1. Introduction

A startup is a newly established business begun by an entrepreneur to seek, develop, and validate a scalable economic model, transforming a project into a hopefully viable commercial activity. Bringing ideas to fruition is the ultimate target of successful startuppers. The valuation paradigms represent a central issue for any startupper seeking external finance, either from “family and friends” or through a wider and professional placement, from equity crowdfunding to venture capital or private equity underwriting. This book represents an updated guide to both practitioners, students, and academics about the trendy valuation patterns of the startups. Empirical cases, with industry applications, show how the theoretical background can be applied to real situations.
