In the age of a global, digital economy, everything is in the process of transformation. These changes result in questioning the old economic paradigm and in creating new values and concepts of business operations. One of those alternative forms is The Economy of Communion (EoC) and another one, similar in terminology but rather different in practice is the concept of sharing economy. Comparing these two economic realities, we are looking for similarities and differences, and finding significant contrasting points even if they seem alike. The Economy of Communion (EoC) is a form of social entrepreneurship, representing an international project formed on the initiative of the Focolare Movement. Nowadays, in almost 200 countries around the world, 750 EoC companies operate in the framework of an international network, creating new businesses, social values and humanizing today's global economy.The EoC project has been created to reduce poverty, promote solidarity and brotherhood, and establish new labor and social relations. Brought to life by corporations, this model firstly occurred in practice and then got its scientific and theoretical determinants. The concept of EoC is not just the idea of social entrepreneurship, it is a living socio-economic phenomenon which puts an individual in the center and links employees through values of communion and dignity. It represents the culture of freedom and culture of relationships.Sharing economy (collaborative economy, demand economy, peer-to-peer economy, "gig" economy) is one of the fastest growing trends in the market this decade. It is defined as the business model where activities are facilitated by collaborative platforms that create an open marketplace for the temporary use of goods or services often provided by private individuals.The growth of sharing economy has been strong since 2013 and accelerated in 2015 as large platforms invested significantly in expanding their European operations. It is estimated that collaborative platforms operating in the five key sectors of the collaborative economy, in the EU only, generated revenues of 3.6bn EUR in 2015. These sectors include accommodation (short-term letting), passenger transport, household services, professional and technical services, and collaborative finance.Finally, as the goal of this paper is summarized, after detailed theoretical framework of analyzing concepts of differences and similarities, we have come to a conclusion that the two models are very much different even if they seem synonymous at the start. Both concepts begun with the idea of sharing, but during the time-sharing economy grow into a high profit business enabled by the digital platforms and new shift in millennials behavior.Sharing economy is an idea of operating in a digital environment appropriate for millennials, it is all about the online platform, low costs and digitalization in a way of simplifying the access to open market and creating new services and products. EoC, on the other hand, is a form of social entrepreneurship, representing an international project formed on the initiative of the Focolare Movement.
