Social entrepreneurship, as a subset of entrepreneurship as a whole, is becoming a matter of increasing importance in modern society. The main characteristic of social entrepreneurship is reinvesting part of your profits in projects that are beneficial to society, which results in success not being purely financial but having a significant influence on social, ecological and economic development. In contrast to traditional entrepreneurship, social entrepreneurship focuses on solving social issues, integrating marginal social groups and creating sustainable solutions to ensure the well-being of the community. This thesis aims to present the concept of social entrepreneurship with emphasis on its development in the Republic of Croatia and a successful example of such entrepreneurship in the social cooperative "Humana Nova". This model of entrepreneurship presents an alternative to traditional business practice and contributes to addressing key social issues by using innovative and responsible solutions.
