Growth hacking is a marketing approach focused on rapid experimentation across marketing channels and product development to identify the most effective ways to grow a business. Growth hackers prioritize creative, low-cost alternatives to traditional marketing.
Growth hacking emerged from startup culture where limited budgets demanded creative approaches to user acquisition. Sean Ellis coined the term in 2010 while helping startups achieve explosive growth.
