Replace or augment your core. Keep the source, the skills and the decision records. Build on twenty-five years of production, not on a blank page.
The same engine has run the structured-finance book of one of the world's safest banks since 2001.
Three of the four groups run in a demonstration tenant today. Corporate banking is in design. Each group is an account-type set on the same engine, and your own account type is one more.
Run the book your core platform handles badly, or run the whole book. Either way you hold the source, the tools and the decision records. No vendor lock-in.
Configure the engine for a market you know, keep the customer relationship, and price the capabilities you switch on. You know the legislation. We bring the engine.
Every operation is an API call: open accounts, post transactions, run schedules, take payments, issue statements, feed your general ledger. You keep building the front end. We run the part that gets teams stuck.
The licence includes the whole engine and the skills that maintain it. Your team extends it the way we do. Nobody else in this market ships the core.
How it works →A loan, its funding, the swap that hedges it and the fees around it, kept as one structure and accounted for in the legal entity that owns it. Most cores still cannot do this.
The model →Every account carries its currency and its calendars. Revaluation, business-day conventions and irregular schedules are the engine, not an add-on you buy later.
The primitives →Stage any number of changes across accounts, counterparties and settings. See the before-and-after and the forecast with the changes applied. Submit the set as one authorisation, and the approver signs the list itself.
Studio →Forecast an account to maturity with the same code that runs tonight's day-end. Back-date a correction and watch the ledger reconcile. Every figure traces to the events that made it.
Event sourcing →AI makes it look easy to build a ledger from scratch. It is not.
Financial servicing needs settled patterns: value dating, accrual, day-end, a sub-ledger that balances and feeds your general ledger, four-eyes control. Getting them right takes years and the mistakes surface at month-end. LedgerTM is a proven core with guarded development, and AI works on top of it, inside the rules.
Why not build it yourself →A clean interface is a mark of a clean model underneath.




Two demonstration tenants run today: a structured-finance book and a retail lending book, each with sample data.
The first production upgrade, moving the structured-finance book of one of the world's safest banks from the previous generation of this engine onto LedgerTM, is in progress. Code evaluation and hosted trials open with launch. If you want to see it before then, write to us.
