I read Toniic's new eGuide to Early Stage Impact Investing yesterday and was happy to see that it is full of helpful and specific information about how to do this very important work. In contrast to some impact investing guides which operate at an more poetic level, this guide is really wired to answer very concrete questions and describes a clear process from theory of change to evaluation.

It focuses on early stage investing, but the framework is applicable to all impact investing.
