Growth Hacking: Complete Strategy Guide

What is Growth Hacking?

Growth Hacking is rapid experimentation across marketing channels and product development to identify the most effective ways to grow a business. It focuses on low-cost, high-impact strategies that can scale quickly, particularly relevant for startups with limited resources.

For startups, growth hacking provides a framework to achieve rapid growth with limited resources by focusing on product improvements, viral mechanisms, and unconventional marketing tactics that can compound over time.
