Custom software development

Custom software, built to run, not just to demo.

Have an idea for a tool, a platform or a product? We scope it, build it as real production software, and keep it running on European infrastructure. You talk to the people writing the code.

The problem

Most "custom software" never makes it into daily use.

It demos well, then stalls, half-finished, undocumented, or handed over in a state nobody internally can maintain. Agencies disappear after launch, and the hosting becomes someone else's problem at the worst possible moment.

We work the opposite way. We build software the same way we build our own products: complete, documented, and hosted by the people who built it, so it's still working a year later.

What we build

From a single tool to a full platform.

Multi-tenant SaaS

Products with their own users, billing and per-customer data, the architecture behind BonusFlow and BonusBooks, applied to your idea.

Internal tools & dashboards

Replace the spreadsheet and the manual process with something that fits your workflow exactly.

Integrations & automation

Connect the systems you already use so data stops being copied by hand between them.

Client & customer portals

Secure, branded areas where your customers self-serve, requests, documents, updates.

APIs & connectors

Clean, documented APIs so your software talks to the tools around it.

AI features done sensibly

Summaries, extraction and drafting where they save real time, not bolted on for show.

How we work

Production-grade, hosted and looked after.

  • Scoped and priced up front. You know what gets built and what it costs before a line is written.
  • Built on a proven stack, the same modern tooling we run our own platforms on, secure and EU-hosted by default.
  • Delivered complete, no prototypes, no placeholders, and documentation you can actually hand to someone else.
  • Hosted and maintained. We keep it live, backed up and monitored, so it stays your asset rather than your liability.

Good to know

Common questions

Do you only build, or also host and maintain?
Both. We build the software and run it on European infrastructure, backed up, monitored and supported. You're never left holding code you can't keep running.
Will I own the software and the code?
Yes. It's your software. We can also arrange source-code escrow for larger builds so you're protected regardless of what happens to us.
How much does custom software cost?
It depends entirely on scope, which is exactly why we price it up front after a short call, no open-ended hourly surprises. Smaller tools start modestly; platforms are quoted against a clear spec.
Is my data kept in the EU?
Yes, everything runs on EU-hosted infrastructure, built GDPR-first, with data export and erasure available.

Let's talk

Got an idea you keep wishing existed?

Bring it to a short call. We'll tell you honestly whether to build it, what it takes, and how fast it can be live.
