These European organizations are primarily research centers and foundations, many with a focus on societal and scientific issues. They range from Fabrica, an Italian research center for creative talents, to the German Energy Agency (dena), which works on climate protection, and Chatham House, an independent analysis on international affairs.

## 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 14, 2026.
