Key takeaways

  • The Peterffy Foundation funds environmental and educational causes, working through the Living Forest Project, One Small Planet and Reweaving the Web, and its recorded purposes include support for Indigenous organisations in the Brazilian Amazon and national forest protection, so only work that fits these themes is worth pursuing.
  • Most grants to organisations fall between $10,000 and $250,000, with a median of $50,000, and half of its grants were $50,000 or less, so a modest request in that range is realistic.
  • The foundation states it does not accept unsolicited requests and operates by invitation only, so a cold application should not be sent; approach is only likely to work through an existing connection.
  • With 86% of its grant dollars going to organisations it had also funded before, it looks relationship-led and favours continuing support over new applicants, so it is a hard target for a first approach.
  • No geographic focus is stated, so location on its own should not be assumed to rule an organisation in or out.
