The Fintech sector is one of the most dynamic and innovative areas within the global financial indus-try. In recent years, the integration of advanced technologies, unconventional business models, and emerging competitive dynamics has profoundly reshaped the financial landscape, creating unprece-dented opportunities and challenges. This book is positioned within a constantly evolving context, aiming to provide a structured and in-depth analysis of the key trends redefining the sector. The focus extends beyond technological advancements and regulatory frameworks to encompass an evaluation of Fintech startups and en-terprises, highlighting the increasingly significant role of soft indicators (governance, management quality, regulation, and ecosystem). Furthermore, it explores the relationship between Fintech com-panies and traditional financial institutions, with particular emphasis on collaborative strategies, M&A activities, and emerging business models. The distinctive value of this book lies in its balanced approach between theory and practice, integrat-ing academic rigor with practical implications for investors, policymakers, and industry profession-als. Ultimately, it seeks to provide essential analytical tools and insights to understand the evolution of Fintech, guiding the reader through a critical and structured examination of a sector undergoing continuous transformation. The research behind this work draws upon insights and field observations from the European Fi-nancial Services Tech Hub of SDA Bocconi, a leading platform dedicated to the intersection of innovation, financial services, and technology. The Hub's empirical base and strategic collaborations provide a valuable vantage point on the sector's ongoing transformation.
