How Brands Grow: What Marketers Don't Know is a groundbreaking book written by Professor Byron Sharp, a renowned marketing expert and director of the Ehrenberg-Bass Institute for Marketing Science at the University of South Australia.

The book challenges traditional marketing theories and provides a new and evidence-based approach to brand growth. Sharp argues that the most effective way for a brand to grow is to focus on being noticed and easily remembered by as many people as possible, rather than just appealing to a select group of loyal customers. This new perspective on brand growth is based on extensive research and real-world examples, making it a must-read for marketers, brand managers, and anyone interested in the science of marketing.
