Architecture from people who have run it in production
We design payment platforms end to end, from switching and issuing to tokenization, keys and fraud, and we review existing designs before they become expensive problems.

Sound familiar?
These are the situations where this service makes the biggest difference.
You're building a switch, issuing or acquiring platform
Vendors and teams need specifications they can build against
A design needs an independent review before sign-off
Legacy and new platforms have to run side by side
How we help
Target architecture
End-to-end architecture for availability, security, scale and certification, documented so it can be governed.
Solution design and specifications
Message specifications, interfaces and transaction flows, written to the level vendors can build and test against.
Independent architecture review
A structured review of an existing or proposed design, with prioritized, practical recommendations.
Migration and coexistence
Transition architectures that let old and new platforms run together until cutover is safe.
Clear deliverables, agreed up front
Every engagement starts with a written proposal covering scope, team, timeline and deliverables. You always know what you're getting, and your team keeps everything we produce.
