Finnova is a Swiss core banking system for banks, offered by finnova AG Bankware, a company based in Lenzburg, Switzerland. Banks use it to run their core banking processes. In September 2026 Swisscom announced that it would operate the Finnova core banking systems on Oracle Exadata Cloud@Customer, with infrastructure running entirely in Swisscom data centres in Switzerland.
The company is based in Switzerland, an EFTA state outside the EU. For a European bank, the questions are where core banking data is hosted in each deployment option, which operator runs the service, and how the contract governs access by operators and other parties involved. Finnova is not published as open-source software. A bank considering the system should have these arrangements confirmed in writing beforehand, and should also check how data can be handed over if it later moves to a different system.
