These companies are contract manufacturers in North Rhine-Westphalia, predominantly mid-sized firms with a significant presence in industrial manufacturing, pharmaceuticals, and consumer goods.

Heitkamp & Thumann Group specializes in precision formed metal and plastic components, and dalli-group produces high-quality FMCG products in personal and home care.
A notable pattern among these companies is their diverse founding eras, ranging from the 19th century with Klosterfrau Group (1826) and dalli-group (1845) to more recent establishments like Cellex Cell Professionals (2001). This blend of long-established family businesses and newer ventures indicates a sustained industrial base 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 13, 2026.
