About the data
An adviser’s state is where its Form ADV says its main office is. A fund-index firm is placed by the headquarters city the index lists, or by its Form ADV when the city doesn’t tell. Capital sources, LPs, and family offices are placed by the address their own register gives. Angel investors who list themselves are at hottub.vc/investors. Organizations only: no individuals are listed here, and a listing is a public record, not a recommendation. See the methodology.
