufacturers, including food and beverage, wood product, and chemical manufacturing, with a mix of established large groups and mid-sized firms. LABEYRIE FINE FOODS is a European food group, POTEZ AERONAUTIQUE specializes in aircraft structural components, and Groupe Gascogne operates in wood, paper, and packaging. DRT develops products from pine resin, and Atlantique Automatismes Incendie (AAI) designs fire protection systems.
A notable pattern is the strong presence of companies founded in the early to mid-20th century, such as POTEZ AERONAUTIQUE (1916), Groupe Gascogne (1925), and LABEYRIE FINE FOODS (1946). This indicates a region with long-standing industrial roots, particularly in sectors like food production, wood processing, and specialized manufacturing.

## 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.
