Robert Passikoff

Robert Passikoff is best known as the creator of the Customer Loyalty Engagement Index (CLEI) and the Brand Keys methodology, which uses psychological and emotional engagement metrics to predict consumer behavior and brand performance. His work has fundamentally shaped how marketers understand the relationship between brand loyalty, advertising effectiveness, and purchase intent — making him a respected voice at the intersection of consumer research and advertising strategy. His models are widely cited for their predictive accuracy, often forecasting market shifts before traditional tracking studies can detect them. Passikoff founded Brand Keys in 1984, building it into a leading brand loyalty and consumer engagement research consultancy. Over four decades, he has worked with hundreds of major brands across retail, media, technology, and consumer goods, helping them understand how emotional engagement drives loyalty and, ultimately, advertising ROI. His annual Brand Keys Sports Fan Loyalty Index and Customer Loyalty Engagement Index have become industry benchmarks, regularly covered by major media outlets including The Wall Street Journal, The New York Times, and USA Today. As a thought leader, Passikoff has authored books on brand loyalty and contributed extensively to industry publications, positioning Brand Keys as a go-to resource for CMOs and advertising strategists seeking to connect brand investment to measurable consumer outcomes. His influence extends into the AdTech ecosystem through his advocacy for emotion-based and engagement-driven metrics as alternatives or complements to purely digital performance metrics.
