We do not recommend adding participants after Session 2. Sessions 1 & 2 set the foundation for the cohort experience. Session 1 is time for the business owner to self reflect about themselves in their role as an entrepreneur and connect with the cohort; Session 2 begins to explore who their customers are and what are their needs.  Because the cohort session allows for six hours of discussion framing these areas plus fieldwork, missing this important content does not set a participant up for success, rather they begin already behind.
