AI shouldn't bethis hard to use.
The story
Single Source started as a Durban design and development studio. We were good at it. Then AI started shipping the commoditised work for free — landing pages, copy, basic apps — and the market shifted under our feet.
Instead of racing to the bottom, we leaned into what those tools can't do: understand a specific business problem, design a system to solve it, and deploy that system until it actually works in production.
Today Single Source is an AI Systems Integrator. We deploy AI against the operational, commercial, and technical problems that businesses across KZN, the SADC region, and the UK SME market actually face. We don't sell AI. We build the systems AI runs on, and we don't leave until the problem is solved.
Why we exist
Most businesses know they need AI. Few know where to start. The market is full of vendors selling tools, platforms, and dashboards. But nobody is sitting down with the operations lead and saying: “Show me the process that's costing you money. Let's fix it.”
That's the gap. Not more AI products. More AI applied to specific, real-world problems. That's what SSS does. We're the integrator between what AI can do and what your business actually needs.
Rainier Potgieter — Full-Stack AI Architect
Single Source is founded by Rainier Potgieter, who manages a portfolio of 27 active projects at the intersection of autonomous AI engineering, enterprise FinTech, and regional digitisation. His work is characterised by building the infrastructure that AI runs on — not just the applications on top.
Notable builds include Modular9, a visual multi-agent workflow builder; DataLineage, an AI platform automating Big 4 consulting work for BCBS 239 and IFRS 17 compliance; and BOQ-Web, a SaaS for construction cost management.
When we build your system, it's built by someone who understands how AI actually works at the infrastructure level — not just how to call an API.
What we bring
AI Workflows & Automation
Document pipelines, regulatory reporting, CRM and approval workflows. We replace manual process with systems that run themselves — measured in hours saved per week from day one.
Decision Support & Data
Custom decision-support built on your existing data. Not generic BI. Specific questions, specific answers — what to stock, where to cut, when to act.
AI Agent Systems
Autonomous multi-agent pipelines and orchestration. Continuous workflows that run without supervision — research, monitoring, intelligence gathering.
AI-Native Product Builds
MVPs, client portals, internal SaaS. Production-grade architecture from week one, full handover at the end. Your team owns the code, infrastructure, and knowledge.
FinTech & Compliance
Financial data lineage, BCBS 239 / IFRS 17 automation, audit trail generation, regulatory reporting. Built for accounting firms, financial services, banks, and insurers.
