How a project runs

You see working software every iteration, not just status reports.

  1. Brief

    Tell us the problem. We ask the questions that shape scope and risk.

  2. Estimate in 24 h

    Scope, timeline and price within 24 hours.

  3. Prototype

    A clickable prototype or a technical spike before the full build.

  4. Iterations with demos
