This selection of research institutes in Spain mainly comprises large public universities, many of which were founded in the late 15th and early 16th centuries. These institutions engage in extensive research, often with international collaborations and a focus on generating and disseminating knowledge across various fields. Examples include Universidad Complutense de Madrid, a public university offering high-quality education and research, and Universitat de Barcelona, which has extensive research departments and projects.
Beyond higher education, the list also includes institutions like CSIC, a government agency focused on basic and applied scientific research across 126 centers, and Hospital Clínic de Barcelona, a public university hospital providing healthcare, research, and training. A notable pattern is the concentration of these large research institutions in major Spanish cities, particularly Madrid and Barcelona, which serve as central hubs for academic and scientific activity.

Tamtam finds the decision-makers at every company on a list like this one, with verified emails, phone numbers and the buying signals that tell you when to reach out.
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.
