What we have built

10 projects so far. Most are for people who work with horses, because that is the world we know best, but the same approach has served a game reserve, a scientific instrument maker and a children's author.

StableSync

In development
StableSync dashboard for a demo yard, showing horses, today's bookings, pending requests and overdue invoices.

StableSync runs a livery yard from one place: horse profiles with feed, rugging and health records, arena bookings that can't clash, staff rotas and tasks, care reminders and invoicing.

Each yard gets its own branded space and its own separate database. Vets and farriers get in through a time-limited link, with no account to set up. It runs in English, French and Spanish, and versions for polo clubs and equine vet practices are in development.

TeamMate

Live, iOS in beta
TeamMate's Today screen on a phone, with a readiness score, the latest ride and the next race.

Human coaches write the training plans. AI personalises and explains them. Fixed safety rules, written in code, decide what an athlete is allowed to be shown.

Athletes can move, swap and log sessions, then see each one broken down afterwards: route map, pace, heart rate and power zones, swim lengths and personal records. It takes in data from Garmin, Oura, WHOOP and Apple Health.

Solio Reserve Companion

Live
The Solio Reserve Companion welcome screen on a phone, confirming the map is saved for offline use.

Solio is a rhino sanctuary in Laikipia. Guests drive themselves, and there is little signal. We took the reserve's illustrated map and matched it to real coordinates, so the dot showing where you are sits on the right drawn track, gate or dam.

Once loaded, the app works with no connection at all. By design it never holds or shows where any animal is, so a guest's phone can't become a map for poachers.

Practice app for an equine physiotherapist

In use

Treatment records with drawing on a horse body map, session photos, signed consent forms and vet referral notes. Reports and invoices come out as branded PDFs, ready to send from the yard.

Invoicing handles two currencies, billing a whole team with one invoice per player, part-payments and statements. Everything is stored on the iPad and backed up daily, so it works with no signal.

Oxford Microbeams

Live
The Oxford Microbeams home page.

Oxford Microbeams makes equipment for ion beam analysis, used by universities and national labs. We rebuilt the website with a product catalogue, kept every old link working with redirects, and made it usable by keyboard and screen reader.

We also moved the website, email and domain records to a new provider without losing mail, and rebuilt the way software updates are published to customers' instruments.

Matt Davies, children's author

Live
The Matt Davies author site home page, with two picture book covers.

Matt writes rhyming picture books for two to six year olds and posts out signed copies himself. We rebuilt his site as a storybook-styled shop: signed and unsigned copies, bundles, free activity sheets to download, reviews and a blog.

Every old address redirects to its new page, so nothing was lost in search. We also delivered a six-week marketing kit of posts, emails and graphics.

Hurst Grange Equestrian

Live
The Hurst Grange Equestrian home page, with the yard and arena behind the logo.

The app gives owner, manager, staff and livery clients their own view of the yard: horse records, indoor and outdoor arena bookings, staff rotas, and invoices with a bill each client can check.

Alongside it we built the yard's public website, covering livery, facility hire, lessons and clinics.

Catalogue app for a motorbike collection

In use

A spreadsheet stops working at 300 bikes with photos, insurance dates and stories. This app holds each bike's details, a photo gallery, its service and restoration log with costs, and the memories that go with it.

It warns when insurance or a roadworthiness test is due, shares a bike as a PDF, and backs the whole collection up to a single file. Nothing leaves the phone.

Route planner for mobile vets

It weighs travel time, fair workloads, which vet already knows which client, and arrival windows, then re-plans when an emergency call comes in. An AI assistant helps sort incoming requests by urgency.
