"A growth hacker is not a replacement for a marketer. A growth hacker is not better than marketer. A growth hacker is just different than a marketer. Every decision that a growth hacker makes is informed by growth. Every strategy, every tactic, and every initiative, is attempted in the hopes of growing. Growth is the sun that a growth hacker revolves around."
