Key takeaways

  • The foundation's stated focus is the United States, Canada and international, and its themes are mathematical and physical sciences, life sciences, autism research, neuroscience and science outreach, so a request should clearly sit in one of those areas.
  • Its typical grant, where about 8 in 10 grants fall between $8,400 and $275,000, is not a ceiling, since its largest grant was about $26,500,000, and half its grants are $75,000 or less, so a modest request of that order fits well.
  • Most grant dollars go to organisations it has funded before, with 94% of grant dollars going to organisations it had also funded in earlier filings, so a new applicant should expect to compete with established relationships and should make the case for its work carefully.
  • For Targeted Grants in MPS, the foundation accepts rolling letters of intent and favours high-risk theoretical projects of exceptional promise and scientific importance, considered case by case, so approaches there can be made at any time.
  • Application methods otherwise vary by programme, so check the relevant one first, and a new or little-funded organisation is not ruled out by that alone.

Priority Areas

The Simons Foundation makes grants across mathematical and physical sciences, life sciences, autism research, neuroscience, and Science, Society & Culture. Its mission is to advance research in mathematics and the basic sciences, and it describes grant funding, research support and public engagement as parts of its work. In life sciences, it pursues fundamental understanding of life on Earth, with emphases on ecology and evolution, plant biology and microbial systems; it also encourages scientific exchange and supports early-career scientists. Its autism initiative advances basic science on autism and related neurodevelopmental disorders. Through Science, Society & Culture, the foundation supports science outreach for audiences at all stages of development, creating connections between science and culture. It also supports partners and programs that broaden the scientific community and open pathways to science and mathematics careers.
