Watch a bunch of interviews of founders of successful companies, and here’s what you don’t hear:
We tried eight different marketing channels — AdWords, Facebook, Twitter, Pinterest, social media, events, retargeting, SEO, guest-posting, PR, and so on. All of them worked a little bit, so together it was substantial — a trickle from each that added up to a river. Then we optimized each of them, improving each a bit more every month, and sure enough revenue doubled every year.
