Nick Srnicek's *Platform Capitalism* (2017) explores the emergence of a new phase of capitalism characterized by the economic exploitation of data. The book argues that large technology firms have taken the lead in shaping this new phase, with platforms as the central model of business. Srnicek examines the characteristics of platforms, such as their role as market organizers, network effects, cross-subsidization, and governance. He identifies five main types of platforms: advertising, cloud, industrial, product, and lean. The book also discusses trends in platform capitalism, including the expansion of data extraction and the formation of closed ecosystems. While the book provides rich insights into platform capitalism, it has limitations. The typology of platforms is not based on clear criteria, leading to potential overlaps in classification. Additionally, the book focuses primarily on private sector platforms and does not address their diffusion in the public and social sectors. It also overlooks the potential for small and medium enterprises to thrive through platform-based internationalization. Srnicek critiques the partial exploration of elements involved in the formation of the new regime, emphasizing the need to consider other factors such as labor and government norms. He acknowledges the unsustainable nature of some platform business models but also highlights the contributions of industrial and product platforms to capitalist dynamics. The book also addresses the realistic demands of capitalist production and contrasts them with techno-fetishism in sharing economy studies. Overall, *Platform Capitalism* is a valuable source of information on platforms, the current accumulation regime, and offers a critical perspective. It emphasizes that changes in accumulation regimes require not only technological innovation but also organizational innovation. The book contributes to the understanding of long-term transformations in capitalism.Nick Srnicek's *Platform Capitalism* (2017) explores the emergence of a new phase of capitalism characterized by the economic exploitation of data.
