About
Open Sigma Data Solutions Limited was founded to close the gap between enterprise-grade technology and the organisations that need it most.
Why we exist
Too many organisations here are running on paper, on spreadsheets that no longer agree with each other, or on software imported wholesale from other contexts that never quite fits local workflows, local taxes, or local connectivity.
We build technology that is designed from the start for how businesses actually work in Uganda — offline-first where the signal drops, fast on mobile data where it doesn't, and built around the processes your people already follow.
What we do
We are not just a software studio. We cover the full technology stack a growing organisation needs.
ERP systems, school management, pharmacy, retail POS, clinic management and mobile apps — built to the exact processes of each client, not adapted from a generic template.
Computers, networking equipment, printers, accessories and smart devices. Supply, installation and configuration for homes, offices and factories.
Practical, job-ready computer literacy from basic skills to business software and programming. Delivered in-person and, soon, online through our eLearning platform.
Hosting, monitoring, backups and ongoing changes. Systems stay live and up to date — we remain on hand well past the handover date.
