With the OBS Banking Engine, DIE SOFTWARE Peter Fitzon GmbH is one of the leading providers of core banking systems in German-speaking Europe. Founded in 1983, the independent software company has around 135 members of staff at its locations in Ebersberg near Munich and in Zurich.
Private and commercial banks, brokers, asset managers and specialist banks use the OBS Banking Engine, which is characterized by the highest possible degree of automation and individually configurable functionalities. It maps the complete business spectrum of a bank: securities and portfolio management, account management and payments, treasury and credit transactions.

As an open system, the OBS Banking Engine links all business-relevant processes both within the bank and with customers, market participants, partners and regulators. It thus forms the central platform for digitizing all business processes.

sustainability and social commitment

For DIE SOFTWARE, sustainability and social commitment are part of the company tradition. With our social and societal commitment we want to show responsibility and give something back to society.

Sustainability: For us, sustainability means the responsible and careful use of resources. Our goal is to become a completely climate-neutral company as soon as possible. We initiated this process in 2011 and have begun to reduce our company’s carbon dioxide emissions. We do this in three successive steps: 1. we try to avoid emissions, 2. we replace climate-damaging energy sources with climate-neutral ones and finally 3. we compensate for unavoidable emissions.
  1. avoiding emissions: Since 2011, we have been reducing our electricity consumption per employee – from just under 3,000 kilowatt hours per employee in 2011 to 2,300 kilowatt hours in 2019, or around 24 percent over the eight-year period. The biggest lever in this event is the consistent virtualization of hardware, which reduces power consumption both in the data center and through the power-saving ThinClients at each workstation. Besides power consumption, travel is the second major lever for savings. Thanks to modern conference technology, we are holding more and more meetings as telephone or video conferences.
  2. substituting consumption: Since 2011, we have been using only electricity from renewable sources. When travelling, we try to switch from air travel to rail whenever possible. Since the trains of Deutsche Bahn are completely powered by electricity from renewable energies, these trips are climate-neutral.
  3. compensating: For many years, we have been offsetting some of the climate-damaging emissions from our air travel by our employees voluntarily contributing to CO2 certificates. The company has doubled the amount. From 2020, we will fully compensate all air travel. In this regard, we are working together with Atmosfair, a leading climate protection organization with a focus on business travel.
Corporate Social Responsibility: For 20 years, companies and employees have been supporting FortSchritt Verein zur Verbreitung der konduktiven Förderung e.V. association which supports children with cerebral damage. We were also able to make our contribution to “Leben bewegt e.V. association for the promotion of physical activity for children and young people and to the “Dreifußmodell” (three-foot model) of the St. Martin kindergarten.
Regional sports are also close to our hearts, which is why we have been sponsoring the Eiselfing volleyball club for years and have brought the Bavarian Beach Volleyball Championships directly to us in the Klosterbauhof in Ebersberg. We also supported the volleyball department of TSV Grafing and the Taekwondoverein Kirchseeon.
In the local art scene, we are involved through the foundation of local art prizes such as for the art association Die Sonntagsidee e.V. and the acquisition of art, such as a stone sculpture for the monastery courtyard in joint participation with residents and the city of Ebersberg.
