Core Banking Platform

Core banking platforms are the operational heart of every bank. They maintain the system of record for deposit accounts, loan accounts, and the transactions that move money between them. Every other system in the bank — mobile apps, ATMs, payment rails, lending origination, fraud detection — connects to the core. In the US market, three vendors — FIS (Horizon), Fiserv (Signature), and Jack Henry (SilverLake) — serve the majority of community and regional banks. These platforms were built in the 1980s and 1990s on architectures that were not designed for real-time processing, API integration, or cloud deployment.

Replacing a core banking platform is one of the most technically complex and risk-intensive projects in enterprise software. The core is live 24 hours a day, 365 days a year — every minute of downtime has direct financial and regulatory consequences. Customer account balances, transaction histories, and interest accruals must be perfectly accurate at all times. The data migration from old core to new core must be flawless — a single account balance error is a customer complaint, a class action risk, and a regulatory examination finding simultaneously. Most core banking migration projects take 3-7 years and cost nine figures.

Modern core banking alternatives — Thought Machine Vault, Temenos Transact, Mambu, 10x Banking — offer cloud-native architectures with real-time processing and API-first integration. But transitioning to these platforms requires engineering teams who understand both the technical migration challenge and the regulatory requirements that govern every aspect of the transition: data accuracy, customer notification, system availability, and regulatory reporting continuity throughout the migration. This is where most migrations fail.

We execute core banking platform migrations and integrations for financial institutions that cannot afford to fail the migration. Our teams understand core banking data models, the integration architecture between core and downstream systems, and the regulatory requirements that govern every phase of the transition. We approach core migrations as engineering programs with defined risk controls at every phase — not as consulting engagements that discover complexity after billing begins.
