Mentoring programs are important not only for business but also to serve as a bridge between business and academia. Many studies have delved into the factors that contribute to successful entrepreneurial performance and many have led to recommendation that on top of financial support for youth entrepreneurs, business mentoring programs are an essential component which needs to be seriously considered to better position the entrepreneurial ventures for success. Although research on mentoring programs is abundant, there is limited research that explicitly compares and contrasts the influence of various mentoring programs on enterprise performance. The main objective of the study was to analyze the influence of mentoring programmes on the performance of youth owned enterprises in Nairobi County, Kenya. In order to accomplish this, these specific objectives were used in the study: to evaluate the influence of one-on-one mentoring programs have on the performance of youth owned enterprises in Nairobi County, to examine that influence group mentoring programs have on the performance of youth owned enterprises in Nairobi County, to establish the effect of peer mentoring programs on the performance of youth owned enterprises in Nairobi County and lastly to assess the influence of virtual mentoring programs on the performance of youth owned enterprises in Nairobi County. The study was based on Kram’s mentor role theory that says mentoring can be classified into dual functions: Psychosocial support and Career development. The research design adopted was correlational in nature. From the findings, it was established that one on one or traditional mentoring and virtual mentoring were statistically significant in influencing performance of youth entrepreneurs in Nairobi County. Therefore, the study suggests for greater focus on these two mentoring programs by improving entrepreneur awareness of the existence and efficacy of these mentoring programs, creating and improving existing access channels and support for participants at a county level, and tailoring policy towards anchoring sound youth entrepreneurial mentoring using one on one and virtual mentoring programs.
