Thesis
We govern, diagnose, and recover commercial loss others never see.
Most service businesses lose more revenue between channels than they ever capture on the website. The gap between an enquiry arriving and a confirmed appointment is where commercial value evaporates — silently, across SMS, WhatsApp, Instagram, missed calls and forms.
That gap is not a marketing problem. It is an infrastructure problem. We build the systems that close it with provenance — every recovered booking traceable back to the message that started it.
We apply the same governing discipline to AI features: behavioural invariants, honest failure diagnosis, and repair paths your coding agent can act on — without faking confidence the evidence does not support.
Portfolio
Three products. One standard of evidence.

Operating principles
How we govern what we build.
- 01
Attribution is a primitive
Every recovered conversation, every booking, every pound of revenue ties back to the message that started it. No black boxes. No unattributed wins.
- 02
Vertical depth before horizontal breadth
We go deep on one industry vertical at a time. Dental first. Aesthetics, optometry and physio thereafter — never all at once.
- 03
Operators, not eyeballs
Our customers are practice owners and operations leads. We build for the people accountable for the number at the end of the quarter.
- 04
Quiet UI, loud signal
The interface should disappear. The commercial signal — what to do next, and what it will be worth — should not.
- 05
Honest certainty
Whether diagnosing revenue leakage or AI regression, we refuse to fake precision. Low confidence means investigate first — not blind fixes.
- 06
UK-first by design
Built around UK appointment economics, GDPR posture and operator workflows — not retrofitted from an American template.

Questions operators and builders ask us.
What is Reply Intelligence Group?
Reply Intelligence Group Ltd is a UK company that builds commercial infrastructure for appointment-based businesses and AI reliability tooling for product teams. The flagship product is ReplyOS, a revenue intelligence platform for healthcare practices. DriftGuard is an open-source tool for regression locks and honest failure diagnosis in AI/LLM features.
What is ReplyOS and who is it for?
ReplyOS is a UK-first vertical SaaS revenue infrastructure platform for dental practices and other appointment-based healthcare businesses. It captures enquiries across SMS, WhatsApp, social channels, email and web forms; assists with AI-guided responses; converts conversations into bookings; and attributes revenue back to the originating message. It is built for practice owners and operations leads, not generic marketing teams.
What is DriftGuard and how is it different from AI eval tools?
DriftGuard is a CI-first tool for defining behavioural invariants (locks) on AI features. Unlike observability tools that primarily detect and score regressions, DriftGuard focuses on diagnosis and repair: it ranks likely causes, applies an honesty cap to confidence based on available evidence, and emits mode-gated repair prompts for coding agents. It refuses to suggest blind fixes when evidence is insufficient.
How does DriftGuard's confidence model work?
DriftGuard uses a three-tier honesty cap. With signature or pattern evidence only, confidence is capped at 0.40 and the system enters investigate_first mode without ranked files. Adding an execution trace raises the cap to 0.69. Git diff or bisected commit evidence removes the cap, allowing high confidence and suggest_patch mode when causal evidence links the failure to a specific change.
What is ReplyBench and how does it relate to ReplyOS?
ReplyBench is a live enquiry leakage diagnostic at replybench.co.uk. It scores six dimensions — enquiry speed, CTA clarity, follow-up readiness, competitor positioning, trust signals, and revenue tracking — into a single ReplyBench Score with an indicative revenue-at-risk estimate. The free Snapshot is instant; a Full Audit (£199) adds human review and a 30-day plan. ReplyBench diagnoses where leakage occurs; ReplyOS provides the infrastructure to fix enquiry handling, follow-up and attribution at scale.
Where is Reply Intelligence Group based?
Reply Intelligence Group Ltd is registered in England and Wales. Products are built UK-first around GDPR posture, UK appointment economics and operator workflows.
