// About Us
We're a product-focused software engineering studio
KSE Labs (Pty) Ltd is a software engineering company based in Johannesburg, South Africa. We don't just take mobile application and web platform briefs and execute them, we own builds end to end: a ride-hailing app's real-time backend, a privacy-first AI platform, and the custom circuit boards and proprietary communication protocol behind an access control system we engineered in-house, hardware included.
That range is deliberate. Whether you need an iOS app developer, an Android app developer, or a full-service software development company in South Africa that can take a build from idea to custom hardware, KSE Labs has shipped it before. Multiple apps live on the Apple App Store and Google Play Store, across industries from beauty to transportation to food tech, all built and still maintained by the same team.

// Testimonials
What Our Clients Say
★★★★★
"We went through two other devs before KSE Labs and both ghosted us mid-build. These guys actually shipped — booking, payments and staff scheduling all working before our salon's first month-end. Took longer than the original quote because we kept adding features, but they were upfront about that instead of just padding the invoice."
★★★★★
"We were replacing physical access cards across the whole estate, and I was bracing for weeks of residents struggling with a new system. The KeeLess install team handled onboarding directly, and revoking a lost credential now takes minutes instead of waiting for someone to physically hand back a card. Took a bit of adjusting for our older residents, but support sorted out every issue we raised."
★★★★★
"Building a ride-hailing app with live tracking and driver payouts was way more involved than we expected, and there were a couple of rough weeks getting the matching logic right. KSE Labs stuck with it, explained the trade-offs in plain language, and Ubii has been running reliably since launch."
