    • The name "get_investor" says "get": a word for reading.
    Description, as the server wrote it
    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.

    Why it is in this group

    • The name "list_investors" says "list": a word for reading.
    Description, as the server wrote it
    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.

    Why it is in this group

    Description, as the server wrote it

    Why it is in this group

    • The name "search_investors" says "search": a word for reading.
    Description, as the server wrote it
    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.
