A growth hacker is a person whose true north is growth. Everything they do is scrutinized by its potential impact on scalable growth. Is positioning important? Only if a case can be made that it is important for driving sustainable growth (FWIW, a case can generally be made).
The good news is that when you strip away everything that doesn’t have a direct impact on growth, a growth hacker should be easier to hire than a VP Marketing (or maybe an insider already has the needed skills). I’ve met great growth hackers with engineering backgrounds and others with sales backgrounds.
The common characteristic seems to be an ability to take responsibility for growth and an entrepreneurial drive (it’s risky taking that responsibility). The right growth hacker will have a burning desire to connect your target market with your must have solution. They must have the creativity to figure out unique ways of driving growth in addition to testing/evolving the techniques proven by other companies.
An effective growth hacker also needs to be disciplined to follow a growth hacking process of prioritizing ideas (their own and others in the company), testing the ideas, and being analytical enough to know which tested growth drivers to keep and which ones to cut. The faster this process can be repeated, the more likely they’ll find scalable, repeatable ways to grow the business.
