Key takeaways

  • The foundation organises its giving around STEM education, environmental protection in Texas and across the U.S., and women's empowerment and equal opportunity, so a small charity should approach it only if its work clearly sits in one of these areas.
  • Other published sources say it does not accept unsolicited requests and gives by invitation only, so a cold application is unlikely to be considered and an existing relationship is the realistic route in.
  • Its typical grants fall between $4,550 and $450,000 for about 8 in 10 grants, with a median of $75,000, so a modest request in that band is sensible, though that band is not a ceiling because its largest grant was about $610,000.
  • Repeat funding is strong, with 54% of its grant dollars to organisations going to groups it had already funded in earlier filings, so a newcomer should expect to compete with established grantees.
