DIE SOFTWARE is one of the leading providers of complete banking software in German-speaking Europe. Founded in 1983, DIE SOFTWARE is an independent software house with 130 employees located in Ebersberg near Munich and 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: from securities transactions with account and custody account management to foreign exchange trading and credit transactions to payment 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.

For 20 years, companies and employees have been supporting Fortschritt 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.

For us, sustainability also means the responsible and careful use of resources: a working group made up of management and employees works continuously to come closer to the ideal of "Green IT". When purchasing new workstation computers and servers, we pay attention to optimal energy efficiency. The power supply has already been converted to green electricity from renewable sources. An agreement on CO2 neutralization for business trips is being jointly supported by employees and company management, and many other measures have already been implemented.

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.
