Start here

Find the uncertainty that matters now.

Use your current evidence, not your ambition, to choose the next move.

Startups move through recognizable stages, but not on a fixed schedule. Some questions deserve attention before others.

Three rules before you begin

  1. 01

    Evidence before effort

    Use the cheapest credible test before making the most expensive commitment.

  2. 02

    One customer before every customer

    A narrow first customer makes the problem, message, product, and channel easier to understand.

  3. 03

    A complete outcome before more features

    Make one valuable job work from beginning to end before expanding the product.
