UCT student startup Tennsa is building software for South Africa’s overlooked small businesses

Tennsa, a software startup founded by University of Cape Town student Rivar Maharaj, is building an operating layer for South African wholesalers, retailers and other smaller businesses that have outgrown spreadsheets but still rely on fragmented or ageing systems.

The company’s first product, Tennsa OS, connects existing accounting, stock and payment systems so operators can see business information in one place. That makes it a useful South African test of whether modern business software can reach firms that mainstream cloud platforms often miss.

Built around systems already in use

UCT says Maharaj founded Tennsa in late 2025 while studying computer science and applied statistics. Rather than asking customers to replace every system they already use, Tennsa OS is designed to connect those systems and surface operational information across them.

That design choice matters in a market where many township and small-town businesses sit in an awkward middle ground: too complex to manage on a single spreadsheet, but too small to maintain dedicated data teams or expensive enterprise software. Paper ledgers, legacy servers and software with little or no internet-facing interface are still common.

The startup says it learns how each customer actually works before building around those processes. Hands-on discovery can win early trust. The harder question is whether that model can scale without turning every deployment into a bespoke software project that eats margin.

Pre-seed money, open commercial questions

In July, Tennsa closed a pre-seed round with Oakvale Invest. UCT says Oakvale took a minority stake and a board seat, and that the deal was the investor’s first on the African continent. The amount was not disclosed in the university’s report.

Tennsa has used the capital to expand engineering capacity and recruit from UCT. For a young company, that buys product depth. It does not yet answer customer count, recurring revenue, deployment cost or retention — the numbers that separate a campus story from an operating business.

South Africa’s software market is crowded at the top end, where large companies can buy mature ERP, cloud accounting and analytics products. Tennsa is aiming lower down the stack. That is the interesting part of the pitch. Integration without a costly rip-and-replace could close a real digitisation gap if the company can prove the work is repeatable.

The overlooked middle of SA retail tech

Point-of-sale gadgets and basic accounting apps are easy to find. What is harder is a coherent view across stock movements, supplier payments and day-end cash when those tools do not talk to each other. That fragmentation is where informal and semi-formal wholesalers lose time and money.

Tennsa’s bet is that an integration layer beats another standalone dashboard. If that holds, the company is selling relief from reconciliation work, not another login. If it does not, customers will treat Tennsa OS as one more screen to ignore when the shop gets busy.

What is still unresolved

The company has not yet published enough operating data to show how the model travels across thousands of very different businesses. Pre-seed backing and a UCT origin story open doors. They do not prove that overlooked retailers will pay, stay, and refer the next shop down the road.

If Tennsa can keep connecting stock, payments and accounts without forcing full system replacements, it is aiming at a problem South African small business actually has. Scale, unit economics and retention will decide whether that remains a student-founder spotlight — or becomes infrastructure.
