Specialist software for specialist businesses.
Onyx Advance builds focused SaaS products for industries where generic tools fall short. Deep domain fit, serious engineering, no fluff.
One shipped. More in the workshop.
Every product is built for a specific industry — chosen for the depth of the problem, not the size of the market.
Lead capture that actually sells property.
A white-label proptech CRM for South African property developers — developments, leads, and sales pipelines, built for the way property teams actually sell.
The next product gets chosen the way ERF was — a real industry, a real workflow, a real gap.
We announce products when they're live, not before.
Fewer products.
Better fit.
Onyx Advance is founder-led and engineering-first. Every product is designed, built, and owned by the same small team that talks to the customers.
We look for industries that generic SaaS overlooks — places where domain nuance matters more than feature counts, and where a well-built tool can change how a business operates.
When we take something on, we ship it and keep shipping. No open-ended engagements. No ghost teams. The product either lives or it goes back in the workshop.
