The Morbihan department hosts a varied group of companies with in-house R&D, predominantly mid-sized firms in manufacturing and food processing, alongside some healthcare and software developers. Companies like Cite marine specialize in seafood, Olmix develops natural agricultural solutions, and MGDIS provides software for data-driven decision-making. FONDERIE DE BRETAGNE produces iron castings for various industries, and Multiplast designs high-tech composite structures for competition and industrial uses.
A notable pattern is the strong presence of the food and beverage manufacturing sector, represented by companies such as Cite marine, Groupe JEAN FLOC'H, and Les Délices de St-Léonard - LDC. Another common thread is the focus on specialized manufacturing, from BCF Life Sciences' amino acid extraction to Sigmaphi Accelerator Technologies' particle accelerator equipment, indicating a regional strength in niche industrial applications.

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.
