🎉 Giving Multiplier turns 5!
We launched in 2020 as a proof of concept — could we apply behavioral science to help people increase their charitable impact?
“We would have been happy if we raised a little bit
better than bake sale," said co-founder Prof. Joshua Greene (@MoralityLab).
Five years later, we're celebrating $5 million in donations from 5,000 donors, supporting some of the world’s most cost-effective charities addressing global health, climate change, and much more.
Thank you!
