Unlike traditional marketing agencies, growth hacking agencies don’t play the guessing game. Growth hacking agencies measure, analyze, test, compare, refine, and repeat to reach their goal. A growth hacking agency and its growth hackers should be creative minds, tech-savvy, logical, and great problem-solvers.

To understand what a growth hacking agency does, you first need to understand what growth hacking is.

Growth hacking began to develop during the early 2010s. During that time,  a large number of startups rose. Those startups that needed growth and adoption at an early stage; growth hacking was the solution to their need. As Ryan Holiday, author of Growth Hacker Marketing puts it: “A growth hacker is someone who has thrown out the playbook of traditional marketing and replaced it with only what is testable, trackable, and scalable.” Growth hacking frames the user acquisition process through the “funnel” metaphor, as in Acquisition, Activation, Retention, Revenue, Referral.

The heart of growth hacking is the relentless focus on growth as the only metric that truly matters. Airbnb, Uber, Twitter, Facebook, Dropbox, Pinterest, YouTube, Hotmail, Udemy, Instagram and Google are some of the companies that have used growth hacking techniques to grow and become the companies we all know today.

Since the early 2010s, a lot of growth hacking agencies have appeared. Since then, many of them have disappeared. However, some of them not only survived but also stood the test of time. This doesn’t mean that there are agencies that have brought great results for their clients in spite of their young age.

With no further ado, here are the Top 10 growth hacking agencies for 2019.
