About DigiBannister
We're a Johannesburg-based web development agency on a mission to build websites that actually work for South African businesses — fast, mobile-first, and designed to convert.
Duncan Bannister
Founder & Lead Developer
A passionate web developer based in Johannesburg who saw the gap between what SA businesses needed and what agencies were delivering. With experience in mobile-first development, e-commerce, and WhatsApp integration, Duncan founded DigiBannister to build websites that actually work for South African conditions — slow connections, mobile-first users, and local payment preferences.

Our Mission
Mobile-First, Always
95% of South African internet users browse on mobile. We design for them first, not as an afterthought.
Performance is Non-Negotiable
A 3-second delay loses 53% of visitors. We build sites that load in under 2 seconds, even on 3G.
Real Results, Not Just Code
Beautiful code means nothing if it doesn't convert visitors into customers. Every decision we make is driven by business outcomes.
