Headquartered in London, Realeyes is an eye-tracking and emotion measurement platform that uses AI and machine learning to gain insight into human behavior and expression. Their clients include Buzzfeed, Coca-Cola, Conde Nast, eBay, Mars, and Publicis Groupe, among others. Realeyes uses front-facing cameras, computer vision and machine learning technologies to detect attention and emotion among opt-in audiences as they watch video content. ClickZ recently spoke with Max Kalehoff, VP of Marketing & Growth for Realeyes to discuss the company's innovative technology and the capabilities they bring to marketers and publishers. Kalehoff learned about Realeyes after co-leading a panel presentation with Realeyes's CEO at the Sustainable Brands Conference in 2017.
