“Growth Hacking: 8 weeks to double the number of your prospects” is a book that is distinguished by its ultra-practical and results-oriented approach. We feel that Frédéric Canevet and Grégoire Gambatto are not theorists, but practitioners who have applied and refined these techniques in the field.

The highlights of the book:

  • The program in 8 weeks : a clear, structured and progressive format that allows immediate application of lessons. Each week has a specific objective and concrete actions to put in place.
  • The focus on practice : the book is full of templates, checklists, tools, and real examples. It's a real guide to growth hacking, not just a theoretical essay.
  • Adapting to the French context : unlike many books on growth hacking that focus on Silicon Valley startups, this one takes into account the specificities of the French market and ecosystem.
  • The balance between acquisition and retention : the book is not content with techniques to acquire more prospects, but also emphasizes the importance of activating and retaining them for sustainable growth.

If the book has a limitation, it is that it focuses mainly on online businesses, especially SaaS and e-commerce. Some specific tactics may be less relevant for more traditional businesses or BtoB models.

In addition, the ultra-dense and information-rich format can sometimes seem a bit overwhelming, especially for complete beginners. Perhaps the book would benefit from offering more contextualization and explanation of some basic concepts.

But these criticisms are minor compared to the immense value this book brings. “Growth Hacking: 8 weeks to double the number of your prospects” is an indispensable resource for any entrepreneur, marketer or growth hacker looking for proven and actionable strategies to boost their growth.

Things to remember

  1. Growth hacking is not a one-off tactic, but a global philosophy that must permeate the entire company. It requires an alignment of all teams around the objective of growth.
  2. The AARRR framework offers a structured roadmap for auditing and optimizing your entire funnel, from lead acquisition to revenue generation.
  3. In acquisition, content is king. A quality blog, optimized for SEO and promoted intelligently, can be a lead machine.
  4. Activation and retention are just as critical as acquisition. Invest in careful onboarding and proactive customer success.
  5. Data is the fuel for your growth machine. Put the right analytics tools in place and develop a culture of continuous measurement and experimentation.
