These companies are the largest organizations with in-house R&D in Argentina. The list is dominated by higher education institutions and healthcare providers, alongside established industrial groups and some technology firms. Mercado Libre, for instance, focuses on digital commerce and financial services, while Techint Group is active in steelmaking and infrastructure. Universidad Nacional de La Plata is a large university with a strong research focus, and Hospital Italiano de Buenos Aires provides healthcare and medical education. GDM specializes in agricultural research and development, particularly high-yield soybean varieties.
A notable pattern is the strong presence of educational and medical institutions, with six universities and three hospitals among the top fifteen largest employers. Another recurring theme is the long history of many of these organizations; several were founded in the first half of the 20th century, such as Techint Group (1945), Universidad Nacional de La Plata (1905), and Hospital Italiano de Buenos Aires (1853), indicating a foundation of long-standing institutions.

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.
