Adoption & Behavior
Adoption & Behavior
The Sticky Product spine — why people keep using products and what drives retention from first use.
Most product teams optimize for acquisition. They polish landing pages, fine-tune ad spend, and celebrate signups — while the real job happens after the first click. Adoption is not a funnel step. It is the moment the product becomes part of the user's progress.
This book is the behavior layer. The first fourteen minutes, the everyday-use loop, the metrics that actually predict stickiness, and the design patterns that make products feel inevitable rather than optional. Every pattern is grounded in the forces that drive real human behavior.
Each article runs the same loop: name the behavior, see the force, design the moment, measure the progress, keep the artifact. No growth-hacking gimmicks, no vanity metrics. Built to make products people pull up tomorrow.
