The Sontag Foundation
At a glance
Key takeaways
- The Sontag Foundation is dedicated to advancing brain cancer research, so it is a strong fit only for organisations and investigators working in this field, including therapeutics, diagnostics, medical devices and other technologies; its geographic focus is the United States and Canada.
- Around eight in ten of its grants to organisations fall between $10,000 and $250,000, with a median grant of about $115,000, so a request in that range is realistic, though it has also made a single $3,000,000 grant to an organisation that regrants to others.
- Named programmes have set amounts: the Distinguished Scientist Award is $750,000, the ASCO Conquer Cancer - Sontag Foundation Young Investigator Award is $50,000, and the AACR-Sontag Foundation Brain Cancer Research Fellowship is $120,000.
- Applications are accepted on a rolling basis, and for the Distinguished Scientist Award this means applying through the online grant portal with recommendation letters and institutional officer approval uploaded by the deadline; this award does not fund projects focused on metastatic brain cancer or clinical trials research.
- The foundation appears quite relationship-led, since 91% of its grant dollars went to organisations it had also funded in the previous two filings, so new applicants should be prepared for a competitive field and may wish to build a connection before applying.

The fund works with both for-profit and non-profit entities, using loans and equity investments to advance its charitable mission and recycle capital.
