# The 30 largest multinational companies in Madrid
Tamtam tracks 815 multinational companies headquartered in Madrid. This list ranks the 30 largest by number of employees on LinkedIn, led by Atento, Telef贸nica and FCC. Their median headcount is 17,667. Half of them were founded in 1960 or later.
The companies listed in Madrid are predominantly large multinational corporations, many founded in the mid-20th century. They operate across diverse sectors, including telecommunications, IT services, and various business and environmental services. Telef贸nica is a global telecommunications company, while Atento and Konecta specialize in outsourcing and offshoring consulting. FCC is a global citizen services company, and Prosegur focuses on private security solutions. Quir贸nsalud is a leader in healthcare, and Indra Group provides defense, space, and IT solutions. Many of these companies have a significant global presence, with operations spanning numerous countries.
A notable pattern among these companies is their strong representation in services, particularly business process outsourcing, IT consulting, and infrastructure. This indicates a concentration of expertise in supporting other businesses and public services. Another observation is the prevalence of companies with a long operational history, some founded over a century ago, such as FCC and Quir贸nsalud, suggesting a mature corporate landscape in Madrid.

## 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.
