Hacking Growth
Built around acquisition, activation, retention, and monetization: how cross-functional growth teams use data and rapid experiments to drive growth.
This is the fifth book of this year’s Zhou Zuoluo reading club. It’s mainly about product growth, and for a programmer like me it’s genuinely worth reading.
1. Overview
Hacking Growth is written by Sean Ellis, who coined the concept. Using real cases from companies like Facebook and Airbnb, it systematically explains how to break through the boundaries of traditional marketing and drive growth with data analysis and technology.
The book is built around the user lifecycle of “acquisition, activation, retention, and monetization,” explaining in detail how to build a cross-functional growth team and how to quickly find product-market fit (PMF) through A/B testing.
For readers who want to understand how internet companies use technology and data to achieve exponential expansion, it’s a rare methodology handbook.

3. Summary
If you don’t get positive feedback from something, it’s hard to keep going. So when beginners build websites, they should target new and trending keywords, launch fast, and use some of this book’s methods to acquire users and monetize.
Rapid experimentation is a hard requirement of growth hacking, and building websites needs speed too: even if it’s just a landing page, capture the traffic first, then keep iterating. Even if the results aren’t good, that’s fine. At least we gain experience in the process, and next time we launch a site we’ll handle it with more ease.
