This transformation marks a pivotal step in OYAK ANKER Bank’s digital strategy, enabling it to respond faster to market changes, launch new financial products with increased speed, and offer customers a seamless digital experience, while maintaining the highest regulatory and operational standards.

Powering the Future of Banking with Composable Architecture

At the heart of the transformation lies OYAK ANKER Bank’s strategic vision to modernize its core banking capabilities and deliver greater agility, scalability, and customer-centricity. To bring this vision to life, the Bank built its new digital core on Mambu’s composable banking platform, recognized for its powerful APIs, flexible product engine, and enterprise-grade resilience.

The implementation was led by Innovance, OYAK ANKER Bank’s exclusive technology partner, which designed and deployed the new architecture on Microsoft Azure. This cloud-native environment ensures regulatory compliance, uninterrupted operations, and faster go-to-market capabilities, enabling the Bank to serve both retail and corporate customers with speed, security, and confidence.

Mark Geneste, Chief Revenue Officer at Mambu:

“We are pleased to have played a crucial role in Oyak Anker’s rapid transformation to Mambu’s cloud-native core banking platform.

A Blueprint for Digital Banking in Europe

The successful go-live demonstrates that even highly regulated, mid-sized banks can adopt modern, flexible banking architectures without compromising on compliance, security, or stability.

With this new foundation in place, OYAK ANKER Bank is well positioned to scale its offerings, adapt to future market dynamics, and set a benchmark for digital resilience and customer focus in the German banking industry.
