Tamtam tracks 33 electronics and semiconductor companies headquartered in Lombardy. This list ranks all of them by number of employees on LinkedIn, led by Eldor Corporation, Technoprobe and Gewiss. Their median headcount is 312. Half of them were founded in 1983 or later. The most common headquarters are Milan (3).

This selection of electronics and semiconductor companies in Lombardy showcases a strong presence in automotive components and industrial automation. Firms like Eldor Corporation, MTA S.p.A., and Vodafone Automotive specialize in vehicle electronics and telematics.

## 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.
