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

Key takeaways

  • The foundation states that it does not accept unsolicited requests and works by invitation only, so a cold application is unlikely to be considered; the realistic first step is an introduction through an existing connection.
  • If an invitation comes, its typical grants run from $2,500 to $75,000, with about 8 in 10 of its 32 grants to organisations in that range and a median of $20,000, so a request near that size fits its record.
  • Most of its grant dollars, 88% in the latest filing, went to organisations it had also funded in the two earlier filings, so a new organisation should not expect a quick or easy route.
  • Its grants cover general support, a transportation programme, re-entry support, health and medical research and community-service work; no geographic focus is stated, though the filing shows grants mainly in Massachusetts and New York, so judge fit by its grant record rather than a stated field.
  • Organisations that need to apply on their own initiative, without an invitation, should look elsewhere.

Overview

Six String Giving Foundation is a US private foundation based in Wilmington, DE.

What they fund

Profile based on the foundation's IRS Form 990-PF filings (TY2024, TY2023, TY2022) only: no website or other web source for the foundation was found. Every statement is checked against the filings. Sources read on 7 October 2026.

Priority Areas

The grant record is dominated by general and unrestricted support, alongside grants for a transportation programme, re-entry support, and health and medical research. Recipients include a charitable gift fund, a university, community-service organisations and health-related charities. The foundation also reports a direct activity addressing food insecurity through volunteer-staffed food markets for residents in low-income communities. The record therefore shows support reaching a range of charitable organisations and activities rather than a stated field of grantmaking or a public application programme.

Geographic Focus

No geographic focus is stated; the filings show grants mainly in Massachusetts and New York.

How to apply

The foundation states that it does not accept unsolicited requests.
