The manufacturers in Aargau are primarily well-established, mid-sized to large enterprises, many with a global presence. Key players include Franke Group, a global supplier of kitchen products; Omya, a producer of industrial minerals and specialty chemicals; Hero, a global company manufacturing nutritional food products; and Siegfried, a contract development and manufacturing organization for pharmaceuticals. The list highlights a strong base of traditional manufacturing, with a focus on food, chemicals, and industrial goods.
A notable pattern among these companies is their long-standing history, with several founded in the late 19th century. For example, Omya was founded in 1884, Hero in 1886, and Siegfried in 1873. This indicates a region with deep industrial roots and a legacy of sustained manufacturing operations.

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.
