These companies with in-house R&D in Normandy are predominantly large and mid-sized firms, with a strong presence in manufacturing and healthcare. Key players include Sidel, which provides packaging equipment, and Faurecia R&D Center, a global automotive parts supplier. The region also features significant public sector entities like CHU de Rouen, a large hospital network, and Université de Caen Normandie, a historic educational institution.

A notable pattern is the concentration of industrial manufacturing, particularly in automotive components, with companies such as PURFLUX GROUP, a filtration solutions manufacturer, and GMD Stamping, which designs technical parts for the automotive industry. This indicates a robust industrial base alongside substantial public health and education infrastructure.

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.
