Just over a year ago, managers at Kraft believed that their Velveeta brand had only moderate growth prospects. With the consumer migration toward natural and organic products, sales of Velveeta—a processed, unrefrigerated “cheese food”—had languished. The customers who did buy it typically used it once or twice a year, usually to make a party dip. But as we began working with Kraft and analyzing supermarket scanner and consumer panel data, we found a hard-core group of Velveeta fans. They constituted 10% of buyers but accounted for 30% to 40% of revenue and more than 50% of profits. In focus groups, these buyers—whom we dubbed superconsumers—said that they think of Velveeta as superior cheese. They love the way it melts smoothly and easily, and they have myriad uses for it, ones that range far beyond dips (one person even claimed to use a little when making fudge). After we finished questioning the superconsumers, they traded recipes, e-mails, and phone numbers with one another—building friendships around their shared passion for Velveeta.
