The dynamic business environment of today demands digital transformation as an inevitable factor shaping the development of various industries and sectors, including the financial and insurance sectors. While banks and related financial institutions have largely experienced transformation through the digitalization of their services, traditional models in the insurance sector have remained somewhat resistant to this trend. Although the financial sector has relatively quickly adapted to the demands of today's digital environment, the insurance sector faces challenges in its transition towards digital transformation.. It has been proven that digital platforms and ecosystems play a crucial role in enhancing business operations by providing innovative ways of interacting with customers and opening new business opportunities. However, the insurance sector often features traditional models based on conservative approaches and long-standing practices, which slow down the process of digital transformation. These limitations could result in slower adaptation to new technologies and innovative business models, potentially leading to a loss of competitiveness and lagging behind the dynamic changes in the market. In this context, a critical question arises: How can traditional models in the insurance sector bridge the gap towards digital transformation and benefit from the opportunities provided by digital platforms? This thesis explores precisely this topic, analyzing key concepts of digital transformation and examples of successful implementation of digital platforms in the insurance sector, while also conducting research on the possibilities of applying platform models in the Republic of Croatia. One of the goals of this thesis is to provide a more detailed insight into the potential for digital transformation in the insurance sector, as well as to identify the necessary steps for achieving technological and business innovations in this sector. Therefore, the concept of the platform economy is first analyzed in detail, exploring the basic principles of digital platforms and their ecosystems, while providing insight into successful implementation examples worldwide. Furthermore, the importance of the concept of digital transformation is emphasized in the context of modernizing the insurance sector, distinguishing it from the concept of digitalization, and exploring its key aspects and implications. InsurTech innovations are also presented in detail, with a thorough analysis of new technologies that are transforming the banking and non-banking financial sectors in general, and a comprehensive overview of the current state and trends both globally and in the domestic market is provided. Specific case studies of successful digital platforms in the insurance sector are examined, including the most well-known global example, Lemonade, as well as LAQO, the first digital insurance in the Republic of Croatia. Through empirical research conducted on 235 respondents, the potential for digital transformation of the insurance sector through the model of digital platforms is analyzed by examining respondents' opinions and attitudes on whether the platform model could be a solution for the digital transformation of the insurance sector. The respondents' inclination towards using digital platforms for purchasing insurance products or contracting insurance services in the Republic of Croatia is also examined. A descriptive study was conducted using an online survey questionnaire (as the research instrument), and the primary research aimed to answer three research questions. After the research has been conducted, it can be concluded that respondents are inclined towards the platform model as an optimal solution for the digital transformation of the insurance sector, indicating a growing awareness of the benefits that digital platforms bring, as well as the need for their implementation to ensure the insurance sector successfully adapts to contemporary technological trends and market demands.
