Platform Based Collaborative Economy (PBCE) is new social and economic systems that include exchange of human and physical resources through Internet platforms where access provision is transferred. In the last 10 years, many forms of the PBCE have emerged, but a definition, which is fundamental (for example to legislation), has not yet been made. In addition in agriculture, the phenomenon of “co-operation” is not new, but platform-based implementation however has not yet general. By analysing international literature and exploratory research, the categories of PBCE and demand side oriented economy model were systematized, and then, through examples, the categories of PBCE in agribusiness were analysed. The PBCE is a demand-driven business model based on the information technology platform. The economic activity created by digital marketplaces and technology companies - to meet consumer demands - takes place through the platform for immediate access to goods and services. On digital marketplace product or service information is provided by multiple third parties, whereas transactions are processed by the marketplace operator. Based on Internet data collection, the main areas of agricultural application of the PBCE were explored and presented with examples. The spread of new economic system within agriculture can be achieved in two main ways: by sharing assets and crowdfunding. Practical implications of this article that clearly defined the concept of PBCE, and its sub-areas, first - to our knowledge - the categories of crowdfunding. Also first, by presenting examples, the article summarized the field of agricultural application in the field of PBCE.
