Key takeaways

  • The foundation's stated remit is San Francisco arts organisations, cancer research and environmental causes, and its filing also shows grants for mental health, education and other purposes, so a well-matched request need not sit within those three themes alone.
  • Contributions are limited to preselected charitable organisations and the foundation does not accept unsolicited requests, so do not send a cold application unless it has invited you.
  • About 8 in 10 of its grants fall between $20,000 and $225,000, and the median grant was $50,000, so a request near that level is typical, although the largest grant was about $1,050,000, so that band is not a ceiling.
  • Most of its grant dollars (85%) went to organisations it had funded in the two earlier filings, so existing relationships carry a lot of weight.
  • The filing gives no deadlines, so there is no timing to plan around.

Overview

The Baker Street Foundation is a US private foundation based in San Francisco, CA.

What they fund

Profile derived from the foundation's IRS Form 990-PF filings (TY2024, TY2023, TY2022) and web pages about the foundation (arionpress.com), with every statement checked against those sources. Sources read on 7 October 2026.

Priority Areas

The foundation’s stated mission is to support San Francisco arts organisations, cancer research and environmental causes. Its recorded grants support a varied range of charitable organisations: their recipients include arts and cultural bodies, universities, health and social-service organisations, and community and environmental organisations. Operating expenses dominate the stated purposes, with other recorded grants supporting endowments, programme evaluation, mental health, immigration defence, technology capacity, education and youth arts. This combines a stated arts, cancer and environmental remit with broad operating and project support, rather than a focus on a single named beneficiary.
