What Rockefeller Brothers Fund Inc does
Programs
The pocantico center campus, housed on the grounds of the pocantico historic area, is managed by the rockefeller brothers fund as part of its agreement with the national trust for historic preservation, entered into in 1991, under which the fund is responsible for the renovation, maintenance, and operation of this historic site. The campus serves as a community resource for all ages, and offers public access through a slate of conferences, artist residencies, a visitation program, a museum, performances, permanent exhibitions, educational programs, and an annual family-focused community day. During 2024, 71 public programs were held. The pocantico center welcomed more guests than ever in 2024, including visits for public programs, the visitation program, conferences and meetings, artist residencies, and largely due to the new capacity provided by the david rockefeller creative arts center (see statement 22, statement 24 and statement 29).
$10,790,720 spentThe david rockefeller creative arts center opened in fall of 2022 following a construction project centered around the reuse of the orangerie, built by john d. Rockefeller in 1908 on the historic rockefeller family estate and bequeathed to the national trust for historic preservation in 1979 by nelson rockefeller, which transformed the long-dormant building into this new space. Additional day-two construction work continued in 2024. The david rockefeller creative arts center is a sustainable and inclusive home for the creative process at the pocantico center, where artists and the community come together to develop, present, and experience new works of performing, literary, and visual arts. The center includes a gallery, performance space, and a flexible artists' studio. The pocantico prize for visual artists commenced in 2022 and pairs a cash prize with a two-month residency at the david rockefeller creative arts center. See statement 29.
$2,820,313 spentDuring 2024, 11 members of the staff of rockefeller brothers fund provided technical assistance to charitable organizations, governmental bodies and committees, and 22 members of the staff served on 66 charitable organizations' boards, committees, public commissions, or task forces.rockefeller brothers fund's website provides additional details on the fund's charitable activites: https://www.rbf.org including www.rbf.org/about/transparency/annual-reviews for its annual review.
$815,120 spentThe pocantico center of the rockefeller brothers fund, located within the pocantico historic area (see line 1, above), began operations in april of 1994. The pocantico center is a venue for conferences and meetings that meet various criteria including direct and strong relationship to the fund's program objectives, and display of diversity of perspectives, range of opinions and breadth of experience. The pocantico center also hosts artist residencies for performing, visual, and literary artists selected by the fund's grantee organizations based in new york city. These residencies support the creative process, advance cultural awareness, and foster artistic collaborations by creating time and space for aesthetic exploration and nurturing artistic imagination. Artists-in-residence stay in the residential buildings at pocantico. The pocantico center held 56 conferences and meetings and 13 artists' residencies in 2024. See statement 29.

The organization over time
Each line starts at 100 in 2020, so what you read is the shape rather than the size: 150 means half as much again as 2020, 50 means half. The number beside each label in the key is where it ended. The shaded band is where the middle 50% of its peers' revenue would sit, given their growth.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2021 to 2022, from $1.7B to $1.4B (−18%).
Leadership and staff
The officers, directors, trustees and key employees listed on each return. Joined and no longer listed compare each filing with the year before, matching people by surname and first initial; a year after a gap, or a roster under three people, has no comparison.

Who funds it, year by year
2017 → 2023: the base broadened from 1 funder to 3 funders, grant income rose $600k → $3.9M.
1 of 8 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 0% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.
Left out of every figure on this page: $645k from 2 payers (the payer shares this organization's board, largest Rockefeller Philanthropy Advisors Inc). These are real filings, and they are not money ROCKEFELLER BROTHERS FUND INC raised.
From the IRS filings of ROCKEFELLER BROTHERS FUND INC’s funders (the co-funder graph). Association, not causation. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
How concentrated its funding is
ROCKEFELLER BROTHERS FUND INC leans on a few funders — its largest provides 54% of grant income and the top three 94%; half comes from just 1 funder.
the vertical line marks half of all grant income — 1 funder to its left
40% of the income these shares are computed over arrives through pass-through sponsors or from payers whose filings do not say what kind of payment it is. Concentration is still measured over all of it, because the money is real; what it does not support is a claim about how many institutions have chosen to fund ROCKEFELLER BROTHERS FUND INC.
Largest funder’s share by year: 2017 100% · 2018 71% · 2019 59% · 2020 65% · 2021 82% · 2022 78% · 2023 96% — diversifying over time.
“Effective funders” = inverse Herfindahl index (1 / Σ shareᵢ²) — the number of equal-sized funders that would give the same concentration. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
How long its funders stay
40% of ROCKEFELLER BROTHERS FUND INC's funders are still giving 3 years after their first grant; 75% give in more than one year at all.
Share of funders still giving k years after their first recorded grant, pooled across every acquisition cohort. A funder counts as retained in a year only if it made a grant that year. Measured to FY2023, the last fiscal year that has finished arriving — a funder cannot be counted as lapsed in a year most filers have not reached.
Where its funders are
ROCKEFELLER BROTHERS FUND INC draws 94% of its grant income from funders outside New York, across 3 states in all.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $20k arriving through sponsors registered in 1 state is excluded from the map and the split above: a sponsor holds money on a donor’s behalf, so its registered address would place those dollars somewhere no donor need ever have been. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
