Industries — where the stakes justify the rigour
Built for sectors where "usually right" isn't enough.
Finance, healthcare and the public sector share a property most AI vendors avoid: someone is accountable for every output. We design for that accountability from the first line of the specification.
Scenarios below are illustrative capability descriptions — not client case studies.
01 / Financial services
Model risk management, applied to language models.
Banks and insurers already know how to govern models — the discipline exists; generative systems simply arrived faster than the tooling. We bring LLM-based systems inside your existing model-risk framework rather than around it.
Committee-grade evidence, decision-grade trails.
- Model-risk alignment — documentation and validation artefacts structured to fit model inventory, validation and periodic-review processes.
- Decision traceability — every system output reconstructable: inputs, retrieved documents, model versions, guardrail verdicts, human sign-off.
- Explainability to non-engineers — outputs carry structured rationales a credit or risk committee can interrogate.
- Data boundaries — client and counterparty data handled under strict residency and retention constraints, disclosed sub-processors only.
A lender wants LLM assistance summarising document-heavy credit files. We would build the pipeline so that every summary cites its source passages, fails closed when documents are missing, logs every step to an audit record, and places final judgement with the credit officer — whose sign-off is part of the trail.
02 / Healthcare
Assistive by design. Accountable by construction.
In clinical settings the boundary is not negotiable: AI drafts, humans decide. We engineer systems that reduce administrative burden while keeping clinical accountability exactly where it belongs — with the clinician.
Special-category data, human sign-off, provable restraint.
- Hard scope limits — systems constrained to administrative and documentation support; diagnostic conclusions are architecturally out of bounds, not merely discouraged.
- Clinician sign-off checkpoints — no AI-drafted artefact enters the record without review by an identified professional.
- Special-category data handling — UK GDPR Article 9 obligations reflected in architecture: minimisation, residency, retention and access control designed in.
- Source-bound generation — drafts trace to the underlying encounter data; unsupported statements are flagged for review, never silently included.
A provider wants to reduce time clinicians spend writing discharge summaries. We would build a drafting pipeline that works only from the structured record, marks each claim with its source, routes each draft to the responsible clinician for correction and sign-off, and keeps the full draft-and-revision history as evidence.
03 / Public sector
Transparent enough to be questioned in public.
Public bodies operate under freedom-of-information duties, judicial review and algorithmic-transparency expectations. A system that cannot explain itself to a citizen has no business making decisions about one.
Auditability as a public duty, not a feature.
- Disclosure-ready records — audit trails and system documentation structured so transparency and FOI responses are an export, not an archaeology project.
- Transparency-standard alignment — system descriptions written to support algorithmic transparency reporting obligations from day one.
- Triage, not verdicts — AI assists ordering and preparing casework; determinations remain with accountable officers, recorded as such.
- Procurement-grade documentation — architecture, data flows and residual risks documented in plain language for governance boards and oversight bodies.
A department wants help triaging a high-volume correspondence backlog. We would build a classification and routing pipeline with published category definitions, per-item confidence and audit records, sampling-based quality review by staff, and a standing rule: anything ambiguous routes to a human queue.
04 / Common obligations
Different regulators. Same engineering answers.
| Obligation | Architectural answer | Where it lives |
|---|---|---|
| Every decision must be explainable | Source-bound outputs with structured rationales and citations | Verification layer |
| Every decision must be reconstructable | Decision-level audit log: inputs, versions, verdicts, sign-offs | Audit log |
| A human must be accountable | Named-owner escalation and sign-off checkpoints | Policy gate |
| Behaviour must not drift silently | Permanent evaluation suite re-run on sampled production traffic | Evaluation loop |
| Data must stay where it belongs | Residency-constrained deployment; disclosed sub-processors only | Deployment pattern |
