Key takeaways

  • Allen Family Philanthropies funds arts and culture, youth and environment, with a geographic focus of Pacific Northwest as a priority, then U.S., internationally, and Washington state, so grant writers should check their work sits within these themes and areas.
  • Typical grants run from $815 to $885,000, with about eight in ten of its grants falling in this range and a median grant of $295,000, so a request in that range is realistic; the largest grant, around $10,500,000, went to ArtsFund, an organisation it funds every year and which regrants to other organisations, making this an outlier rather than a typical award.
  • Around 79% of its grant dollars went to organisations it had also funded in earlier filings, so repeat partners take the larger share of its giving and new applicants may find it competitive to break in.
  • How to apply varies by programme; for its Accelerating Natural Solutions in the United States programme, the process runs in two stages, a letter of interest reviewed on a rolling basis followed, for those selected, by a full proposal, and that programme will not fund activities that attempt to influence legislation or the outcome of any election.
  • Funding decisions are made case by case against programme priorities, so tailoring an approach to the specific theme and programme is likely to matter more than a generic pitch.
