Key takeaways

  • The Mayer Family Foundation is based in Greenwich, CT, and the filing says it makes contributions only to preselected charitable organisations.
  • It does not accept unsolicited requests, so a small charity should not send a cold application, and the filing describes no public route onto its list.
  • The filing shows $367,729 paid out in the latest year, against a typical year of about $805,000, but it gives no grant range and does not say which organisations received support, so no realistic request size can be set from it.
  • Because no geographic focus or fields of work are stated, do not assume your area or cause fits; any existing contact with the foundation or its trustees is the only route the filing suggests.

Priority Areas

The Mayer Family Foundation makes contributions to preselected charitable organisations and does not accept unsolicited requests. Its disclosed grant entries describe the support as general support, but do not identify the recipients. The available information does not name causes, types of organisation beyond charitable organisations, or a geographic focus. It establishes a preselected approach to giving, rather than a public application route, and provides no basis for describing particular fields, beneficiary communities or geographic priorities. Its giving record does not show which organisations received the listed support.

How to apply

Contributions are limited to preselected charitable organisations; the foundation does not accept unsolicited requests.
