How We Work · Engagement Model
Every engagement
starts with a conversation.
Three delivery options — Project, Support and Managed service — depending on where the business is and what it needs. All begin with Discovery. All are outcome-led. All include a Financial Value Model before any significant investment.
Delivery options
Project
A defined-scope delivery targeting specific constraints — a build, a migration or an AI integration. Fixed scope, measurable ROI.
Support
Monthly support for what you already run — updates, security patches, uptime monitoring, fixes and a set number of improvement hours.
Managed service
We run it for you — a single service or the complete Growth & Control Engine, with a live Control Centre, continuous improvement and direct senior access.
How Every Engagement Starts
Five steps, measured throughout.
Discovery Session
A structured, no-commitment commercial conversation about value at stake.
Discovery & Blueprint
All 14 outputs — market sizing, value model, roadmap and business case.
Agree the Route
Agree the delivery option, scope, investment and measurable targets before delivery.
Deliver with Control
Implementation with governance, monitoring and adoption from day one.
Measure & Improve
Ongoing benefit tracking, monitoring and monthly senior reporting.
The DMAIC Method
Strategy before spend.
Every pound is mapped to a number, an owner and an outcome — so the engine compounds instead of leaking.
Agree the goal, value, budget & timescale up front.
Baseline current state — leads, CAC & pipeline.
Diagnose the issues and identify the solutions needed.
Build the chosen solution; prove the uplift.
Lock in the gains; monitor and sustain them.
Monitoring & Control Centre
Real-time visibility. No surprises.
Every managed engagement includes a live Control Centre — real-time visibility across revenue, pipeline, SLAs, automation, AI utilisation and customer signals. You always know what is at risk before it costs you.
Investment
Priced to the work — and to the value it creates.
No two engines are the same. Budgets start at £3,000 per month and are shaped by the work itself — anchored to a value model, not a quote.
Hold the line — reduce risk, eliminate leakage and protect what you have.
Lift conversion, retention, efficiency and margin across the whole engine.
Build new revenue, AI capability and scale — the compounding tier.

FAQ
Pricing & engagement — answered
How much does Sentry cost?
Managed services start from £3,000 a month and are priced as a percentage of your annual sales. The percentage rises with the service level you choose, Protect, Enhance or Create, and steps down above £8m turnover. Third-party tool costs for the services we manage are included up to a fair-use cap; paid advertising spend is excluded. We confirm every figure in your quote.
What are the delivery options?
Three, all starting with Discovery: Project (a defined-scope build with measurable ROI), Support (monthly support — updates, security patches, monitoring, fixes and improvement hours) and Managed service (we run it for you, with a live Control Centre and monthly reporting). Most services are available all three ways; Digital Ads is delivered as a managed service only.
Is the Discovery session really free?
Yes. The Discovery Session is free of charge and carries no obligation. You leave with your likely constraint named and a first estimate of what it may be worth, in a one-page written summary. We quantify the value at stake in a Financial Value Model before you commit. If the model does not support the work, we say so.
How is value measured?
Every engagement includes a Financial Value Model — value at stake quantified before investment, best/base/downside sensitivity on major recommendations, and realised benefit tracked against the model in a live Control Centre.
What methodology do you use?
We apply DMAIC to improve what exists and DMADV to design what's new, governed by a five-level operating maturity model — so results are predictable, repeatable and defensible.
