This book does exactly that: experienced entrepreneurs, executives, and data scientists share their expertise. I want to encourage readers to use the insights of this book as a compass & in a world flooded with data yet longing for clear orientation. The strategies and use cases discussed here will inspire you to see Customer Intelligence not as a technical obligation but as a central element of your corporate philosophy. Ultimately, it is not the amount of data that determines business success, but how intelligently it is used." (Prof. Dr. Dr. h.c. mult. Hermann Simon, Simon-Kucher & Partners)
