The largest companies in Manche are primarily involved in government administration, food and beverage manufacturing, and industrial machinery manufacturing. These include established organizations like Département de la Manche, providing local government services, and Fondation Bon Sauveur de la Manche, a long-standing healthcare provider. The list features a mix of mid-sized firms and larger regional entities.
Notable companies include Les Maîtres Laitiers du Cotentin, which processes milk from local farms, and Elle & Vire - Groupe Savencia, a dairy cream brand with international reach. EFINOR specializes in metalworking and design, while TRICOTS SAINT-JAMES manufactures traditional knitwear. A common pattern is the strong presence of companies deeply rooted in the region's agricultural and industrial heritage, alongside public service institutions.

Tamtam finds the decision-makers at every company on a list like this one, with verified emails, phone numbers and the buying signals that tell you when to reach out.
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.
