Chapter 4: Experiment

1. The experiment phase: it begins with a clear hypothesis that makes predictions about what is supposed to happen. Startup experimentation is guided by the startups vision. The goal of every startup experiment is to discover how to build a sustainable business around that vision. Even when experiments produce a negative result, those failures prove instructive and can influence strategy. In the lean startup model, an experiment is more than just a theoretical inquiry; it is also a first product.

2. The two most important assumptions entrepreneurs make are:

   • • The value hypothesis – test whether a product or service really delivers value to customers once using it.
   • The growth hypothesis – test how new customers will discover a product or service.
