Uni Systems is a pioneering Greek-owned ICT company founded in 1964 by Konstantinos Doxiadis. It began as one of the first IT ventures in Greece and has grown to become a leading provider of digital transformation services and solutions across Europe. The company has a long-standing commitment to facilitating the digital transformation of its clients by delivering dependable and innovative ICT solutions.

Following a significant merger in 2007 that combined the old Uni Systems, Decision Systems Integration, and Info-Quest’s Solution & Business Applications Business Unit, Uni Systems reshaped its strategic focus towards systems integration. This repositioning allowed the company to expand its service offering and strengthen its market presence.

Uni Systems is part of the Quest Group of Companies and maintains a substantial international footprint with operations in Greece as well as business entities in Belgium, Luxembourg, Italy, Romania, and Spain. It serves over 200 customers across more than 20 countries, supported by a workforce exceeding 1,800 skilled ICT professionals.

The company has an extensive track record in delivering large-scale, mission-critical solutions to various key sectors, including banking and finance, enterprise and utilities, public institutions, telecommunications, and EU institutions and agencies. Uni Systems offers a broad portfolio that ranges from enterprise infrastructure implementations to specialized vertical business applications and emerging technology solutions.

Dedicated to connecting business and IT seamlessly, Uni Systems aims to be one of the most reliable ICT systems integrators in the European market, fostering development and accelerating progress through technology.
