Four steps, no surprises

One senior analyst owns your project from the first call to the handover.

  1. We listen

    A senior analyst maps how your business really works, in your words. Thirty minutes, free.

  2. Your offer in 48 hours

    What we build, when it goes live and exactly what it costs. The price doesn't move once we start.

  3. We build, you watch

    AI builds to the plan under senior supervision. Every week you see a live demo of working software.

  4. People check, then hand over

    The analyst tests every screen by hand and the tech lead reviews the code. You get the code, the documentation and three months of hypercare.

Four app screens, each more finished than the last

Nothing reaches you unchecked

Two people and two automated checks stand between the AI and your business.

Etheria's board, recreated with real tasks from the DiggyParty delivery.

Five promises, in writing

of your money back if it doesn't work as agreed

The price is fixed before we write a line of code, and it is typically 40–50% below agency quotes.

  • A fixed price before any code

  • Code, docs and IP handed over on delivery
