G.N.T. Information Systems S.A. was established in 1991, and from its first steps, it focused on the development of tailor-made software in various business sectors. Having more than 20 years of experience in analysis, design and development of small, medium and large-scale software systems, we can claim that we know how to discover business processes, re-design them if necessary, and transform a set of user requirements (often not very clearly stated), into a complete and useful system. Most of our projects fall in the telecommunications sector, although some of our people have been involved in projects we have undertaken in other fields (e.g. sports betting management, integrated payment systems, lottery game software etc.) Currently, we employ 30 highly skilled IT engineers, holding graduate and post-graduate degrees in their domain of expertise. Our long and successful record in completing complex software systems helped us establish longstanding business relations with most of the big Greek software companies. We have participated in joint projects with Intracom Telecom, Intrasoft International, Singular, IBM, Ericsson, Intralot, Hellenic Telecommunications Company (OTE), Oracle and several other companies.
