Probably right
isn’t good enough

From onboarding to remediation, banks run on judgements that regulators will inspect. Rainbird delivers them consistently, at machine speed, with the reasoning shown.

  • KYC, AML and sanctions decisions with full evidential trails
  • Complaints and redress decisioning against FCA expectations
  • Credit policy, payments and fraud referrals applied identically at any volume

A question about a decision made eighteen months ago is usually a records problem. With Rainbird it’s a lookup. Every outcome keeps its evidence tree: the rules that fired, the facts used, the certainty reached.


Underwriting and claims are judgement businesses. Rainbird captures that judgement and applies it precisely, so every insured, broker and regulator gets the same fair answer and the reasons for it.

  • Underwriting eligibility and referral decisions from your appetite and policy wordings
  • Claims triage, liability and recoveries decisions with complete transparency
  • Fraud identification at volumes human teams cannot reach

Fair value and consumer duty turn on whether similar cases were treated alike. Rainbird decides from one model, so consistency is built into the decision rather than checked in a sample after the fact.


Professional services firms sell institutional expertise. Rainbird digitises it once and applies it across every engagement, freeing experts for the judgement calls that genuinely need them.

  • R&D tax eligibility and benchmarking in seconds rather than hours
  • Sustainability audit and regulatory applicability decisions from a single governed model
  • Advisory methods turned into decision tools clients can use directly.

When a partner retires, the method tends to go with them. Encoding it in Rainbird makes it readable, versioned and reviewable by whoever comes next.


Clinical and regulatory decisions demand precision and traceability. Rainbird brings both to high-volume processes without removing human accountability.

  • Prior authorisation and eligibility decisions with clinical-grade audit trails
  • Provider enrolment and complex claims decisioning
  • Medical, Legal and Regulatory (MLR) review acceleration, as in Klick Guardrail™

An LLM shouldn’t be the thing that decides a clinical case. Rainbird reasons deterministically over your protocols and asks for what it needs when a case is thin on data. It hands back a decision with the reasoning attached, so the clinician keeps the call.
