A short but sweet introduction to growth hacking with a focus on the success stories of the past few years, I found Growth Hacker Marketing served up information quickly and concisely and left plenty of food for thought on how others can hack the growth of their own product. While it would have been more helpful to hear more unusual examples - not everybody has a product that has mass appeal - I found my mind ticking over with lots of new ideas after reading this, always a positive!
