Growth hacking is an inventive approach to marketing using a variety of tools, data, and high-level experience. It's an iterative, experimental mindset that aims to playfully tease out incremental (or viral) growth from a complex environment. Growth hacking requires a mastery of the product, the marketplace, wide-ranging knowledge of technology, marketing tools, design, psychology, etc. In essence, growth hacking attempts to achieve business results through genuinely new approaches. It's the best kind of marketing, or perhaps, the only kind of marketing.
