In this Yale interview from Creating Change through Social Entrepreneurship, Sally Abi Khalil discusses how social entrepreneurs can expand their impact through policy work and advocacy rather than through their individual ventures alone. Drawing on her own experience in advocacy-focused roles, she explains how engaging with policymakers and public institutions can multiply the reach of a social mission beyond what a single organization could achieve through direct service. The conversation covers the practical realities of advocacy work, including building coalitions and communicating evidence to decision-makers. Students hear a firsthand perspective on policy as an impact-expansion strategy, connecting to the course's broader unit on the many ways ventures can extend their influence on a field or issue.
