Tamtam tracks 28 companies with a mobile app headquartered in Bulgaria. This list ranks all of them by number of employees on LinkedIn, led by A1 Bulgaria, DSK Bank and Postbank (Eurobank Bulgaria AD). Their median headcount is 507. Half of them were founded in 2000 or later. The most common headquarters are Sofia (22).
These Bulgarian companies with mobile apps are predominantly large established firms, with a strong presence of banking, telecommunications, and retail sectors. Companies such as A1 Bulgaria provide communication and entertainment services, while DSK Bank is a major retail and corporate bank. Postbank offers a range of banking products, and UniCredit Bulbank focuses on development opportunities. Yettel.Bulgaria is another telecommunications provider, and Aruba SpA, based in Italy, supplies IT infrastructure and cloud services across Europe.
A clear pattern among these companies is their concentration in Sofia, which serves as the headquarters for most of the listed firms. This indicates the capital city's role as a central hub for major businesses in Bulgaria, particularly in finance, communication, and retail.

## 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.
