# 30 leading e-commerce companies in Buenos Aires

Tamtam tracks 53 e-commerce companies headquartered in Buenos Aires. This list ranks the 30 largest by number of employees on LinkedIn, led by Mercado Libre, COTO and Dia Argentina. Their median headcount is 759. Half of them were founded in 1997 or later.

These e-commerce companies in Buenos Aires primarily encompass large and mid-sized firms specializing in retail, food and beverage services, and internet publishing. Notable examples include Mercado Libre, an internet publishing company, and COTO, involved in international trade and development. Frávega focuses on appliance sales, while Blue Star Group (BSG) offers jewelry and accessories. The list also features Dia Argentina, a proximity store network, and Café Martínez, a family-owned coffee importer and distributor.

A significant pattern observed is the strong presence of established companies, with many having been founded in the early to mid-20th century. For instance, Frávega was founded in 1910, Grupo BGH in 1913, and Café Martínez in 1933. This indicates a mature e-commerce landscape in Buenos Aires, supported by long-standing businesses adapting to digital channels.

## 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.
