About Rex Solution
We build software — and we run it ourselves.
Rex Solution is a software company with teams in North Macedonia, Kosovo, Switzerland and Germany. We design, build and operate apps, platforms and AI — for our own products and for the companies we work with. What we build for you, we have already proven on ourselves.
Who we are
Engineers, designers and AI people — one team.
We are a team of developers, designers and AI engineers across four countries. We don't hand projects from one agency to the next: the same people plan, build, launch and support your product. And because we run products of our own, we know what it takes to keep software working long after launch.
What we did
From client projects to our own AI lab.
A few milestones from our journey so far.
Rex Solution is founded
We start building apps and websites for companies.
Client projects worldwide
Mobile apps, web platforms and designs for clients in many industries — taxi, food delivery, grocery shopping, health, travel, payments, jobs and sports.

Our own products
iLiria eSIM for travellers, the privacy-first apps iVeç and iSkano, and iLibri-Shqip rebuilt natively for iOS and Android.
A digital workplace for a hospitality company
An employee app with QR clock-in, schedules and leave requests — plus a private office cloud with e-mail, documents and meetings on the company's own servers.
Our own AI lab and AI products
NVIDIA DGX Spark and RTX 5090 in-house — where we train our own models and build our AI products: iLibri Studio turns books into audiobooks, AI Narrator reads them with voices we trained ourselves, and Otima AI is the private AI assistant and operating system for companies.
