The Tommy Fuss Fund
At a glance
This funder does not accept unsolicited applications. The foundation chooses the organisations it funds itself.
Key takeaways
- The Tommy Fuss Fund's stated focus is medical and psychiatric research on mental illness, with a focus on adolescents, so a service-delivery project would sit outside it.
- The foundation does not accept unsolicited requests and makes contributions only to preselected organisations, so a cold approach is not the route in; an organisation should wait for an invitation rather than send an application.
- Typical grants fall mostly between $150,000 and $640,000, with a median of $250,000, so a request near the lower end of that band fits its usual pattern, though the largest grant was about $1,200,000, so the band is not a ceiling.
- Repeat recipients received 43% of grant dollars to organisations, so an ongoing relationship matters, and the filings show grants mainly in Massachusetts, although no geographic focus is stated.
