search_investors | Search 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. params: q*, sector, check_size, page, per_page |
list_investors | Browse 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. params: sector, check_size, page, per_page |
get_investor | 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. params: login* |
list_investor_followers | Public Signed investors who follow the given investor, alphabetically by name. Only public profiles appear on either side, the same as signed.com/@login/followers. params: login*, page, per_page |
list_investor_following | Public Signed investors the given investor follows, alphabetically by name. Only public profiles appear on either side, the same as signed.com/@login/following. params: login*, page, per_page |
list_sectors | The 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. params: none |
list_check_sizes | The 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. params: none |
