What we build when we are the client

Our own products are developed to the same standard we apply to client work — and they keep us honest: we operate what we design. KEEL, our first custom build, is delivered and in daily use.

Everything on board. In view.
KEELDelivered · custom buildBuilt for one client, built like a product: a shared register for physical assets and the documents behind them, with Finn — an AI assistant that answers from the client’s own data and works without the internet. Delivered and in daily use.See KEEL

How we work

Four things you can hold us to

  1. 01

    Scope before code

    Every engagement starts with a written scope, success criteria and a price you can budget. We would rather lose a project than start one on a vague brief.

  2. 02

    Your code, your accounts

    Source code, infrastructure and documentation live in repositories and cloud accounts owned by your company from day one.

  3. 03

    Security is part of delivery

    Content-Security-Policy, CSRF protection, input validation and least-privilege access are in the default definition of done — not a paid extra.

  4. 04

    Built to be handed over

    Architecture documents, runbooks and readable code mean you are never locked in to us to keep the lights on.
