A South African development team building software for SMEs, research labs, and product companies — from native mobile apps to three-tier business systems on Azure.

Trusted on projects for Automart and OutSurance.

What we build

Three things, done seriously.

Three-tier business systems

Custom UI, business logic, and data layers — built on C#, MSSQL, and Azure for stability and security at scale. The kind of system that replaces five spreadsheets, three email threads, and a WhatsApp group with one tool your team actually uses.

Mobile apps

Native and cross-platform. iOS and Android apps for businesses that need their product in customers’ pockets. Native where performance matters, cross-platform where speed-to-market wins. From wireframe to App Store launch.

Sales sites and conversion optimization

Websites built to convert, not just to look good. We helped build automart.co.za — one of South Africa’s largest auto marketplaces — and we know what moves the needle: page speed, structured user journeys, tracking, and iterative testing.

Personal insurance lines

Assisted in developing personal insurance lines for one of South Africa's largest insurers. High-stakes systems where reliability and correctness aren't optional.

Process

How we work.

Two engagement models. Fixed-price when scope is clear and you want a predictable number. Retainer or hourly when the work is exploratory, ongoing, or evolving. We’ll tell you which fits in the first conversation.

  1. 01

    Discovery

    Understand the real problem before writing code.

  2. 02

    Design

    Architecture, interface, and a clear plan you can sign off on.

  3. 03

    Build

    Working increments you can see, not a black box for three months.

  4. 04

    Handover or ongoing support

    Your call.

Stack

Built on what we trust.

We work in the Microsoft ecosystem because it’s stable, well-supported, and a safe long-term bet for businesses that need their software to still be running in five years.

About

About.

We’re a small core team based in South Africa, working with a trusted network of specialists we bring in by project. Small enough that you talk to the people writing the code. Experienced enough to have shipped systems used by hundreds of thousands of South Africans.
