These Barcelona-based companies are a mix of established groups and younger firms, largely operating in services and manufacturing sectors. Cellnex Telecom provides wireless telecommunications infrastructure, while TRADEBE specializes in environmental services and life sciences. SIMON designs electrical components and lighting solutions, and Planeta Formación y Universidades offers higher education. Lecta manufactures specialty paper, and GRUP MUTUAM provides healthcare and social services. Many of these companies have a global presence.
A notable pattern among these companies is the prevalence of older, established groups alongside more recently founded firms. For example, SIMON was founded in 1916 and GRUP MUTUAM in 1905, while Impress (orthodontic treatments) was founded in 2019 and Towa International (pharmaceuticals) in 2020. This indicates a diverse business landscape in Barcelona, combining historical industrial strength with newer ventures.

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 11, 2026.
