These companies are primarily large and mid-sized firms in Lazio, with a strong focus on hardware manufacturing, particularly in the defense, aerospace, and industrial machinery sectors. Many were founded in the mid to late 20th century. Leonardo is a defense and security multinational specializing in aerospace and military systems, while Telespazio provides comprehensive space services. ELT Group leads in electronic defense systems, and Yokohama TWS is a global leader in sustainable tire and wheel solutions.
A notable pattern is the concentration of headquarters in Rome, indicating the city's role as a hub for these industries.

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.
