This selection of critical infrastructure operators in Liguria primarily features large organizations in essential public services. Notable examples include GNV, a European shipping company specializing in Mediterranean transport, and ASL 3 Genovese, a health and social care provider. Ospedale Policlinico San Martino and IRCCS Ospedale Pediatrico Giannina Gaslini are significant hospitals, while AMT manages multimodal public transportation in Genoa. ERG Spa is a major producer of renewable electricity.
A clear pattern among these companies is their concentration in Genoa, which serves as the headquarters for all the listed entities. The companies span various sectors, including maritime transportation, healthcare, utilities, and public transport, indicating a diverse yet interconnected infrastructure landscape in the region. Many of these organizations, such as Banca Carige spa (founded 1483) and Ospedale Policlinico San Martino (founded 1923), have a long-standing presence, reflecting deep historical roots in their respective industries.

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.
