from Sean Ellis & Morgan Brown
"Hacking Growth" by Morgan Brown and Sean Ellis is the definitive playbook for companies seeking to scale quickly without relying solely on massive traditional marketing budgets. This book introduces the concept of "growth hacking" — a discipline that combines creativity, data analysis, and agile methodologies to drive exponential growth in users, customers, and revenue. Conceived and perfected at companies like Dropbox, Airbnb, Facebook, and LinkedIn during their hypergrowth phases, this approach has revolutionized how startups and tech companies approach customer acquisition and retention. It is required reading for growth hackers, digital marketers, product managers, startup founders, and any professional responsible for growth metrics. The authors, industry pioneers, share practical frameworks, real case studies, and proven processes that any organization can adapt to build sustainable growth machines. It is especially relevant for teams operating with limited resources but unlimited ambitions, demonstrating that growth can be a systematic and replicable process, not just a matter of luck or unlimited venture capital.
BOOK SUMMARY
Hacking Growth presents a complete system for building growth teams and processes that have proven to work at the world's most successful digital companies.

- Activation: Getting users to have a first valuable experience ("wow moment")
- Retention: Keeping users engaged and coming back
- Revenue: Monetizing the user base effectively
- Referral: Turning satisfied users into ambassadors who bring new users
3. The growth team: Structure, roles, and dynamics of multidisciplinary teams dedicated exclusively to experimentation and growth optimization.
4. Agile experimentation process:
- Opportunity identification through funnel analysis
- Experiment prioritization (ICE framework: Impact, Confidence, Ease)
- Rapid test execution
- Results analysis and decision to implement or discard
- Documentation and sharing of learnings
5. The "wow moment": Identifying and optimizing the specific moment when a user understands the real value of the product, key to activation and retention.
6. North Star Metric: Identifying the single metric that best captures the value delivered to users and drives sustainable growth.
7. Scalable acquisition channels: How to identify, test, and optimize the channels that offer the best return on investment for each business model.
WHY I RECOMMEND READING THIS BOOK? By Francisco Santolo
As a founder who has had to grow companies with tight budgets, "Hacking Growth" was like finding the instruction manual I never knew I needed. Ellis and Brown demonstrate that growth isn't black magic or a matter of luck: it's a science that can be learned and systematized.
What I value most about this book is its practical approach. They don't sell you smoke with success stories without context; they give you frameworks you can implement this week. The concept of "North Star Metric" transformed how my teams align on common objectives. And the continuous experimentation methodology allowed us to stop arguing opinions and start letting the data speak.
I especially recommend it to startup founders in growth phase and product/marketing teams who feel they're working hard but not seeing proportional results. This book teaches you to work smart, not just hard.
