One angel investor's public Signed profile by login: bio, investment description, sectors, check size, links, the portfolio companies they've pinned, whether (and where) they take pitches from founders, follower counts, and a few similar investors. Logins come from search_investors or list_investors, or from a signed.com/@login URL. Private profiles are indistinguishable from nonexistent ones.
DiscoveredThe check-size ranges an investor can list on their Signed profile — the valid values for the check_size filter on list_investors and search_investors — smallest to largest, with how many public investors write each.
DiscoveredPublic Signed investors who follow the given investor, alphabetically by name. Only public profiles appear on either side, the same as signed.com/@login/followers.
DiscoveredPublic Signed investors the given investor follows, alphabetically by name. Only public profiles appear on either side, the same as signed.com/@login/following.
DiscoveredBrowse Signed's public angel investor directory: every investor with a public profile, most complete profiles first, optionally narrowed to one sector or one check size. Each result carries the investor's login (for get_investor), what they invest in, the checks they write, their pinned portfolio companies, and whether they take pitches. Use search_investors when you have a name or a keyword.
DiscoveredThe sectors an investor can list on their Signed profile — the valid values for the sector filter on list_investors and search_investors — with how many public investors list each, a one-line description, and example companies. Busiest sectors first.
DiscoveredSearch Signed's public angel investor directory by keyword: a name, a login, or a word from an investor's bio or investment description ("climate", "former founder", "pre-seed"). A query that names a sector also matches investors who list that sector. Only public profiles are searched. Add sector or check_size to narrow the hits; use list_investors to browse a facet without a keyword.
