The document discusses and compares business models and impact models. A business model focuses on creating, delivering, and capturing value for profit, while an impact model prioritizes creating, delivering, scaling, sustaining and measuring social and environmental impact. The document argues that an impact model, which considers people, planet and profit, is needed to address today's social and environmental crises and regain public trust in business. An impact model framework called the "Impact Model Canvas" is introduced to help organizations design impactful business propositions.
