Context: The blended learning (or b-learning), has grown over the years. However, few studies have been carried out on the effectiveness of entrepreneurial training in the blended modality. Objective: The general objective of the study is to evaluate the effectiveness of the learning experience in the blended modality experienced by adults for the development of entrepreneurial skills. Method: This work conducted a Digital Ethnography study by combining qualitative research techniques to capture the evidence of the participants' perceptions in the blended modality. The survey was conducted with adult entrepreneurs. Results: At the end of the study, it was possible to identify aspects of improvements in the usability of the platform, reflections on the teaching process, identification of points that reinforce the positive experience for the participants and a reduction in dropout from 40% of face-to-face education to 6.67% (1st class) and 4.35% (2nd class), and 0% (3rd class) in blended education. Conclusions: If proper engagement mechanisms are used, blended learning is an effective and efficient educational instrument for adult entrepreneurs, which usually have busy daily routines and need flexibility in their study schedule.
