GiveWell is an American charity evaluator. GiveWell was founded in 2007 by Holden Karnofsky and Elie Hassenfeld, who aimed to rigorously assess the effectiveness of non-profits with the techniques they used while working at a hedge fund. They received early funding from the William and Flora Hewlett Foundation's Nonprofit Marketplace Initiative. GiveWell later partnered with Good Ventures to establish Open Philanthropy (since renamed Coefficient Giving). GiveWell has said that it has guided the donations of 150,000 donors and moved $2.6 billion to their recommended organizations. Under their cost-effectiveness estimates, this has averted 340,000 deaths.
