03 / WORKSHOP

Necessity is the mother of invention.

Small needs make the best inventions.
If we need it, so do the quiet many.
Wouldn’t it be nice? Let’s just build it.

  1. 01 DAY 0

    Wishing

    Our own niche need.

    If no one is building it, even better.

  2. 02 DAY 0

    Shipping

    Built with agents, out the same day.

    Agents work in parallel, so the first version is live while the idea is still fresh.

  3. 03 DAY 1 →

    Dogfooding

    We use it before anyone else.

    It runs in our own day first. Whatever bugs us gets fixed first.

  4. 04 DAY N

    Finding the others

    Everyone who quietly needed it too.

    A small market with no rivals beats a crowded one. The tools that find their people grow into businesses.

04 / HOUSE VIEW

The wheel already exists.
Take it.
