What we have built, for clients and for ourselves.

Clients and products are described, not named. Where a client later agrees to be named and quoted, the case study will be updated.

Case study

A chartered accountancy practice

The situation

An established firm of chartered accountants had a website pointing at a host that no longer existed, DNS sitting on an orphaned zone nobody controlled, Microsoft 365 managed through a third-party reseller, and marketing material that disagreed with itself on basic facts. The principal wanted a credible online presence and to take control of the firm's own infrastructure.

What we did

  • Research and positioning: a competitor review, a structured client interview and a shift in positioning from "local practice" to a cloud-based firm serving clients across the UK at a lower cost base than practices absorbed into larger groups.
  • Copy: a full set of page copy for more than twenty pages, every unconfirmed fact flagged for the client rather than assumed, iterated with the client until approved.
  • Design and build: a fast, static site generated from source, with several design directions deployed side by side for the client to compare on a live preview rather than described in a document.
  • Imagery: AI-generated decorative imagery to avoid stock-licence risk, with real photography reserved for people and premises.
  • Infrastructure: a hosting account created in the client's own name with the principal as administrator; a full audit of live DNS and email records; a go-live plan that recreates the email records first and can be rolled back with a single nameserver change.
  • Compliance: a tracked-changes review of the firm's terms of business and engagement letters against the professional body's current guidance, so each change could be accepted or rejected individually.

The result

A preview site approved in wording by the client within a few weeks, ready to go live on infrastructure the firm owns, with a documented plan for email, DNS and Microsoft 365 that any future supplier could follow.


Products we have built

Web and mobile

A training planner for people who train alongside a sport

A web application that builds each week's training plan from what the user has logged and how ready they feel, with offline workout logging, wearable data from WHOOP and Withings, and a rule-based planning engine tested for identical results across two implementations. Built on Cloudflare's edge platform with per-user data isolation, automated release checks and a gated path from development to live. Currently in private use ahead of a public launch, with iPhone and Android apps planned.

Data and publishing

A results and reference service for an amateur sports league

Automated collection of results and line-ups from clubs' public posts, cross-checked so that every score has a source and conflicts are held for review rather than guessed. A static site of more than a thousand pages, rebuilt from structured data, with results cards, round summaries and short video highlights generated automatically and published on a schedule. Run by a small team of AI agents with distinct roles under human approval, with weekly performance tracked from the platforms' own analytics.

Why this matters to clients. We recommend the platforms, tooling and ways of working that we run our own products on. When we say a static site on Cloudflare costs almost nothing to run, or that an AI agent needs a human approving its output, it is because we have operated both.
