Customsoftwaredevelopment
Built and run by the same engineers
Off-the-shelf software forces your process into a shape somebody else thought up. Custom software does the opposite: it follows the way you work. We build it, and after that we keep it running — because that is where most of the bill sits.
Thebillisnotinthebuilding
You pay for building once. You pay for running it every single year: security updates, new requirements, integrations that change. That is the big line item.
We build so that line item stays small — tests that run automatically, monitoring that shows a failure before you report it, and releases small enough to roll back. That does not make building more expensive. It makes the years after it cheaper.
Secure,fastandaffordable—andhow
AI writes code, tests and documentation faster than we can by hand. That saves weeks on the work nobody enjoys.
What AI does not do is decide. Every line passes a senior engineer before it goes live. That is what keeps it secure, makes it faster, and costs you less — both in the build and in the maintenance after it.
Whencustomisthecheapestoption
Custom is not always the answer. These four signals say that this time it is.
-
Your process is your edge. What you do differently from the rest is not something you want to trade for a standard package.
-
You pay for licences you barely use. Many features, little that fits.
-
You keep it alive with exports and glue. Manual work every month that nobody wants to do.
-
You want to own it. The data, the code and the pace.
Whatwebuildandrunourselves
The best reference for custom software is custom software running in production. We built these four ourselves, and we keep them up ourselves.
-
Keana — planning software for city distribution.
-
CyberCloud CallController — making phone conversations searchable.
-
Agile Analytics — measures where software delivery gets stuck.
-
Zenthropic — AI phone agents that answer 24/7.

Frequently asked questions about custom software
What does custom software development cost?
It depends on scope and complexity, and you only know seriously after a first conversation. What we can say up front: we work in short cycles, so you see something working within weeks and can steer before the money runs out. Count on maintenance being a recurring line item afterwards — one we deliberately keep low.
Do you only build it, or do you keep it running too?
+
Both, and that is the point of this page. The software we build we also keep up: updates, monitoring, new requirements. At Keana we are even the entire engineering team for a client’s product.
Do you use AI to build our software?
+
Yes, where it helps. AI speeds up code, tests and documentation. Every line passes a senior engineer before it goes live, and the accountability sits with us — not with a model.
Who owns the software and the source code?
+
You do. The code is yours, your data lives in your EU cloud, and on exit you get everything. No lock-in.
How long before we can use something?
+
Weeks, not years, for a first working version. We start small with the part that pays off most, put that into production, and build out from there.
We already have software that is outdated. Can you modernise it?
+
Yes. We build the new version alongside the old and migrate step by step, without a big bang. How that works, and when it turns out cheaper than expected, is on our legacy software modernization page.
