Key takeaways

  • The Thirteen Foundation, based in Cisco, TX, says it makes contributions only to organisations it has preselected and does not accept unsolicited requests, so a cold application is unlikely to be considered.
  • Its filing describes it as set up to fund right-wing causes, so only work that clearly fits that description is worth raising with it.
  • The filing reports $3,655,865 paid in total giving but states no grant range and no typical grant size, so any request should be sized to your own budget rather than an assumed figure.
  • Because it is invitation-only, the only realistic route is an existing connection to the foundation, and there is no published timetable or open call to plan around.
  • Small charities whose work falls outside right-wing causes, or who cannot reach the foundation through a contact, should look to other funders.

Priority Areas

The Thirteen Foundation is described as a charity created by Farris Wilks and his wife to fund right-wing causes. In its filings, it says it makes contributions only to preselected charitable organisations and does not accept unsolicited requests. The e-filed grant rows name no recipients, referring instead to attached schedules of donees, and describe the purposes only as various; they therefore do not establish particular recipient types or more specific fields of support. The foundation also reports direct charitable activity through its wholly owned disregarded entity, Reach for Yahweh International.
