The Metaverse has been everywhere for a year and the announcement of the name change from Facebook to Meta in October 2021. Fad or real possibility, that is the question that many insurance players are trying to clarify. It is true that the term is vague, on the border between science fiction, technology and real possibilities. The billions invested and the diversity of use cases make the understanding of the metaverse phenomenon essential for all insurance players: educational organizations, consulting firms, brokers, insurers, reinsurers, insurers and general agents. To distinguish the useful from the accessory, to be able to formulate a strategy and execute it, such is the purpose of this book. It addresses the use of metaverses, placing the user and consumer at the center through an analysis of the impact on insurance compared to other industries. Operational thanks to numerous examples, the book is aimed at students, professionals, managers and leaders who are aware of the essential role of the metaverse as a lever for transformation and growth.
