ABC Tech House · Kigali
ABC Tech House is an iOS and Android studio. We make our own apps for mobile money, electricity and EV charging, and we build mobile products for startups and teams.
What we do
We keep the offer intentionally narrow: build the product and guide the technical decisions.
iOS and Android apps built in Swift and Kotlin, with product architecture, API integration, release support, and the care needed for long-term maintenance.
Technical guidance before the expensive mistakes happen. We help scope the right first version, choose the right stack, and turn loose ideas into buildable product plans.
Selected work
These are our own products, made for everyday life in Rwanda: paying with mobile money, buying electricity, and charging an electric car.
Mobile money
Send money, pay merchants and buy airtime in Rwanda without working through long USSD menus. It also keeps a timeline of what you sent and received.

How we work
Good software is not just code volume. It is prioritization, taste, technical judgment, and honest communication when the project hits the messy middle.
01
We map the user, business goal, launch constraints, and the smallest version worth building.
02
We turn the idea into flows, architecture, milestones, and a build plan that can survive real tradeoffs.
03
We ship native mobile and supporting API work with testing, store preparation, and post-launch iteration.
