Open Philanthropy was originally incubated as a partnership between Cari and Dustin’s foundation, Good Ventures, and GiveWell.
GiveWell was founded in 2007 by Elie Hassenfeld and Holden Karnofsky, who had been trying to donate as effectively as possible. They aimed to help people facing a similar situation to their own: interested in giving to charity, short on time for researching their options, and looking for highly evidence-backed charities to support.
Good Ventures was founded in 2011 by Cari Tuna and Dustin Moskovitz. They were looking to give their fortune away in their lifetimes, and as effectively as possible, in order to help humanity thrive. Cari took the role of President, and spent her first year speaking with a broad range of people in search of advice.
The two organizations found that they shared a great deal in terms of their vision and values, and came to collaborate closely. The partnership adopted the Open Philanthropy Project name in 2014, and began operating independently in 2017.
