# The 100 largest companies in Bulgaria
Tamtam tracks 363 companies headquartered in Bulgaria. This list ranks the 100 largest by number of employees on LinkedIn, led by Ministry of Interior, A1 Bulgaria and Vivacom. Their median headcount is 475. Half of them were founded in 1999 or later. The most common headquarters are Sofia (74).
The largest companies in Bulgaria are predominantly large enterprises, with a significant presence of established institutions. This list includes major players in banking such as DSK Bank, Postbank, and UniCredit Bulbank, alongside telecommunications giants like A1 Bulgaria and Vivacom. The Ministry of Interior, a government agency, is the largest employer listed.
A notable pattern is the concentration of these large companies in the capital city. All the listed companies, with the exception of Aruba SpA which is based in Ponte San Pietro, have their headquarters in Sofia. This indicates a strong centralization of economic activity and corporate presence in the Bulgarian capital.

## 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.
