You know what your business should look like online. We make sure it gets there — with clean code, honest communication, and a site that works as hard as you do.
Whether you're starting fresh, keeping an existing site healthy, or automating the busywork — we scope it clearly and build it to last.
Bespoke, fast-loading websites designed around your business and built to convert — not a recycled template.
Hosting, updates, security and small changes handled monthly — so your site stays fast, safe and current.
Bookings, forms, CRMs and integrations that remove manual work and connect the tools you already use.
No jargon, no disappearing acts. You'll always know what's happening and what comes next.
We talk through your goals, your customers and what success actually looks like for you.
You get a clear scope and a fixed price up front — no hourly surprises later on.
We design, build and review in stages, keeping you in the loop at every milestone.
We launch with care and stick around — with optional care plans to keep things running.
Horizon Development is a boutique digital agency based in Johannesburg. You work directly with Joshua Harris — the person who builds your site, not a junior handed a brief. Founded because too many small businesses were being oversold by large agencies and underserved by cheap freelancers.
