Our story

Leissner Data is one of the oldest IT companies in Sweden and has delivered innovative communication solutions for operators and organizations since 1969.

Over the years, Leissner has become a renowned company in the industry for our expertise and contributed to a number of standards and innovations in IP and telecommunications.

Leissner is part of a company group that also includes Götalandsnätet (using the brand Gotanet) – an established Swedish operator with a product portfolio that includes broadband, fixed, IP and mobile telephony to B2C and B2B. Gotanet is also mobile MVNE and offers MVNO/SP services to innovated operators.

Our vision is to contribute in breaking up the dominance of large telecom operators by delivering cost-efficient software and establish interoperability for new, fast growing independent operators.

We have developed all components that are needed by MVNE/MVNO such as PGW/GGSN, HSS/HLR, SMSC, GMSC, etc. These mobile core components can be installed on virtual servers with Linux.

Leissner’s strength is the flexible and customer oriented development of new and existing functionality for operators in the telecommunications industry. We have over the years maintained a good track record of delivering stable and secure software for telecom operators.

Leissner has offices in Trollhättan and Gothenburg, Sweden.
