Information for Donors Referred From the Effective Altruism Foundation, Which Runs the Raising for Effective Giving Program

The Effective Altruism Foundation (EAF) is a Switzerland-based non-profit think tank and project launching hub for rationality, applied ethics, and science. EAF runs the Raising for Effective Giving (REG) program, among others.

GiveWell (a.k.a. The Clear Fund) is a federally-recognized tax-exempt 501(c)(3) organization. US donors are able to take tax deductions for donations to GiveWell to the extent permitted by US tax laws.

Donors can give to GiveWell and specify how they prefer GiveWell to designate their gift (for the support of EAF, for the support of one of GiveWell's recommended charities, or for GiveWell's operations). Please note that donations to GiveWell are irrevocable and donor requests to grant donations to our recommended charities (or EAF) are subject to our approval (more details on GiveWell's approval process here). GiveWell collects no fees from such donations.

We will share donors' names and contact information with EAF.
