ASN Bank selects Ohpen for mortgage platform modernisation

ASN Bank has selected Ohpen as its strategic technology partner for mortgages as the Dutch lender accelerates efforts to modernise its core systems and standardise operations.

The agreement will see Ohpen deliver a fully integrated, cloud-native software-as-a-service (SaaS) platform spanning mortgage origination, servicing and credit management. The new system is intended to replace legacy infrastructure that has constrained operational efficiency, reporting transparency, and the bank’s ability to implement changes at pace.

The move forms part of ASN Bank’s broader ‘Simplify and Grow’ strategy, which focuses on restructuring processes, systems, and organisational design to support its core mortgage business. Implementation is expected to be completed by the end of 2027.

 Jan Lamber Voortman, Director Ohpen, said, “This is about more than replacing legacy infrastructure. It is about giving ASN Bank the agility, transparency, and operational efficiency required for the next decade. Cloud-native architecture, configurable product design, and unified data are no longer differentiators. They are foundations.”

The platform will introduce a unified data model and integrated data lake, enabling a single source of truth across the mortgage lifecycle. This is expected to enhance reporting capabilities, strengthen governance and support compliance in an increasingly stringent regulatory environment. Ohpen’s platform also carries annual SOC 2 certification, providing additional assurance around security and operational controls.

A key feature of the deployment is its configurability. The bank will be able to adjust product parameters within hours rather than months, increasing levels of straight-through processing and reducing reliance on manual intervention.

The partnership follows a competitive selection process amid growing momentum in the European banking sector towards platform consolidation and outsourcing of core systems. Banks are increasingly replacing fragmented legacy stacks with integrated SaaS solutions to improve agility, reduce costs and meet regulatory expectations.
