Primer of U.S. activist hedge funds

The high-publicity public investors

Things to note

• This list will be updated when there are notable fund closures or new launches. Updated as of 7/17/2025

• I try my best to only include independent U.S. institutional investment firms, which means excluding:

  • Bank-owned asset management firms, like GS Asset Management (GSAM)

  • Profiles of PMs working at a multi-manager platform (unless they have founded their own firm)

  • U.S. subsidiary of non-American firms (such as Vontebel)

  • Wealth managers, financial advisors, financial planners, etc.

• All firms described are more than $100 million AUM.

• AUM figures are regulatory figures which include leverage if it’s a hedge fund.
