Pathfinder / funder / opportunities / Open Philanthropy
Open Philanthropy is a grantmaking organization focused on high-impact philanthropy. It was founded by Cari Tuna and Dustin Moskovitz; public 990 filings identify it as a private foundation–style philanthropic entity rather than a fundraising startup. No public evidence of a current raise target was found.
Open Philanthropy's 2023 990 filing shows $4.9M in functional expenses and appears in our system as a peer-funder enrichment context rather than a grantable organization. The composite score of 18/100 reflects zero thesis fit, zero talent density, and zero founder credential signals because this is a funder entity, not a fundable project. The 0.4 peer-funder-signal component confirms this record exists to help us understand the philanthropic landscape, not to evaluate as a deal opportunity.
