SIV AG has been a success story since it was founded almost 25 years ago. Now 405 employees work here, a large majority of which are based at the head office in Roggentin in Rostock. Additionally, the company, which is also internationally established, operates the subsidiaries SIV Software-Architektur & Technologie GmbH, SIV Utility Services GmbH and SIV Bulgaria EOOD. In 2013, SIV.AG generated turnover of 33 million Euros.



When 30 year old Jörg Sinnig founded „SIV Service für Informationsverarbeitung“ in 1990, it was not initially clear that the company would make 27.7m Euros in turnover, as in 2010. The graduate naval architect was, however, also not interested in large sums of money. He just wanted corporate freedom which he had missed during his employment as a designer and programmer. After political reunification of East and West Germany, training sessions were initially made available in an improvised computer centre. Jörg Sinnig specialised in selling commercial software solutions for small and medium-size companies.

In 1992, the first screen templates of a commercial information system for the utility industry had already appeared. From then on, the focus was on the energy and water sector. In 1993, the company developed the Allgemeine Betriebliche Informationssystem, ABI for short, which was based on the relational Oracle database system, into a marketable product. In the same year and with the water and waste water association Seelow, the SIV also acquired its first customers from the supply and disposal sector In the year 2000, the company moved into its newly constructed company building in Roggentin at Rostock and changed itself to a public limited company (AG). Four years later, the new product generation kVASy 4 was introduced as a web-enabled industry solution consisting of the four cornerstones Billing, Finance, Technical Assets and CRM.

In 2012 the new product generation kVASy 5 was introduced. Thus the company was able to achieve a smooth and also long-term transition with its customers into service oriented architecture (SOA). In 2013, the first successfully implemented projects to introduce the new process-oriented Generation kVASy 5 were then launched, the benefits of which could be experienced not least in the new industry cloud. More and more international users are joining the growing German customer base. These are from Algeria, Bulgaria, Macedonia or the Russian Federation. At the same time, SIV AG works closely with partners which are organised in networks.



In 2006, SIV Software-Architektur & Technologie GmbH was founded, focusing on software architecture, technology, development environment and basic technology. As a specialist for future-oriented system architecture along with software and technology solutions in the JEE and Oracle environments, SIV A&T focuses on model-driven software development for the new product generation kVASy 5 and providing powerful tools for the simple and efficient administration of Oracle databases.

Furthermore, the subsidiary SIV.BG was founded with the focus being on software architecture, technology, development environment and basic technology. More than 2.85m customers were provided with customer service in a project with E.ON Bulgaria.

UTIPS GmbH, the third subsidiary, was founded in 2008. The focus here is BPO services based around utility industry processes. In 2012, the company was renamed SIV Utility Services GmbH.

Company culture

The self-financed organic company growth over many years has not happened by chance, but rather Jörg Sinnig can primarily put this development down to the commitment and team spirit of his employees. At the same time, the topic of „reconciling work and family life“ is a central issue. Therefore, the company pays all nursery costs for every employee after they have successfully completed their probationary period. If needed, employees can also take advantage of flexitime, shorter working days or even working from home in order to help further with the demands of family life.
