The Oise department hosts a concentration of family-owned companies, primarily in industrial machinery manufacturing, chemical production, and building materials. These are mostly mid-sized firms, with the largest having over 1,200 employees. Poclain specializes in hydrostatic transmissions, GEB SAS manufactures plumbing chemicals, and COBAT CONSTRUCTIONS is a family-owned construction company. Flexico offers flexible packaging solutions, while Prévoté Transport & Logistique provides transport and logistics services. WeylChem Lamotte is a French chemicals company.
A notable characteristic is the prevalence of long-established businesses, with many founded in the early to mid-20th century. Examples include GEB SAS (founded 1860), SAINTE LUCIE (founded 1885), and Rocamat (founded 1853). This indicates a strong tradition of generational entrepreneurship and sustained presence in the region.

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.
