Confirmed positions include Alector, PMV Pharmaceuticals, and RAPT Therapeutics. It also maintains exposure to early-stage biotechnology and robotics companies such as Codagenix and GrayMatter Robotics. Geographic reach centers on the United States with additional international grant activity. The organization employs 529 people. It operates the Flatiron Institute for computational science and leases expansion space at 162 Fifth Avenue. A $100 million pledge supports the New York Climate Exchange on Governors Island. In 2023 the foundation committed $500 million to Stony Brook University.
