The entrepreneurial venture is a high-risk endeavor but an effective generator of economic activity that is realized through the entrepreneurial process, whose success depends not only on the abilities and personal commitment of the entrepreneur, but also on the level and adequacy of support provided to them. In this regard, the focus of research in this paper is on supporting the entrepreneurial process. The paper starts from the assumed general Model of Entrepreneurial Process Support, which consists of the entrepreneurial process and support. The entrepreneurial process is represented by its structure (periods, parts, and phases), while support is represented by various forms of financial and nonfinancial assistance. Thus, the key forms of support are first identified based on the structure of the entrepreneurial process, such as workshops, events, announcements, consulting, mentoring, software systems, incubation, networking, and similar activities, and they are then systematized according to the parts of the entrepreneurial process. The resulting structure of support for the entrepreneurial process can be used to determine the most appropriate forms of support in each specific entrepreneurial process, thereby reducing the risk of entrepreneurial venture failure to a reasonable level.
