“It’s a common misconception that Charles Darwin coined the phrase ‘survival of the fittest’. It was actually first mentioned by Alfred Russel Wallace but it’s also a selective quote. What both Darwin and Wallace actually meant was that species that are more adaptable to change are those that survive. It’s the same for companies. Organisations that are able to adapt quickly and grow (despite continual change, competition and threats) will both survive and flourish. Chris shares a thorough blueprint for starting, building and massively accelerating the growth of your company whilst continually adapting to your own growth and changes in the marketplace.”

– Craig Sullivan, CEO at Optimise Or Die

“I was probably one of the most excited people waiting for Chris’s book to be published. His pragmatic mindset and iron discipline to focus on what really brings value in business make him very unique as an author. And boy, did he deliver with this one! Growth hacking is an excellent methodology, but done in isolation from business strategy and objective it can easily change to a rat race of experimentation only to leave people overwhelmed and confused. And that happens a lot. It is probably not your fanlight either. As a seasoned professional and entrepreneur who has seen such bottlenecks and traps in practice, Chris offers practical frameworks on how to stay laser-focused on things that bring value to the business. It personally encouraged me to create more modular assets such as online courses, checklists, and innovative teaching formats to see a more predictable and sustainable revenue stream unlike in consulting business. I would warmly recommend it to business consultants, to experienced professionals and entrepreneurs, since the book offers strategic frameworks to elevate growth models and is, to my knowledge, the first growth book that focuses on strategic and entrepreneurial aspects of implementing and sustaining a growth program in the company.” 

– Maja Voje, Best-Selling Instructor on Udemy

“In today’s competitive world, you need every advantage you can possibly get. Therefore, I dare to say that this inspiring book on growth hacking is the most helpful book for entrepreneurs and marketers TODAY. Companies should always be on the lookout for the next growth opportunity to monetize. That’s easier said than done, of course. With ‘Structuring for Extreme Revenue Growth’, however, Chris breaks it down into understandable and applicable steps, showing you how growth can and should be structured. He lets us understand the essence of Algorithmic Growth Thinking, a phenomenon and helpful metaphor I hadn’t heard of ever before. Above all, the book reveals Chris’s own story. It explains how he became who he is and how he consistently gets where he is going.”

– Marieke Pijler, Founder Brand Density

“This book is a must-read for every professional in Growth when
you want to make a significant impact in your company.”

– Sophia Eng, Senior Growth Marketing Manager at Smartsheet

“Too many books on growth hacking focus on the hacks or optimizations that helped grow other businesses. But you can’t replicate those quick wins in order to grow long term. That is why Chris’ unique perspective on growth is so powerful: he deconstructs growth down to its core principles to help you build a strong long-term growth strategy. Not only that, he also shows you how to immediately improve your growth approach and create more impact in the short-term too.”

– Daphne Tideman, Head of Growth at Heights and Author of Growing Happy Clients

Structuring Extreme Revenue Growth is a book that enables businesses, young and established, to re-focus and re-architect their models in such a way that growth is imminent. If you need more guidance beyond that, my suggestion would be to bring Chris into the business and have him work with your team.
