For banks, EMIs, payment institutions, neobanks and regulated fintechs
Core banking, payment rails, SEPA Instant, wallets, embedded finance, crypto banking, clearing and digital-asset infrastructure for banks, payment companies and regulated fintechs, with ISO 20022 built in.
8 years in regulated finance. We build the core where you need one, and integrate into the one you already run where you don't.
What we own
What we integrate with
One team owns what joins them.
Expertise
We design, build, and maintain secure, reliable software that scales with your business.
Core banking, SEPA Instant, card program integrations, payouts, reconciliation and ISO 20022 messaging.
Learn moreAgents that work across the systems you already run, inside limits you set. Reading and writing stay separate, and every change goes through approval and leaves a record.
Learn moreOne path to every environment. Cloud platforms, GitOps delivery, private networks, secure SDLC and CI/CD — the desired state of each one lives in a repository.
Learn moreWe integrate transaction monitoring, KYC/KYB orchestration and audit trails with established providers and build them for regulatory scrutiny.
Learn moreCrypto, when you're ready. Embedded crypto banking for banks, multi-chain wallets, exchanges and on-chain compliance - the same regulated-grade rigor, applied to digital assets.

Systems that go into a live core without taking it down.
1 of 5: Transfers, FX and Clearing
Systems in production, written up as far as an NDA allows.
We use AI across discovery, development, and testing, with human review and approval matched to the task.
Claude Certified by
01
We use AI to turn requirements and designs into working prototypes, so teams can test assumptions before committing to a full build.
02
AI supports test generation and code review as changes are made. Engineers validate the results and resolve issues before release.
03
We're developing an agent for the daily close, with routine tasks automated, exceptions escalated, and human approval where required.
Adding security, an audit trail, or a second vendor later means rebuilding what already works.
Fiat and on-chain sit with the same engineers. A settlement and a wallet are one integration, not two vendors.
Security, compliance, and audit are built in from the first commit, well before a regulator asks.
The tooling drafts. The review after it is no shorter than it was before.
Architects and engineers with hard-won experience in finance, each owning a domain end to end.
