How to Build Self-Improving Products
A customer asks for something. You build a small working answer. They try it in their own workflow. What happens next tells you what to improve.
This book explains how we use customer evidence, practical research, and working releases at BuildBetter to make that loop repeatable.

Choose the right experiment
Use conversations, grounded personas, surveys, prototypes, and working releases to answer specific questions.
Follow the release through
See whether customers can complete the job, return when they need it, and benefit from the next iteration.
