Software for work that happens away from a desk.

Mettux is James Watt and Marine Metz: a software engineer and an equine vet. We build apps and websites for yards, clinics, clubs and small businesses, made to work on a phone in a field with no signal.

StableSync

Yard management for livery yards. Horses, bookings, staff rotas, care records and invoices in one app, in place of the spreadsheets and WhatsApp groups.

What we do

Apps that work offline

For phones and tablets used in yards, reserves and vans. Your records stay usable when the signal goes.

Websites and shops

Fast, readable sites for small businesses, including moves off platforms that cost more than they should.

AI with limits you set

AI that drafts, sorts and explains, with fixed rules in code deciding what it may do.

Who we are

James Watt

Product and engineering

James designs and builds the software, and keeps it running once it is in use.

Marine Metz

Equine vet and co-founder

Marine is a practising equine vet. She knows how a yard or clinic runs, and checks that what we build fits a real working day.
