Key takeaways

  • If your organisation works on housing justice and homelessness, harm reduction and substance use, mental health and wellness, or community healing in Mendocino, San Diego or Oregon, the foundation's stated focus fits you.
  • Half of its grants to organisations are $10,000 or less, so a request towards the lower end of its typical band of $10,000 to $200,000 is realistic; that band is not a limit, as its largest grant was about $755,000.
  • GO Grants are regionally restricted, so check that your region is covered and join the email list to hear when the GO Grant application is released.
  • The foundation emphasises relationships, lived experience and boards and staff that reflect the communities they serve, so a personal introduction and a clear account of these will help, and 35% of its grant dollars went to organisations it had already funded, so building on any existing link is worthwhile.
  • Applications are kept brief and reporting is usually a coffee date with a team member.
