Software for moneythat has to move.

Eight shipped platforms across payments, banking and investing. In this sector an outage is a regulatory event, so we build for reconciliation first and features second.

Where it usually breaks
01
Reconciliation

Ledgers must balance to the cent across providers, currencies and retries. Approximate is the same as wrong.

02
KYC and AML

Onboarding has to satisfy compliance without becoming the reason users abandon signup.

03
Provider dependency

Payment rails fail in ways you do not control. The system has to degrade without losing money.

04
Audit expectations

Regulators ask what happened on a specific date to a specific account. You need the answer in minutes.

How we approach it

Double-entry from day one, idempotency on every money-moving endpoint, and a reconciliation job that runs whether or not anyone is watching. We design the failure paths before the happy path.
