Akbank Goes Live on Mambu Core in Germany

WHY THIS MATTERS:

Core banking modernisation is increasingly about more than replacing legacy systems—it’s about rebuilding the operational and data foundations that regulators, customers and cross-border business models now demand. For EU-licensed banks, cloud-native cores must deliver day-one stability, real-time reporting and airtight reconciliation, not just long-term agility. This go-live reflects a broader shift toward parallel transformation: upgrading transaction processing while simultaneously re-architecting data, reporting and controls. As banks expand across jurisdictions, the ability to operate with consistent, trusted data across accounting, risk and regulatory reporting is becoming as critical as the core itself. Successful modernisation is now defined by execution discipline and end-to-end readiness, not just technology choice.

Akbank AG has gone live with a new core banking platform from Dutch core banking vendor Mambu and completed a parallel rebuild of its data warehouse and reporting capabilities, according to separate LinkedIn posts from project leads.

Akbank AG is the Germany-based subsidiary of Istanbul-headquartered Akbank. Operating under a German banking licence from BaFin, the division serves customers in Germany and the wider EU market, providing banking services and supporting cross‑border financial activity between Europe and Turkey.

The new Mambu core banking platform runs on Microsoft Azure, with Innovance Consultancy acting as implementation partner for the production go-live, supported by Akbank Teknoloji (AkTech) – a specialised technology unit launched by Akbank in March last year – and additional partners for integrations and controls.

Announcing the project on LinkedIn on 30 January, Mehmet Ali Ozcan, managing director at Innovance Consultancy, writes: “I am happy to share that the core banking platform at Akbank AG is now live in production, marking a major operational milestone in its transformation to a modern, cloud-native architecture.”

He adds: “Delivered by Innovance Consultancy on top of Mambu and Microsoft Azure, this platform was brought live with a strong focus on operational stability, data integrity, and day-one readiness.”

Ozcan describes the go‑live as bringing together “multiple critical workstreams” across data migration, end‑to‑end validation of daily banking operations and end‑of‑day processes, and alignment of accounting reconciliation and reporting. He characterises the outcome as “a strong reflection of disciplined execution, shared ownership, and close collaboration across all teams”.

In a separate update focusing on the data and reporting work, Fulya İnal, technical leader at Akbank, writes: “Following the successful Mambu Phase-1 go-live at Akbank AG, we’d like to spotlight the data warehouse and reporting transformation that helped make this milestone possible—enabling trusted, end-to-end operational and financial reporting from day one.”

Detailing this approach, she says: “We began with reverse engineering the existing landscape to understand legacy flows, critical dependencies and hidden business rules. From there, we addressed multiple technical challenges and built a new foundation from scratch that could support both cut-over readiness and stable post go-live operations.”

İnal explains how the transformation included data integrations across internal platforms and external touchpoints, a cloud data warehouse design and implementation, end-to-end operational and financial reporting layers, external integrations aligned to target patterns, migrations with controlled cut‑over scenarios, validations and reconciliations before and after cut‑over, and regulatory/statutory reporting foundations with control checks.

Looking ahead, İnal forecasts: “Phase-1 is now a solid baseline—not only for the next phases of the core banking journey, but also as a reusable data and reporting foundation that can support future integrations, migrations, validations and compliance-driven reporting needs.”

FF NEWS TAKE:

This milestone highlights how cloud core projects are maturing from experimentation to industrial delivery. The real test will come in subsequent phases as new products, integrations and regulatory demands are layered on. Watch for more banks pairing core replacements with full data and reporting rebuilds to future-proof cross-border operations.
