The aim of the article is to form a number of recommendations based on the comparative analysis of digital consulting organization technologies in European countries regarding the organization of communication interaction between subjects of international scientific and technical cooperation in this area for the intensification of international scientific and technical cooperation in Ukraine. Analyses results. The article analyzes the technologies of digital consulting organization in European countries. For a comparative analysis, portals were selected that most successfully implemented the process of providing digital counseling using specialized national contact points for obtaining grants within the framework of such European Union framework programs as "Horizon2020" and "Horizon Europe", which are defined as the largest transnational grant researches funding programs in the field of international scientific and technical cooperation. The article improves the method of applying digital technologies to intensify international scientific and technical cooperation through the use of specialized consulting methods, which are aimed at Ukrainian participants in grant funding of scientific research, which allows to increase the level of involvement of Ukrainian science in the European scientific space. The practical significance of the research lies in the development of a proposal for the organization of communication interaction between the subjects of international scientific and technical cooperation in the field of the use of digital consulting technologies for the intensification of international scientific and technical cooperation in Ukraine. Conclusions and directions for further research. As part of the research objective, an analysis of the portals was carried out on which, based on specialized national contact points, consultations using digital technologies are implemented for the largest transnational research funding programs in the world - the EU Framework programs for research and innovation "Horizon 2020" and "Horizon Europe" for a number of countries, in particular: Belgium, Austria, Poland.
