Unsolicited applications are not accepted

This funder does not accept unsolicited applications. The foundation chooses the organisations it funds itself.

Key takeaways

Pine Rock Foundation says on its website that it does not accept unsolicited requests, so an organisation that has not been invited should not send it an application.
Its grant-registration form asks for a referrer, so any approach should be made through someone who can refer the organisation.
Its recorded grants cover education, journalism and civic or policy work, arts and culture, conservation and wildlife, faith, health and disability services, and community safety, and no geographic focus is stated, though the filings show grants mainly in Minnesota, Montana, Florida and Wisconsin.
About 8 in 10 of its 93 grants to organisations fall between $5,000 and $300,000, the median is $25,000 and half are $25,000 or less, so a request near that figure sits within its typical range, although its largest grant was $3,000,000.
Repeat recipients received 92% of its grant dollars to organisations, so the foundation appears relationship-led and a first approach may take time to lead to a grant.

Overview

Pine Rock Foundation is a US private foundation based in Sioux Falls, SD.

What they fund

Profile derived from the foundation's IRS Form 990-PF filings (TY2025, TY2023, TY2022) and its website, with every statement checked against those sources. Sources read on 7 October 2026.

Priority Areas

The foundation's recorded grants span education, including schools and education organisations; journalism and civic or policy work; arts and cultural organisations; conservation and wildlife; faith organisations; health and disability services; and community safety. Its support has included both general or unrestricted operating support and designated programmes, alongside capital works, equipment, exhibitions, environmental projects and specific service costs. Its recipient record therefore covers several distinct kinds of charitable organisation and activity, rather than a single stated subject area. The records show recipients in several states but do not set out a geographic eligibility rule.

Geographic Focus

No geographic focus is stated; the filings show grants mainly in Minnesota, Montana, Florida and Wisconsin.

How to apply

The website provides a grant-registration form. It asks for the amount requested, a referrer, the purpose or designation of funds and proof of 501(c)(3) status. The site says unsolicited requests are not accepted.

Application success factors

Repeat giving: In its TY2025 filing, 92% of its grant dollars to organisations went to organisations it had also funded in its TY2022 or TY2023 filing.
Grant size: Across its TY2022, TY2023 and TY2025 filings, half of its 93 grants to organisations were $25,000 or less.
