Good to know.
Do we need our own banking licence?
The banking licence stays with you as the bank. ARANDOO builds the software; securities and crypto can be connected via licensed partners.
Can we replace our existing core banking system?
Yes. Our migration framework takes over customers, accounts, balances, transactions and contracts through an adapter for your legacy system – with trial migrations and reconciliation.
Where does the software run?
In your data centre or your cloud, e.g. on Kubernetes or OpenShift. Operation and maintenance are with your team.
Do we have to introduce everything at once?
No. The platform is modular. Many clients start with one building block, such as onboarding or customer management.
