These companies are contract manufacturers in Mexico, primarily mid-sized to large firms. Pharmaceutical manufacturing is well represented, with companies like PiSA Farmacéutica, which develops pharmaceuticals and healthcare services, Neolpharma SA de CV, focusing on high-quality medications, and CHINOIN Productos Farmacéuticos S.A. de C.V., which manufactures medications for human and animal health. Food and beverage manufacturing is also prominent, exemplified by BYDSA, offering corn, potato, and tortilla products, and Saljamex, specializing in processed meats.
The list shows a concentration of companies in the pharmaceutical sector, indicating a strong presence of contract manufacturing within this industry in Mexico. Another pattern is the diversity of headquarters locations across Mexico, rather than a single dominant hub, with companies based in Guadalajara, Mexico City, Azcapotzalco, and Zapopan, among others.

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.
