Quantyx builds iOS apps and AI systems. South African. Published on the App Store. Built to last.
Building at the edge of what one person can ship.
Vuyo Nkadimeng is 26. He directs Quantyx — an AI-native iOS app studio — and Africortex, an IT services business, in parallel with a senior corporate software-leadership role. Running three demanding disciplines at once is not a claim. Five live apps on the App Store are the receipt.
Quantyx does not have a product team of thirty. It has a structured AI agent organisation — each function operating on a daily cadence — and one human who sets the direction, writes the code, and ships the builds. The operational model is the point: if it works here, it works for your company too.
"The agent org is not a pitch deck concept. It runs daily digests, weekly strategy rounds, and completion reports."
The technical stack: Swift and SwiftUI for native Apple apps, Node.js and Python for AI systems, AWS and GCP for infrastructure. South African by choice — building for the local professional, in rand, in SA context, with global distribution.
Five apps live. More in build.
Built in Swift. Published on the App Store. South African by origin, global by distribution.
