GiveWell and Open Philanthropy are sister organizations in the effective altruism community. Both seek to identify outstanding giving opportunities, but they use different criteria and processes.

​

GiveWell has an emphasis on evidence-backed organizations within the global health and wellbeing space, while Open Philanthropy also supports high-risk, high-reward work, as well as work that could take a long time to pay off, in a variety of cause areas. We think this illustrates interesting methodological differences between attempts to answer the question “How can we do the most good?”.
