Software built to last,by a partner who stays.
Experus designs, builds and runs the custom software, SaaS products and cloud infrastructure your organisation depends on every day. Senior engineering from the first conversation, and the same people still there long after go-live.
What Experus delivers
Five focused services, one point of accountability. Each ends with something you can point to: a release, a running platform, a written plan.
Custom Software
Business applications designed around how your organisation works, taken from idea to production and kept moving.
SaaS Development
Multi-tenant cloud products built to be sold, scaled and operated, from first version to hardened platform.
DevOps as a Service
Experus builds, automates and watches the infrastructure behind your software, so your cloud stops being a distraction.
Architecture & Technical Consulting
A senior second opinion before an expensive decision, or a clear diagnosis when a system is already hurting.
Legacy Modernisation
Bring an ageing Java system up to date without a big-bang rewrite, while it keeps serving the business.
How Experus works with you
Four stages, senior engineers throughout, no hand-off to a junior. These are the rules, and you are welcome to hold Experus to them.
Understand
Your business first, your tech stack second. You receive a written scope before any code is written.
Shape
A written design and an estimate that states its assumptions. Argue with the drawing before it becomes expensive.
Build
Working software in short increments, tests on every commit, progress you see in your own environment, not a slide deck.
Run and evolve
Production is the definition of done. After go-live Experus stays, for support, security updates and the next iteration.
Choose how Experus fits in
Every organisation needs something different from a technical partner. These are the three shapes Experus offers; a relationship can start with one and grow into another.
Project delivery
A defined scope, built end to end and handed over in a state your team can own. Best for a new product, platform or major feature with a clear outcome.
Fixed scope, milestone-based, with a documented handover.
Retained partnership
A monthly agreement covering operations, support and continuous improvement. Best when your software is core to the business and has to keep moving.
Monthly, with a response window agreed in the contract and a standing improvement backlog.
Embedded senior engineer
Experus joins your existing team for a fixed period to lead an architecture change, raise engineering standards or unblock a critical stream of work, inside your tools and your release cadence.
Time-boxed, part- or full-time, working in your repositories and your rituals.
A Belgian software company built around senior engineering
Experus BV is a Belgian software company that gives organisations something surprisingly hard to find: direct access to senior engineers, with no agency layers between you and the people doing the work. It goes deep on the JVM, Spring and PostgreSQL rather than spreading across every stack, which is what lets it give you a straight answer quickly. Everything it builds is yours to keep: code in your repositories, infrastructure in your accounts, documentation in plain language.
Start with a conversation, not a proposal
One message, read by the engineer who would do the work. No sales queue, no obligation, and a clear answer when Experus is not the right fit.
