Overview

The Thirteen Foundation was established in 2011 by Farris and JoAnn Wilks following the sale of their fracking company for $3.5 billion. The foundation manages approximately $45.6 million in assets and operates as a private grantmaking foundation focused on religious conservative causes. In 2011, Farris and JoAnn each contributed $50 million to establish the foundation. The foundation has been described as "one of the biggest and quietest anti-abortion donors in the United States" and operates with minimal public profile, though tax filings are publicly available. The foundation operates through a wholly owned disregarded entity called Reach for Yahweh International, established as a Missouri limited liability company.
