A Real-Time Core for Digital Banks

Crassula gives a new bank a modern, real-time core: a single ledger, multi-currency accounts, payments, cards and products, with a Back-Office Dashboard to run it. Building greenfield or modernizing on top of an existing core, you skip the batch-driven legacy stack.

Where Crassula fits

Building a new bank

Run Crassula as your core from day one: real-time ledger, accounts, payments, cards and products on a modern stack, with no legacy to migrate.

Greenfield core, live in weeks

Modernizing an established bank

Keep your system of record and run Crassula as the orchestration and product layer on top, adding a real-time digital channel without a rip-and-replace. We complement the big vendor cores rather than replacing a tier-one system.

A digital layer, no cut-over

What the core covers

Real-time ledger

A single source of truth for balances and postings, updated in real time with full transaction history.

Accounts and products

Multi-currency personal, business and omnibus accounts, virtual IBANs and interest-bearing Vaults.

Payments and cards

SEPA, SWIFT and UK schemes plus card programs, all posting to the ledger in real time.

Fees and pricing

Price lists, per-product tariffs and mark-ups configured without engineering, applied by the core.

Back-Office Dashboard

Operations, reporting, transaction approvals, access roles and reconciliation in one console.

API-first

Everything the core does is exposed over a documented API, so your product and channels build on it cleanly.

One ledger, updated as money moves

Every payment, card authorization and internal transfer posts to a single real-time ledger, so balances are always current and each transaction carries its status and full history.

  • Real-time balances, no overnight batch
  • Completed, pending and canceled states on every posting
  • Full audit trail for reconciliation and reporting

Multi-currency accounts on the core

Hold many currencies on one account, each with current, reserved and available balances, and open personal, business or omnibus accounts with dedicated and virtual IBANs straight from the core.

Payments that post in real time

Move money over SEPA and SEPA Instant, SWIFT and UK schemes with routing that picks the right provider per transfer, currency exchange built in, and each payment posting to the ledger the moment it settles.

Run and watch the core from one console

Your team approves transactions, sets access roles, manages price lists and reconciles from the Back-Office Dashboard, and watches volumes, users and conversions on live charts.

Everything the core does, over an API

Accounts, transfers, cards, limits and reporting are all exposed over a documented REST API, so your apps, channels and partners build on the core cleanly instead of raising vendor tickets.

Free migration from your current core

Moving off a legacy or first-generation core? Crassula migrates you for free and can run alongside your existing system, so you modernize in stages instead of betting the bank on a single cut-over.

FAQ

For a new or challenger bank, yes - Crassula provides a modern real-time ledger, accounts, payments, cards and products you can run as your core. For a large established bank, Crassula is best used as the orchestration and product layer on top of your existing system of record, not a replacement for a tier-one core like Temenos or Thought Machine.

A greenfield launch on Crassula takes weeks, versus the 18-36 months typical of a traditional core program. Modernization projects that run Crassula alongside an existing core are staged, so you avoid a single high-risk cut-over.

Yes. Crassula offers free migration from your current core banking system and can run in parallel during the transition, so operations keep running while you move.

Yes. Every core function - accounts, transfers, cards, limits, reporting - is available over a documented API, so your apps, channels and third parties integrate cleanly.
