GiveWell is a non-profit organization that aims to identify the most effective charities and make it easy for donors to give to them. The organization conducts in-depth research on a variety of charities, evaluating them based on factors such as the impact of their programs, their cost-effectiveness, and their transparency and accountability. GiveWell then publishes its findings on its website, where it recommends a small number of charities that it believes are the most effective at improving the lives of people in need. The recommended charities are typically those working in global health and development, specifically those that focus on providing cash transfers, malaria control, and providing access to clean water, sanitation and hygiene. GiveWell is supported by donations from individuals and foundations, and does not accept donations from charities it evaluates.
