Breakfast, Big Data, and the Art of Not Creeping People Out: Kellanova’s Clean Room Chronicles
Kellanova was facing falling Special K cereal sales in the UK, so they used a special tool called a data clean room to mix data from different sources without breaking privacy rules. This let them see which groups of shoppers really wanted their cereal, so they could send the right ads to the right people. Thanks to this smart targeting, Special K sales jumped by 36% among premium shoppers, and the company made millions more in sales. The key was focusing on solving the real problem, not just using new technology for its own sake, and being flexible when things got tricky. This new way of working helped other brands in the company succeed, too.
