# 30 leading companies with in-house R&D in the Indre-et-Loire department
Tamtam tracks 45 companies with in-house R&D headquartered in the Indre-et-Loire department. This list ranks the 30 largest by number of employees on LinkedIn, led by Plastivaloire, Laboratoires Chemineau and Vermon. Their median headcount is 42. Half of them were founded in 1989 or later. The most common headquarters are Tours (6).
These companies in Indre-et-Loire are mainly mid-sized firms involved in manufacturing, with a strong presence in specialized industrial components, pharmaceuticals, and environmental technologies. Plastivaloire manufactures plastic components for motor vehicles, while Laboratoires Chemineau and DELPHARM TOURS develop and produce drugs and cosmetics. Vermon designs ultrasound transducers, and Socofer France specializes in railway maintenance and manufacturing processes.
A notable pattern is the concentration of manufacturing expertise, particularly in niche markets. Several companies, such as CBE, which creates steel moulds for concrete tunnel segments, and VLAD, a battery manufacturer for medical and industrial markets, demonstrate a focus on highly specific industrial applications. This indicates a regional strength in advanced manufacturing and specialized engineering.

## 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 13, 2026.
