| Welcome to our December 2025 newsletter — our first as Coefficient Giving!
In case you missed it: As of last month, Open Philanthropy is officially Coefficient Giving, a name that better reflects our role as a philanthropic funder and advisor working with many donors.
Read about how we chose our new name here. For more on our future plans, read this essay by our CEO and co-founder Alexander Berger.
We are continuing to grow our team: see here or the end of the newsletter for open roles and opportunities to get involved. And keep reading for more updates and highlights from the past month!

| | | | In addition to launching Coefficient Giving, we: More than doubled the size of our Abundance & Growth team — welcome to Alex, Dylan, and Willow! Published new explainers on concepts essential to our grantmaking: worldview diversification, hits-based giving, and strategic cause selection. Published a shallow investigation on hepatitis D (produced by Douglas Chukwu Junior of the Global Health & Wellbeing Cause Prioritization team). Our goals were to estimate the attributable disease burden, learn more about barriers to addressing it, and identify potential funding opportunities. Opened a request for proposals for projects that use AI to improve probabilistic forecasting and support sound decision-making. Published a guide that explains our process and underlying framework for drafting back-of-the-envelope calculations (BOTECs).
