over 35 years of banking experience

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. In addi­ti­on, it cal­cu­la­tes taxes for Ger­ma­ny and other Euro­pean coun­tries in real time.
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.
