Companies in the last century encouraged the seller to be aggressive in order to achieve positive sales results. However, as can be found in this new material, this was a serious mistake caused by ignorance, which is evidenced thanks to the contributions of neurosciences. This publication's main objective is to lead the seller, and the reader in generally, through a process of change, which starts from a reflection on its mission and personal development. In this sense, this book provides the necessary support to become the new salesmen of the 21st century: the neuro-sellers. The Neuroventas book is aimed at all those who work as salespeople, sales managers, coordinators and managers in the commercial area.
