Key takeaways

  • The Tang Fund is a New York-based foundation with no stated geographic focus, though its grants have mainly gone to New York.
  • It funds a broad range of organisations including cultural institutions, schools and universities, museums, food-access groups, environmental organisations, animal-welfare groups and libraries, with grant purposes recorded simply as charitable; it also carries out direct work on diversity and racism awareness.
  • Annual giving has risen sharply to $17,935,511, but most grants are modest: about 8 in 10 of its 238 grants fall between $500 and $200,000, the median is $5,000, and half of all grants were $5,000 or less, so a request in that range is realistic even though one grant reached $10,000,000.
  • The fund is highly relationship-led: 98% of its grant dollars went to organisations it had already funded in the prior two years, and it operates by invitation only, so unsolicited applications should not be sent.
