Ideal Applicant
Mid-to-large nonprofit or research institution aligned with the foundation's priorities (tauopathy/medical research, education and college advising, family economic security, community development) with demonstrated impact and capacity to manage sizable grants, especially organizations operating in Fort Worth/Texas.
Good Fit
- • Programs focused on tauopathy research or medical research with institutional capacity.
- • Education initiatives such as college advising, leadership academies, or district partnerships.
- • Community development work in Fort Worth/Tarrant County or broader Texas impact.
- • Organizational track record for operating or capital-scale grants and rigorous reporting.
- • Ability to engage through the grantee portal and respond to LOI windows (April and October).
- • Introductions or relationships with local intermediaries or foundation staff.
Geography
Latest-year grants reached 21 states, but about two-thirds of dollars were concentrated in Texas, indicating statewide focus with some national grants.
Recipient Variety
The foundation funded 201 distinct organizations in 2024 (295 grants) and added roughly 110 new recipients that year, showing a broad and diverse recipient set rather than a tiny closed circle.
New Applicants
Direct evidence of recurrent open competitions is limited because the foundation states funding is by invitation, but the site provides a grantee portal and LOI cycles and the latest year shows many first-time grantees, so new entrants can access funding though selection appears curated.
