The term “Growth Hacking” has been around for several years and is essentially the art of gaining an avalanche of users and customers via trackable, testable and scalable tools such as emails, pay-per-click ads and blogs instead of blind traditional methods. The growth hacker eliminates big marketing spending and their products gain traction like a spreading virus, multiplying and spreading from user to user. Gaining much for very little.
One of the earliest notable examples of the concept was when the creators of Hotmail decided to add the signature line link, “Hotmail: Free, trusted and rich email service. Get it now.” to every email sent, which meant that everyone who received an email via a Hotmail account would see a link to sign-up. This free and simple tactic moved Hotmail’s user base from a few thousand to 12 Million in a year at a time when there were only approximately 36 Million internet users. (Source: Internet World Stats)
