Blackstone Apps

Blackstone Apps is a South African custom software and app development company built by two qualified Systems Architects with real enterprise consulting backgrounds.

We build custom web and mobile applications for businesses that need software designed around how they actually operate, not off-the-shelf tools they have to work around. We also specialise in Sage integrations, connecting businesses' existing Sage platform to custom applications, internal tools, and third party systems so their data flows where it needs to without manual capturing or workarounds.

Our work sits across two types of clients. Larger businesses with complex operational needs that require a purpose-built solution. And smaller businesses that want to stay competitive and not fall behind because custom software felt out of reach.

Before starting Blackstone Apps, both founders consulted at Sappi Global as SAP consultants. That background means we come at every project by first understanding exactly what the business needs, then building the right solution around that, not the other way around.

We are based in Johannesburg, South Africa and work with clients nationally.
