David Aaker- The OG of Brand

David Aaker is widely regarded as the father of modern branding. Over a five-decade career, he transformed brand from a communications tool into a strategic asset. His groundbreaking concept of brand equity, introduced in Managing Brand Equity (1991), reframed how businesses understand value — not just through products, but through perception, loyalty, and meaning. He followed with Building Strong Brands (1996), which introduced the Brand Identity System, and later with Brand Leadership (2000), co-authored with Erich Joachimsthaler, which cemented the idea of brand as a driver of business strategy.

Beyond his role as a professor at Berkeley’s Haas School of Business, Aaker has shaped practice as well as theory. As Vice Chairman of Prophet, he’s advised global brands on identity, portfolio strategy, and brand relevance. His frameworks — from signature stories to brand architecture — have become foundational tools for strategists around the world. In 2015, he was inducted into the American Marketing Association Hall of Fame for his lifetime contributions to marketing thought.

Among those deeply shaped by Aaker’s work is Scott Galloway, who studied under Aaker at Berkeley in the 1990s and later co-founded Prophet. Galloway has said, “There would be no me without David Aaker,” a testament to Aaker’s profound influence on the next generation of brand thinkers. What Aaker pioneered — brand as belief system, as organizing principle, as strategic lens — remains more relevant than ever in a time when differentiation is fleeting and cultural resonance is everything.
