Solutions by segment
Four buyers come to us. A startup chasing a licence. A live venue under load. A payments firm adding assets. A bank that must not get custody wrong.
The stack below is the same each time. What changes is where we start and who owns the parts you already run.
Same engineering group. Four starting points. Read the one that matches your board deck.
You have a licence path and a deadline. You do not have a matching engine, a wallet layer or a security review.
We build the core, then hand it over with the docs your auditor asks for.
Volume grew. So did the evidence your regulator wants. Both land on the same engineering team.
We split the load: one group hardens custody, another files the proof.
Your card and SEPA flows work. Crypto has to join them without touching PSD2 posture or settlement.
Ramps sit beside the rails, not inside them.
A retail balance is a promise. It needs custody, limits and a clean audit trail behind it.
We design the control layer first, then the screens.
Four layers. Each one has an owner, a test and a document. Nothing is left implied.
| Layer | What we build | What you can show | Detail |
|---|---|---|---|
| Access | Trading, wallet and ramp APIs with signed requests | Rate limits, replayable request log | Service scope |
| Ledger | Double-entry balances, one source of truth per asset | Daily reconciliation output | Delivery examples |
| Keys | Hot, warm and cold split with quorum approval | Signed policy and key ceremony notes | Custody build |
| Controls | Screening, limits and Travel Rule message flow | Case files an examiner can read | Compliance engineering |
The order never changes. Design before code. Evidence before launch.
Two weeks. We map the product, the licence and the risk that sits between them.
One written design. Services, data flow and the rulebook each choice answers to.
Senior EU engineers ship in two-week slices. You see running code, not slides.
Security review, load runs and the evidence pack. Then launch and 24/7 cover.
The engineering standard is fixed. Only the commercial shape moves.
A defined product, a defined price. Best when the spec is settled.
A standing squad inside your roadmap. Best for long builds.
Named seniors join your team. Best when you own delivery.
Architecture and review only. Best before a licence filing.
Not sure which fits? Most teams start with discovery. It is short, and it ends with a written architecture you own either way. Read the compliance approach or the delivery examples first if that helps.
Bring the licence you hold and the date you need. We will come back with a scope, a team shape and a risk list. No demo required.
