## About

The Rockefeller Brothers Fund was established in 1940 by the five third-generation Rockefeller brothers. Its endowment originated from the family's Standard Oil fortune. The foundation operates from New York with the Pocantico Center in Sleepy Hollow serving as an additional venue for convenings. The fund allocates across private equity, venture capital, and public equities with an ESG overlay. Confirmed positions include commitments to ARCH Venture Fund IX Overage in 2017, Blue Bear Capital Fund II in 2021, and Blue Bear Capital Fund III in 2024. It also participated in a 2016 consortium investment in Mainstream Renewable Power Africa Holdings alongside IFC and Ascension Investment Management. Geographic reach covers Africa, Asia, Europe, North America, and South America. The strategy favors fund commitments and direct co-investments that generate market-rate returns while advancing measurable social or environmental outcomes. The endowment stands at 1419 million USD. The firm employs 78 professionals. In 2024 the fund committed to Upstart Co-Lab's Inclusive Creative Economy Strategy as one of 26 investors. It maintains the Pocantico Center properties including Kykuit and the David Rockefeller Creative Arts Center. The fund outsources investment management to an OCIO platform. The fund's structure integrates grantmaking with endowment deployment under a single mission-aligned mandate. This allows direct linkage between programmatic priorities in climate and democracy and capital allocation decisions, including a 2014 fossil fuel divestment that preceded targeted reinvestment in renewables and climate technology.
