When we started this book, we found it a little bit dense and plain at the beginning. However, the more we read it, we started noticing how enriching it was. Whether or not you are working as an entrepreneur, this handbook will allow you to grow your business acumen and will give you a deeper vision into different business models of multiple industries. Interestingly, the canvas used in this book was the one used by Ash Maurya to adapt the Lean Canvas used in Running Lean. It is important to note, that we recommend this canvas if you have been working in your start-up and has reached a certain level of maturity. Otherwise, we recommend the Running Lean one.
