If you’ve spent any time in the startup world, you’ve probably heard the term “growth hacking.” It sounds flashy, almost like a Silicon Valley buzzword—but at its core, it’s about one thing: finding innovative, creative, and data-driven ways to grow a business quickly and sustainably.
Enter the Growth Hacker—the professional whose job is to blend marketing, product strategy, and analytics into a single mission: growth at all costs, but without wasting resources.
