The paper presents the use of EU funds for the development of high-tech projects that are of great importance for the development of any economy. In the period from 2014 to 2021, Croatia had a total of 10.676 billion euros at its disposal, and managed to withdraw 6.79 billion euros. Croatia uses funds from the European Structural and Investment Funds for projects that contribute to improving the lives of its citizens. These are projects that promote democratization and raise awareness of human rights, projects that deal with environmental protection and major infrastructure projects. Based on an interview with Professor Marinko Džepin, Head of the Administrative Department for Economy, Development and Projects of the European Union of Samobor and Marina Delišimunović, Senior Expert Associate for Economy and Development Projects in Samobor, it can be concluded that smaller cities like Samobor recognize the importance withdrawal of funds from EU funds, and the importance of investing in high-tech projects. An example of this type of project is the project Mali Tehnopolis Samobor, which is equipped with the latest generation 3D scanner and 3D printer. This technology has enabled users to use new innovative solutions for product and service development. By investing in technological projects through the procurement of high-tech equipment, the foundations are laid for the development of entrepreneurship oriented to knowledge, technology and innovation.
