How a project runs, step by step

The same path in every industry. You always know the next step and who you are speaking to: the person who builds it.

  1. 01
    A 30-minute call

    We map the problem and decide together whether it is a product or a custom build. It is free.

    You get: A clear yes or no on fit

  2. 02
    A written scope

    Nothing is built before both sides agree, in writing, on what done means. Custom work is quoted in writing.

    You get: A scope document and a quote

  3. 03
    The build, with previews

    Decisions are made for the third year of operation, not for the demo. You see the work before launch.

    You get: A working preview

  4. 04
    Launch and documentation

    Every build arrives with a runbook, a recovery plan and a changelog.

    You get: Runbook, recovery plan, changelog

  5. 05
    Operated, not abandoned

    Maintenance and improvements continue after launch, with one accountable owner.

    You get: One person accountable
