Key takeaways

  • If your work is MAPK8IP3 research or the search for treatments for ultra-rare central nervous system diseases, the foundation's focus fits closely, since it funds academic researchers at universities and is receptive to novel ideas with disease-modifying potential.
  • Its stated geographic focus is around the world.
  • Its typical grants fall between $2,500 and $270,000, with about 8 in 10 of its 73 grants in that band, but the median grant was $25,000 and half its grants were $25,000 or less, so a request near that figure sits at the centre of its giving; its largest grant was $6,000,000.
  • In the filing, 88% of grant dollars to organisations went to organisations it had also funded before, so a first approach should make a clear case for fit rather than expect a quick reply.
  • It does not issue requests for research proposals, so send an unsolicited idea, and keep the budget free of overhead or indirect costs, which it does not fund.

Overview

The Wolverine Foundation is a US private foundation based in Greenwich, CT.

What they fund

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

Priority Areas

The Wolverine Foundation funds and works with academic MAPK8IP3 researchers at universities around the world. It supports research to develop effective treatments for MAPK8IP3-related genetic disorders and potentially other ultra-rare central nervous system diseases. Its projects investigate disease mechanisms and novel therapeutic approaches, while bringing academic research, drug discovery and clinical development together through scientific collaboration. It makes resources, including models and clinical samples, available to the MAPK8IP3 research community and seeks to bring partners together to address critical scientific issues. It is receptive to novel ideas in biology relevant to MAPK8IP3, particularly therapeutic approaches with disease-modifying potential, and invites possible partnerships with biotech and pharmaceutical companies to develop potential drugs.
