Grantmakers In Health's (GIH) Guide to Impact Investing offers a framework to help funders think strategically about the potential of impact investing and move forward with investment strategies
that can enhance achievement of their missions. The guide provides an overview of the spectrum of various impact investment types, and presents case studies of foundation investments. It explores the strategic benefits and added impact of these strategies, and the challenges funders have encountered along the way. The guide also includes how-tos and practical information for funders wanting to get started.

This report is grounded in the view that foundation resources are scarce relative to both philanthropy's aims and society's needs. Effective philanthropy, therefore, leverages resources as fully as possible, combining convening, networking, communications, and policy initiatives with grantmaking to drive social change. As a set of tools, impact investment strategies offer funders tremendous power to shape, accelerate, and scale desired results.
