The companies listed operate in the Grand Est region, primarily within chemical manufacturing and wholesale building materials. While some are large groups like Air Liquide Healthcare, which provides home healthcare services and medical gases, and Lesaffre, focused on fermentation, the list also includes mid-sized firms. Soprema France specializes in innovative building products, and Butachimie produces Adiponitrile for plastics and textiles.
A notable pattern is the prevalence of companies in wholesale building materials, including KP1, a specialist in prefabricated building components, wienerberger France, providing building envelope solutions, and SEMIN, manufacturing construction materials. Many of these companies, such as Lesaffre, Soprema France, and SEMIN, have a long history, with founding dates stretching back to the late 19th and early 20th centuries.

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 12, 2026.
