A friend of my is crowdsourcing a book on ‘Growth Hacking’. Whilst I prefer the archaic term ‘marketing’ he’s also selling to the startup world, where a little buzzword bingo has to help with sales!
I’ve seen the original presentation (live!) that the book will be based on and if that’s anything to go by the book is going to be very ‘tactical’ - i.e. useful. If you’re interested, it’s certainly worth $25.
