We Engineer IoT.
From Sensor to Platform.

G-Matrix Systems was founded with a clear mission: build IoT devices that actually work in the field. Not just prototypes that demo well, but production-grade hardware that survives harsh African environments and runs for years on a single battery.

We saw that companies across Africa needed connected devices — for security, for logistics, for infrastructure monitoring — but the available options were either too expensive, too fragile, or too dependent on infrastructure that didn't exist in the regions where they were needed most.

So we built our own. The RAMAC product range now includes 13 IoT devices covering everything from perimeter vibration sensing to cold chain temperature monitoring. Every device is designed, tested, and manufactured in-house.
