Cornerstone Foundation

• Cornerstone Foundation states that it does not accept unsolicited requests, so approach it only if you can secure an invitation before sending anything.
• Its funding covers environmental protection, education and literacy, services for women and children, reproductive health, civic participation and justice, college access, LGBTQ+ support and basic needs, so check that your work sits within one of these.
• Most of its grants fall between $55,000 and $325,000, with a median of $150,000, so a request in that region matches its usual pattern; the largest grant was $350,000, so that band is not a ceiling.
• In its most recent filing, 75% of grant dollars to organisations went to groups it had also funded in earlier filings, which suggests that existing relationships carry weight.
• No geographic focus is stated, so location does not by itself decide eligibility, although the filing shows grants mainly in District of Columbia, New York, Maine, Pennsylvania and Maryland.
