# The 25 largest multinational companies in Castile and León

Tamtam tracks 25 multinational companies headquartered in Castile and León. This list ranks all of them by number of employees on LinkedIn, led by Antolin, Universidad de Salamanca and IE University. Their median headcount is 205. Half of them were founded in 1993 or later. The most common headquarters are Valladolid (3).

Multinational companies in Castile and León include a mix of industries, with a notable presence in automotive, food, and education sectors. For instance, Antolin specializes in automotive interior components, while Galletas Gullón is a European cookie manufacturer. Educational institutions like Universidad de Salamanca and IE University also feature prominently, alongside financial services provider Global Exchange Group and aerospace company Aciturri Aeroestructuras.

A significant pattern observed is the prevalence of companies with headquarters spread across various cities in the region, rather than being concentrated in a single urban center. This geographical distribution highlights a decentralized economic landscape, with key players like Laboratorios Syva in León and Grupo Siro in Venta de Baños contributing to the regional economy.

## 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.
