Managed Service 20 / 23
Headless CMS
Content in one place, published everywhere — at static-site speed.
A headless CMS separates where your content lives from where it appears. We design the content model, build the front end, migrate what you already have, and manage the whole thing — so your team edits in a clean interface while pages serve from the edge in milliseconds.
What Headless CMS delivers
Modelled, not improvised
Content types, relationships and reuse designed up front — so the same content serves the site, the app and the feed without being duplicated.
Migrated with the history intact
Existing pages, media, URLs and redirects moved across, so rankings and inbound links survive the move.
Fast because it is static
Pages built at publish time and served from Cloudflare's edge — no database sitting between your visitor and the page.
Editors keep control
Previews, scheduled publishing and role-based permissions, so marketing ships without a developer in the loop.
Representative stack
Generative, RAG and Agentic
Three different things \u2014 most businesses need more than one.
A content system with no front end of its own — it stores and serves content through an API, and the website is built separately.
When you need it: When the same content has to appear on more than one surface, or you want to redesign the site without touching the content.
Defining the shape of your content — the types, the fields and how they relate — before anything is built.
When you need it: It is the decision that determines whether the next five years of publishing is easy or painful. It is also the one most often skipped.
Choosing a specialist tool for each job — content, search, commerce, identity — and joining them, rather than accepting one vendor's version of everything.
When you need it: When a single platform is holding back one part of the business and you cannot replace just that part.

Why this matters
Functional value, value-stream value — and why it can't be ignored.
Designs the content model, builds the front end, migrates existing content and runs a headless CMS end to end — Sanity, Storyblok, Contentful, Strapi or Payload, served through Astro on Cloudflare.
The publishing engine of the value stream: it decouples how fast your team can publish from what it costs to change the site, so content ships in minutes and every channel draws from one source.
A monolithic CMS ties your content to one template on one site. The moment you need a second brand, another language, an app or a partner feed, you are re-keying the same content by hand — and paying for a rebuild every time the design changes.
One data layer · measured & owned
Every service creates data — captured, measured, owned.
Headless CMS doesn’t just run — it generates signal. We land that data in one warehouse and turn it into live KPIs tied to a named owner, so performance is attributable and acted on, never trapped inside a single tool.
Data warehouse
KPIs, dashboards & apps
Platform-agnostic — we connect what you already use and add a warehouse only where it earns its place.
How we select technology
We choose technology last — for the outcomes it has to earn.
Never tech for its own sake. A tool joins the stack only where it measurably protects value, cuts cost or unlocks speed — fit to a designed system, owned where it counts, and measurable from day one. How we select technology →
Speed
Modern, edge-served stacks are sub-second. Slow surfaces cost conversion and SEO every single day.
Cost
Cut licence, hosting and per-task SaaS fees — pay for capability, not lock-in or idle enterprise tiers.
Security
Flat, edge architecture with almost nothing left to attack — fewer moving parts, smaller surface.
Ownership & no lock-in
Composable and self-hosted where it counts — you own the system, not rent someone else’s.
Measurability
Clean data and KPIs baked in — you cannot improve, automate or apply AI to what you cannot measure.
Fit to process
The right tool for a designed system — selected against process readiness, so it amplifies, not adds friction.
How we deliver · DMAIC
Every Headless CMS engagement runs on DMAIC.
Define the goal and its value, measure the baseline, analyse the real constraint, improve with a proven build, then control the gains — so results are predictable, repeatable and defensible, not down to luck.
Agree the goal, value, budget & timescale up front.
Baseline the KPIs above — current state, not guesswork.
Diagnose the real constraint and the solution needed.
Build the chosen solution; prove the uplift.
Lock in the gains; monitor and sustain them.
