Build
Designed and written by a named engineer who answers for it. Reviewed, tested and typed end to end before anything ships.
Critical Systems Engineering · Est MMXX
The systems institutions cannot afford to lose.
We engineer and run systems across finance, health, property and recruitment. When they fail, money stops moving, patients wait and records stop being trusted.

Where we work
One standard. Four domains.
Finance, health, property and recruitment carry different risks: a payment that will not reconcile, an outage mid-treatment, a record found wrong years later, a candidate’s data exposed. One standard holds across all four.

change-control requirement
We commit to 99.999%. We have not yet needed the margin. Service targets are written into every managed engagement, and after launch the systems, controls and people behind them remain our responsibility.
Method
Build. Operate. Answer.
The people who build your platform are the people who run it. Whatever the question, whatever the hour, you reach the engineer who knows the system.
02
Operate
Instrumented and measured against clear service targets, patched and kept current as threats move. When something slips, the person who built it is on call.
03
Answer
A direct line, and a traceable history behind every change. Reviewed and documented as we build, in plain language a person can follow.
Private AI
The model stays where the data belongs.
Dedicated hardware, controlled deployment and a person accountable for every accepted output. We choose the model, data boundary and infrastructure as one system.
Security
Built like the things it protects.
The controls these standards demand are built in from the first commit. Cyber Essentials certified; UK GDPR throughout; ISO 27001 certification in progress.
- Clearance
- Engineers vetted to the standards of the institutions we serve.
- Isolation
- Isolated to the account level: infrastructure, keys, credentials and tooling, never shared across clients.
- Provenance
- Every dependency vendored, verified and pinned, so nothing breaks at 3am.
“We keep critical software running for years, in places where lives, liberty and livelihoods depend on it. We answer for every system we build.”
