This lecture from Yale's Creating Change through Social Entrepreneurship course explores approaches social entrepreneurs can use to expand impact beyond the direct services their own venture provides. The instructor presents nine distinct strategies, such as open-sourcing a model, training other organizations, shaping policy, or building coalitions, and explains when each approach fits a venture's stage and resources. The lecture frames impact expansion as a deliberate strategic choice rather than an afterthought, encouraging founders to think about how their work can influence a field even if their own organization cannot scale to meet every need. It draws on examples from established social enterprises to illustrate each expansion path. The session closes out the course's unit on sustaining and multiplying impact after a venture's initial model is proven.
