This Yale lecture from Creating Change through Social Entrepreneurship distills practical do's and don'ts for pitching and communicating a social venture effectively. The instructor highlights common mistakes founders make when presenting their work, such as burying the impact story under operational detail or failing to tailor the message to the listener, and contrasts these with techniques that make a pitch memorable and persuasive. The session builds on earlier lessons about pitch structure and communications planning, consolidating them into a checklist-style review that students can apply directly to their own ventures. It is aimed at social entrepreneurs preparing to present their ideas to funders, partners, or the public, and closes out the course's unit on effective outreach and storytelling for mission-driven organizations.
