Uber. Facebook. Twitter. Airbnb. Netflix. Dropbox. These companies have all benefited from growth hacking. Your single most important job as a founder or employee is to build or create insanely great product or service.

If you are shouting too much about your product, something is wrong.
“Build something 100 people love, not something 1 million people kind of like.” Paul Graham.
