The IT services sector in Hungary is characterized by a mix of large subsidiaries of international groups and established national players. These companies primarily offer IT and telecommunications services, digital transformation, and specialized software development. Deutsche Telekom IT Solutions HU, with over 4000 employees, is a major provider of IT and telecommunications services. 4iG Nyrt. specializes in digital transformation, while BCA focuses on process automation and AI monetization. Lufthansa Systems Hungária provides IT services for airlines, and NISZ Zrt. serves public administration institutions.
A clear pattern among these companies is their strong concentration in Budapest, which serves as the primary hub for IT services in Hungary. Most of these firms were founded between the mid-1990s and the late 2000s, indicating a mature yet continuously evolving market. Their services range from broad IT and telecommunications offerings to niche areas like AI monetization and specialized solutions for the energy sector, as seen with MVMI Zrt.

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 12, 2026.
