Fintech built on trust and rails.
Lending, payments and wealth platforms engineered for the rules they live under — tokenised, auditable and reconciled, so the regulator and the customer both stay confident.
In finance, the audit trail is the product.
We build money systems the way regulators wish everyone did: card data tokenised so it never lands in your scope, double-entry ledgers that reconcile to the cent, and an immutable record of every transaction. PCI, KYC and AML obligations shape the architecture from day one. The payoff is a platform that passes review quietly and a customer base that never has to wonder where their money went.
The sector, honestly.
Money software has no margin for "mostly works". A reconciliation that drifts, a card number stored where it shouldn’t be, a ledger that can’t be audited — in finance these are not bugs, they are liabilities with regulators attached.
We build regulated financial systems where compliance and correctness are the architecture: card data tokenised so PCI scope stays at SAQ A, double-entry ledgers that reconcile to the cent, and an audit trail on every movement of value.
The obligations that bind you — PCI, KYC, AML — shape the design from the first endpoint, so the platform passes review quietly and the customer never has to wonder where their money went.
Systems for fintech.
The platforms we ship most often for this sector — each scoped to a number the business actually cares about.
Payments & wallets
Tokenised card and account flows, payouts and reconciliation that keep PCI scope minimal and books exact.
Lending & credit
Origination, underwriting workflows and servicing with decisioning you can explain and audit.
Wealth & investing
Portfolio, trading and reporting platforms with the data integrity the numbers demand.
Ledgers & reconciliation
Double-entry ledgers and automated reconciliation so every cent is accounted for and traceable.
KYC / AML & fraud
Identity, onboarding and monitoring integrations that satisfy compliance without crushing conversion.
Embedded finance & APIs
Banking, payments and card rails exposed as clean, secure APIs for your own products.
Numbers, not slideware.
Every engagement is scoped to a measurable result. The kinds of outcomes we build fintech systems to move — and hold ourselves to.
The hard parts, handled.
The principles we build by in this sector — and what each one means once the system is live.
Scope kept minimal
Tokenisation keeps card data off your systems, so PCI burden stays at SAQ A instead of a full annual audit.
Correct, then fast
Ledgers reconcile and balances are provable — in money software, correctness is non-negotiable before speed.
Auditable by design
Every movement of value leaves an immutable trail, so a compliance review is a query rather than a forensic dig.
Regulation in the room
We design around the PCI, KYC and AML obligations that bind you before we write the first endpoint.
From startups to scale.
The kinds of teams across fintech we partner with — each with different stakes, the same standard of craft.
Chosen for the problem.
Framework-agnostic, outcome-opinionated. A representative stack for fintech — the mix bends to your problem, never the reverse.
One team. Zero hand-offs.
The CODT disciplines we most often combine to build for fintech — same architecture, same engineers, no integration tax.
Questions, answered.
The things buyers in fintech ask us most. Anything else — put it in a brief, a senior engineer replies within a business day.
How do you keep PCI scope manageable?
By tokenising card data through compliant providers so raw card numbers never touch your systems — keeping you at SAQ A rather than a full PCI audit.
Can you build lending or underwriting logic?
Yes — origination, decisioning and servicing with explainable, auditable rules, integrated with the data and identity checks you rely on.
Do you handle KYC and AML?
We integrate identity, onboarding and transaction-monitoring providers so compliance obligations are met without wrecking the signup funnel.
How do you guarantee the books are right?
Double-entry ledgers and automated reconciliation, with an immutable audit trail on every movement of value — correctness is the first requirement, not a later one.
Can you expose our finance features as APIs?
Yes — we build embedded-finance and payments APIs that are clean, secure and documented for your own products to build on.
