13 August 2025
Leading cloud banking platform Mambu today announced that OYAK ANKER Bank GmbH has successfully completed a comprehensive, full-stack modernisation and migration of its core banking systems to the Mambu platform, making it one of Germany's most ambitious digital transformation projects, spearheaded by Innovance.
This groundbreaking initiative has replaced all of the bank’s legacy systems with a future-ready, cloud-native infrastructure powered by the Mambu core banking platform streamlining the bank’s end-to-end operations. With this transformation, OYAK ANKER Bank GmbH is now equipped to lead in a rapidly evolving digital banking landscape, offering faster innovation, better compliance, and seamless customer experiences.
As the exclusive technology partner, Innovance delivered the full migration of OYAK ANKER Bank GmbH’s legacy technology stack to the cloud, placing Mambu’s true SaaS core banking platform at the heart of the transformation. The result: a modern, API-first architecture underpinned by microservices and event-driven workflows — enabling unmatched scalability and agility.
The transformation journey was successfully delivered and included:
- Scalable, cloud-native core banking services powered by Mambu
- A brand-new, next-gen mobile banking platform
- A reengineered data warehouse designed to deliver timely insights and robust reporting
- A suite of cloud-native ecosystem applications tailored to business and customer needs
- Operations with enhanced resilience and security
From initial planning and system design to full implementation and go-live, OYAK ANKER Bank GmbH was able to transition without business disruption. Leveraging Mambu, Oyak Anker Bank GmbH has built and launched deposits and lending solutions catering to private individuals and businesses, including fixed-term deposits and personal loans, gaining increased flexibility to serve the needs of its customers, through the use of modern cloud technology. Mambu’s open API architecture played a critical role in the integration process, allowing the bank to connect seamlessly with third-party solutions, such as regulatory reporting systems, treasury management, and mobile banking platforms.
With core operations now fully migrated to the cloud, OYAK ANKER Bank GmbH is already seeing measurable gains in operational efficiency and customer satisfaction.
Duygu Apaydın, Chief Technology Officer at OYAK ANKER Bank GmbH said “This transformation marks a major milestone in our digital journey. By moving our core banking systems to Mambu’s a cloud-native infrastructure, we have significantly increased our agility, resilience, and ability to innovate.

With Innovance as our technology partner, we were able to execute this transition smoothly and confidently — laying a strong foundation for the future of OYAK ANKER Bank GmbH.”
