Impact Investing: The Practical Guide provides a beginner's guide for those new to impact investing by explaining the fundamentals and as a reference for practitioners already further along who may benefit from the more technical components of deal structuring. While plenty of books exist on impact investing, this book intends to be a practical guide for those looking for actionable strategies and advice. It leverages the lessons from an insider's decade of experience across multiple asset classes (debt, equity, and grants) at two major foundations. It covers both direct investments as well as fund investments and their respective critical factors to consider. Whether you are an entrepreneur or a seasoned professional at a foundation, a family office, an investment fund, a corporate investment arm, or a nonprofit, this book provides tips that can help you understand the various stakeholders involved. The book also offers several case study examples of impact investments to demonstrate key concepts, including the structuring and application of catalytic capital to drive impact.
