This course offers an introduction to social impact strategy and social entrepreneurship, including key concepts, an overview of the field, and tools to get started as a changemaker. Students will learn how to innovate and design new ideas and new organizational forms to implement those ideas. Students who take this course will be better prepared to launch social impact organizations of their own invention. By moving through four stages, Define, Design, Pilot, and Scale, students will turn their passion for changing the world into concrete plans for launching a nonprofit or for-profit venture designed to achieve a social goal. This course will allow students to systematically think through problems; develop and test an innovative solution; assess risk, competition, and performance; and spread impact in a way that is financially sustainable. Students who complete the course become eligible to apply for an in-person educational experience, called the Global Social Impact House. GSIH is a seven-day residential program that provides fellows with the tools, community and training they need to advance their ventures. Workshops are customized to the needs of fellows and explore advanced concepts in business models, design thinking and leadership. The program is also designed to help fellows build meaningful, global connections while living together in an inspirational host location.
