William and Flora Hewlett Foundation
At a glance
Key takeaways
- Before approaching the foundation, check that your work fits one of its stated themes, such as Education, Environment or Performing Arts, and that your area appears in its geographic focus, which the filing lists as Priority: Bay Area; Globally; U.S. West; East and West Africa; Mexico; U.S.; Europe; China; India.
- Most grants go to organisations the foundation identifies itself, and 88% of its grant dollars to organisations went to groups it had also funded in the two previous filings, so it looks relationship-led and a cold request is unlikely to be the main route in.
- Half of its grants to organisations were $150,000 or less, so a request of that order is a realistic starting point, though its typical range of $5,000 to $580,000 describes what most grants fall between rather than a limit.
- It generally does not accept unsolicited letters of inquiry, so watch for invitations through its open processes, which it publicises through email updates and LinkedIn, and note that it prefers long-term, general operating support whenever possible.
- It does not fund individuals, scholarships, unincorporated associations or groups, or political candidates and political action committees, so organisations of those kinds should not apply.
