Hacking Growth offers a comprehensive playbook for companies to achieve rapid, scalable growth through innovative experimentation and cross-functional collaboration. Sean Ellis, credited with coining the term "growth hacking," and Morgan Brown, a growth strategist, distill their insights and experiences from working with successful startups like Dropbox and Airbnb. The book is divided into two sections: the method behind growth hacking and a tactical playbook for implementing it. At its core, growth hacking combines marketing, product development, and data analysis to uncover and optimise growth opportunities.
