Software, SaaS and AI services
Focused software, built in Belgium.
PurpleGreen builds software for organisations that deserve better tools than the generic ones. Each product does one job well, respects the people who use it, and runs in Europe.
Products
MartialBook
The all-in-one app for martial arts clubs: attendance, ranks and belts, kids' progress booklets, plans and payments, with apps for students and parents.
More products are on the way.
How we build
Security first
Built by a cyber security consultant. Security is part of the design, not a feature added later.
Hosted in Europe
Our services are hosted in Europe, under European privacy law.
Made for one job
No bloated suites. Each product is built around how its users actually work.
