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.
Our own product, in development

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.
