Zeldin Family Foundation is a $6.34M private foundation headquartered at 2039 Delancey Place in Philadelphia, PA, with IRS tax-exempt status since July 1987 (EIN 23-6861835). It is one of the longer-established small family foundations in the Philadelphia area and operates without a public website application portal — the published zeldinfamilyfoundation.org site is a minimal landing page built on Wix. According to Instrumentl 990 profile, the foundation grantmaking focuses on Education, Philanthropy/Voluntarism & Grantmaking, and Human Services — primarily in Pennsylvania, New York, and Massachusetts. Cause IQ describes the funding pattern as "charitable operating expenses and grants," and Grant Bay cumulative history counts 450 grants totaling $2,686,182 going to Texas, DC, and 12 other states plus international recipients. The strategic posture is a traditional multi-generational family foundation: high grant count, very low median grant size, and a broad geographic reach anchored in the Northeast corridor.
Zeldin Family Foundation most recent fiscal year (ending December 2024) reports $801,381 in revenue, $585,659 in expenses, and $6,341,492 in total assets per ProPublica. Instrumentl reading of the 2024 990-PF puts total grant dollars at $560,750. Cause IQ reports 88 grants in the most recent filing year, which implies a median grant size near $1K and a weighted-average around $6.4K — a very high-volume, small-dollar pattern. Grant Bay cumulative analysis across all available filings (450 grants for $2.69M total) confirms the same structural signal: this is not a foundation that writes $50K–$100K anchor grants; it is a foundation that sprays $1K–$10K grants across a broad set of mostly Northeast cultural, educational, and human-services organizations. One known grantee cited in search results is Arden Theatre (Philadelphia), which tracks with a PA-centric arts/education tilt. Giving has been roughly stable from 2019 ($414K) through 2024 ($586K), with no dramatic expansion or retrenchment.
| Foundation | City/State | Assets | Annual Giving | Grants/Yr | Median Grant |
|---|---|---|---|---|---|
| Zeldin Family Foundation | Philadelphia, PA | $6.34M | ~$561K | 88 | ~$1K |
| Fenwick Foundation | Pennington, NJ | $6.36M | ~$940K | ~75 | ~$12K |
| Margolis Family Foundation | Corona Del Mar, CA | $5.58M | ~$711K | 26 | ~$10K |
| Dry Creek Charity | Holladay, UT | $5.71M | ~$241K (2024) | 15–16 | ~$7.9K |
| Pfeiffer Family Foundation | Aberdeen, SD | $5.91M | ~$209K | small (new filer) | n/a |
Zeldin stands out in this peer cohort for writing the most grants per year (88) at the smallest median size (~$1K). That inverted pattern matters a lot for applicants: if you need $10K+, you are asking for roughly 10x the median award and will be an outlier. If you can accept a $1K–$2K sponsorship-style grant, you fit the modal pattern perfectly.
The most recent IRS-digitized filing is fiscal year ending December 2024 (published on ProPublica in mid-2025). Revenue was $801,381, expenses $585,659, assets $6,341,492 — all three up from 2023 ($438,884 / $433,638 / $6,125,770), indicating a modest uptick in both corpus and distributions. Instrumentl cites $560,750 in 2024 grants, consistent with ProPublica expense total after administrative costs. No public announcements of new strategic priorities, new trustees, staff hires, or open RFPs were identified via search as of April 2026 — the foundation continues to operate as a trustee-directed family vehicle. Cause IQ last refreshed data on 2024-12-01. Candid Foundation Directory last updated the Zeldin profile on 2024-07-25. The next 990-PF (FY2025) will likely publish to ProPublica in mid-to-late 2026.
1) Match your ask to the foundation grant-size distribution: a $1K–$5K request with a clearly defined use (program sponsorship, event underwriting, small capacity grant) dramatically outperforms a $25K general-operating ask for a foundation with a ~$1K median grant. 2) Geographic fit matters — prioritize organizations operating in Pennsylvania, New York, and Massachusetts per Instrumentl categorization. 3) The foundation does not publish an open application portal; a short, personalized letter of inquiry mailed to the 2039 Delancey Place address is the correct first step. 4) Use Grant Bay 990-PF grant history (https://grantbay.org/form-990/236861835) to identify grantees in your peer network — a prior grantee introduction raises response odds materially. 5) Education, arts/culture (Arden Theatre is a known grantee), and human-services organizations have the strongest category fit; scientific research and large-scale infrastructure requests do not match the foundation profile. 6) Budget a 6–9 month timeline from inquiry to decision and do not expect automatic acknowledgment.
