Definition of product growth hacker

Best definition I’ve seen of growing products on the web.

A growth hacker is someone who has thrown out the traditional product playbook and replaced it with only what is testable, trackable, scalable…while their marketing brethren track vague notions like branding and mindshare, growth hackers relentlessly pursue users and growth (source: Ryan Holiday). My take: not sure this works for enterprise all the time, but it’s a nice idea.
