Giving Multiplier is a website that adds 3% to 30% on top of donations to any charity on condition that donors give a percentage (at least 10%) to an effective charity from their list of expert recommendations. It was created by the psychologists Lucius Caviola and Joshua Greene at Harvard University based on their research[1] and is funded by Effective Altruism Funds.
