I co-founded GrowthHacker.TV where I've recorded over 100 episodes and created over 50 original growth recipes that are used by 500 Startups, Y Combinator, Techstars, and startups across the world. I am also the author of The Definitive Guide to Growth Hacking (along with Neil Patel), and I created The Science of Growth Hacking (pdf+mp3). I have growth hacked GrowthHacker.TV to the point that in 6 months, with absolutely zero funding, we've grown to 4 full-time employees and 2 interns. Growth hacking builds companies :)
