4. Growth Hacker is the new VP of Marketing
by Andrew Chen"http://andrewchenblog.com/2012/04/27/how-to-be-a-growth-hacker-an-airbnbcraigslist-case-study/
"Growth hackers are a hybrid of marketer and coder, onewho looks at the traditional question of “How do I getcustomers for my product?” and answers with A/B tests,landing pages, viral factor, email deliverability, and OpenGraph. On top of this, they layer the discipline of directmarketing, with its emphasis on quantitative measurement,scenario modeling via spreadsheets, and a lot of databasequeries. If a startup is pre-product/market ﬁt, growthhackers can make sure virality is embedded at the core of aproduct. After product/market ﬁt, they can help run up thescore on what’s already working."
