With the recent outbreak of COVID-19, startup training has rapidly shifted toward mentorship programs in a contactless setting. While studies on the effect and improvement of startup mentorship have continuously been made, contactless startup mentorship has not yet been studied adequately. In this regard, this study aims to examine the characteristics of contactless startup mentorship and to investigate its effect on entrepreneurial intentions and training satisfaction based on the mentorship program at the Yangcheon-Sinjeong branch of Seoul Startup Cafe. Additionally, measures to improve upon contactless startup mentorship were explored based on the results. The results and implications of this study are as follows: First, the more the participants wanted to volunteer to take part in mentorship, the higher the satisfaction and the willingness to rejoin the program, indicating a positive relationship between the mentee's positive attitude and the effect of mentorship. Second, since the participants showed different needs according to their personal circumstances, it is recommended that mentors provide customized mentorship in level or duration by carefully considering the characteristics of each participant. Institutions also need to address the limitations of contactless interactions, such as network connection issues and lack of immediate feedback. Third, as most participants found the one-hour mentoring session not long enough, increasing the number of sessions to at least three is recommended to provide more opportunities for participation. Fourth, publicity for the contactless startup mentorship was generally low. Therefore, it is necessary for institutions to take more active measures to make access to startup mentorship programs easier for those marginalized from access to digital information; this way, they can also take advantage of startup mentorship programs. The results of this study are to be used as basic data for developing startup training systems and be of significance in contributing to strengthening the qualitative capacity of startup support institutions. It is expected that an increase in customized support that can meet the needs of participants will lead to the achievement of the initial goals of startup mentorship: the development of entrepreneurial intentions and success in startups.
