# Stewart Butterfield (@stewart-butterfield)

Stewart Butterfield is listed in the registry as a founder; this profile reconstructs that identity through person-specific institutional and bibliographic records tied to company-building record. Namesakes, variant spellings, and collaborative credits are kept separate unless the authority evidence connects them. A filing search result, including a Form D notice, does not by itself establish that the named person is a founder or investor; that status requires separate person-specific evidence.
