Key takeaways

  • The Cullen Foundation funds education, healthcare, public service and cultural arts work in Texas, with priority given to the Greater Houston area, so fit matters most if your work sits in one of those themes and that geography.
  • Typical grants to organisations run from $60,000 to $1,000,000, with a median of $175,000, so a request in that band is realistic, though the largest grant made was $6,000,000.
  • Around 60% of grant dollars went to organisations it had already funded in the two preceding filings, so this looks like a relationship-led funder where sustained contact matters; a first approach should be a Letter of Intent, since this is treated as an inquiry rather than an application, with a full application only following an invitation.
  • Applications are reviewed on a rolling basis, and any specific deadline is given only once an organisation is invited.
  • Businesses and individuals are not funded, so neither should approach the foundation; others considering a request should bear in mind its stated preference against general operating support, fund-raising events such as galas, organisations that themselves re-grant to others, activities solely promoting a specific religion or denomination, and purchases of uniforms, equipment or trips for school-related or amateur sports groups.

How to apply

Organisations without an invitation may submit a Letter of Intent aligned with the Foundation’s mission; this is an inquiry, not an application.

The Board reviews applications on a rolling basis, and invited applicants are given any specific deadline.

  • Grant size: Across its TY2022, TY2023 and TY2024 filings, half of its 104 grants to organisations were $175,000 or less.
