Arcus Foundation

Jon Stryker established the Arcus Foundation in 2000. The foundation functions as a private grantmaking institution with an explicit dual mandate covering LGBTQ social justice and great ape conservation. The foundation allocates capital through grants rather than traditional fund commitments. Confirmed positions include a 23.79 percent allocation to private equity and a long equity stake in Stryker Corp. It also maintains direct ownership of mixed-use properties such as 134 Spring Street and 150 Wooster Street in New York as well as residential projects in Brooklyn and the Hudson Valley. Geographic reach covers the United States and international conservation sites including Fort Pierce, Florida. The foundation employs Cambridge Associates as investment advisor. It lists no additional offices beyond the New York headquarters. A dated operational event from the record shows participation as panelist at the IUCN World Conservation Congress in 2025. The foundation maintains a 100 percent owned operating company, Arcus Development, that executes real estate acquisitions separately from grant decisions. This separation creates a distinct governance line between philanthropic distributions and asset management.
