Giving Multiplier was created by Dr Lucius Caviola and Prof Joshua Greene. We are researchers in the Department of Psychology at Harvard University. Our research examines the factors that influence charitable giving, with the goal of helping people make wiser charitable giving decisions.

Matt Coleman (matt@givingmultiplier.org) is Project Manager responsible for growth of the platform and the website is developed by Fabio Kuhn.

See our Frequently Asked Questions to learn more about Giving Multiplier. And for questions or feedback, please contact us at info@givingmultiplier.org.
