About
Data and technology. Built for Uganda.
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
Uganda's businesses deserve better systems
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.
Why we started
Built here, for how things actually work here
Imported software assumes a fast connection, a card payment and a support desk in another timezone. We build for the conditions our clients are actually in, because we work in them too.
- Offline-first where the signal drops
- Mobile money as a first-class payment method
- Fast on the data bundles people actually buy
- Support in the same timezone, in the same city
What we do
Four areas. One company.
We are not just a software studio. We cover the full technology stack a growing organisation needs.
Software is only part of it. We also supply, install and configure the hardware and networking it runs on, so one team is accountable for the whole system rather than passing the fault between a software vendor and an IT contractor.
Custom Software
School management, pharmacy, retail POS, SACCO and microfinance, clinic management and mobile apps, built to the exact processes of each client, not adapted from a generic template.
ICT & Electronics
Computers, networking equipment, printers, accessories and smart devices. Supply, installation and configuration for homes, offices and factories.
Computer Training
Practical, job-ready computer literacy from basic skills to business software and programming. Delivered in person, and to your staff as part of a system rollout.
Technical Support
Hosting, monitoring, backups and ongoing changes. Systems stay live and up to date. We remain on hand well past the handover date.
