Most companies in our market do one or the other. We do both, on purpose — and each one makes the other better.
We build and launch our own AI products. They are how we prove, in public, what our architecture does at scale — and they are where our engineering compounds instead of ending with a project.
We design and build custom enterprise software and AI systems for clients. It is how you buy that same capability today, applied to your problem, with our senior people on it.
Four offerings. Each one ends in something that runs in production.
From feasibility to a product in the market. Proof of concept, MVP, full-cycle build, and the technical leadership to keep it moving. You get a product, not a pilot.
Web and mobile applications, and the backend systems that hold them up. Built to survive real traffic, real data and a real audit.
Architecture decisions you can defend to a board. Technology selection, scalable architecture, and an honest read on what AI will and will not do for your business.
Your policy documents and training material, turned into localized video modules in 20+ languages — built into your systems and governed by your data policy.
The AI Validation Sprint is a fixed-scope engagement run by our Head of AI and a technical architect. In fourteen days we map your workflows, assess whether your data is actually ready, and hand you a working prototype — with the specification and the budget to build it properly.
From €7,500 — fixed scope, fixed price.
Delivered by Appex for clients in telecommunications, retail, education and culture. Where a project was delivered together with a partner, we say so.
Appex is 20+ engineers, four out of five of them senior. On a Sprint you meet the Head of AI and a Technical Architect — not an account manager who relays your questions to someone else.
Book an AI Validation Sprint — or just send us the problem, and we'll tell you honestly whether we're the right team for it.
