The WCS Entrepreneur Circle (E-Circle) is a three-month cohort program designed for entrepreneurs who identify as women to communicate, reflect, and connect with each other. More than a mentorship program, the E-Circle offers you opportunities to commune with up to 11 fellow entrepreneurs, build relationships with leaders in this space, and collect new resources. In monthly virtual meetings and in Slack, the group will learn from a keynote speaker, share advice, challenges, and offer support. The program is initiated and organized by WCS Entrepreneurship Committee.
