Preparing your experience
Core replacement fails when it is treated as one enormous switch. We decompose it into reversible increments, each of which delivers value and can be rolled back before breakfast.
A core banking platform is the one system a bank cannot afford to get wrong. It holds the ledger, the product catalogue, the customer of record and the regulatory position — and it is usually the oldest thing in the estate.
We run core programmes as a sequence of reversible steps. Products migrate in waves. The old and new cores run in parallel with continuous reconciliation. Every wave has a tested rollback that takes minutes, not days.
Our teams have delivered against Temenos, Finacle, Flexcube, Mambu and Thought Machine, as well as in-house cores built on Oracle and mainframe. We are implementation partners, not resellers, so the platform recommendation follows the requirements rather than a commission.
Ranges observed across comparable engagements. Yours will be modelled against your own baseline.
What changes for the organisation, stated as outcomes rather than features.
Product-by-product waves with dual-run reconciliation, so exposure at any moment is a slice of the book rather than all of it.
A parameterised product catalogue that lets the business launch a new deposit or lending variant in days without a code release.
Event-driven posting, instant balances and 24×7 availability — no overnight batch window standing between the customer and their money.
IFRS 9, Basel III, AML and local central-bank reporting designed into the data model rather than bolted on afterwards.
A thin, fast core surrounded by composable services — so future change happens at the edge, not in the ledger.
Every way a customer or partner reaches the bank.
Channel-shaped APIs that never expose core internals.
Composable services around a deliberately thin ledger.
The ledger of record and everything that reads from it.
The platforms and standards we build and support in this practice.
A sequence designed so each stage produces something usable, not just a document.
Product catalogue, interface inventory and data quality baseline — the honest picture before anyone commits to a date.
Weighted evaluation against your actual products and volumes, proven with a paid proof of concept rather than a vendor deck.
Integration layer, event backbone, reconciliation engine and the first migrated product family in production.
Product families move in sequence, each with dual run, reconciliation sign-off and a rehearsed rollback.
Legacy interfaces retired, licences surrendered and archive obligations met — the step most programmes forget to fund.
