Their median headcount is 359. Half of them were founded in 2005 or later. The most common headquarters are Madrid (23), Barcelona (6) and Alcobendas (4).

These Spanish companies are primarily IT services and consulting firms, ranging from large enterprises to mid-sized companies, with a strong focus on digital transformation and AI. Accenture España helps businesses and governments with digital transformation and data analytics, while VASS specializes in intelligent digital transformation, integrating technology, data, and AI.

## 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.
