This website is a knowledge centre on strategies and methods for evaluating impact investing. Whether you are an investor, investee, researcher or policymaker, there are links to a rich array of reports and tools here that you can use to develop or improve your social impact measurement system.


We are proud to curate this site. We’ve had the privilege of working in the field of impact investing and in development evaluation for many years in all parts of the world. We believe that all forms of innovative development finance, including impact investing, should be held to account for their claims of social, economic or environmental impact. Further, it is our experience that evaluation, monitoring and other types of performance assessment can play an important role in organizational learning, improvement and innovation, as well as in accountability.
