Your Review





Solid advice but hard to implement without a big team.





The book explains how to build a cross-functional growth team that breaks down silos between marketing, product, and data teams. I realized my company wastes money because departments work separately instead of aligning on user needs. Ellis argues that without this unified engine, even clever hacks fail long-term. He uses examples like BitTorrent, where hiring a growth manager unified the team, leading to 100 million downloads and 300% revenue growth within months. This insight helped me understand that silos kill growth faster than lack of budget, so I plan to propose a similar structure at my mid-sized business to align everyone around a single North Star metric instead of chasing vanity stats like daily active users that don't reflect real value for customers.





This book changed how I think about growth for the better.





Finally a playbook that explains how to build a real growth engine instead of just chasing viral hacks.





Hacking Growth changed my entire approach to building products.





This book taught me how to build a cross-functional team to stop working in silos and actually drive sustainable growth.





This book helped me stop guessing and start testing for real growth.





The focus on user-centricity over vanity metrics is refreshing, especially for marketers who are often pressured to chase clicks and likes instead of actual user retention.





Great playbook for building sustainable growth without relying on expensive ad spend.





A few chapters really stood out. Enjoyed the pace.





The framework for building a growth engine is solid, but the section on enterprise growth hacking felt too focused on bureaucracy rather than the agile experimentation I was hoping to learn.





Essential reading for anyone struggling to move beyond guesswork in their growth strategy.





Optimizing existing channels is smarter than chasing new ones, but the advice on personalization requires tools I simply do not have access to in my current startup stage.





The ICE model for prioritizing ideas is practical, yet I struggled to see how a small team without data analysts could accurately calculate confidence scores for every proposed experiment.





Reading about the indispensability survey made me realize I need to stop chasing vanity metrics and focus on whether my product actually solves a core user problem.





The framework for building cross-functional growth teams is very clear and practical. I found the section on breaking down silos between product and marketing especially useful, as it explains exactly how to align departments around a single North Star metric instead of working in isolation. The examples from companies like BitTorrent and Twitter helped me understand how to implement this structure in my own organization without needing a massive budget. While the book covers advanced topics like custom growth equations and cohort analysis, the core message that sustainable growth relies on user-centric data rather than guesswork resonates deeply. It's not just about running quick viral experiments; it's about creating a systematic engine where every decision feeds into long-term retention and value. I appreciate how the authors emphasize validating the 'aha moment' before scaling, because trying to grow a product that doesn't solve a real problem is a waste of resources. The step-by-step process for running the indispensability survey is simple yet powerful, making it easy to test product-market fit early on. Overall, this book provides a comprehensive roadmap for moving from stagnant growth to predictable, scalable results through iterative learning and collaboration.





Good read but the cross-functional team advice feels hard to apply in my current small office setup.





I struggled with siloed teams until reading this chapter on cross-functional collaboration, which showed me exactly how marketing and product teams should align their goals to stop wasting budget on features nobody wants, turning my chaotic department into a unified engine that actually drives retention instead of just chasing vanity metrics like clicks.





This book is essential for anyone trying to move beyond guesswork, as it clearly outlines the step-by-step process needed to validate value before investing in growth.





The iterative learning principle is the most valuable takeaway, reminding me that every failed experiment teaches something crucial about what users actually need.
