Fund Letters

Get a fund-letter investor

Returns an investment firm's full fund-letters profile: identity and principals, the strategy/style/focus profile evidenced across its letters, coverage stats, every fund with published letters, and the complete letter feed (newest first).

Investor identifiers are permanent. When two investor records are ever discovered to be the same firm they are merged rather than deleted, so a previously returned investorId keeps resolving.

Free-trial keys can read the investors listed by /v1/fund-letters/investors; other investors return 403.
