Fundable / Discover investor firms by their attributes and investments

Use this endpoint when the requested result is a list of investor firms. Filters under company_investments identify qualifying portfolio companies and deals, then return the firms that participated in those deals. For example, use this route to find San Francisco-based investors that participated in a Seed round during the last year. Use POST /people with investor filters instead when the desired result is an individual angel investor or lead partner attached to a firm. Use POST /deals when the desired result is the matching funding rounds themselves. ## Request Body Structure Send a JSON body with up to 3 filter sections plus pagination/sort at the top level: - identifiers - Look up specific investors by UUID, domain, LinkedIn, or Crunchbase - investor - Filter by investor entity attributes (location, employee count) - company_investments - Filter by portfolio (industries, deal characteristics, etc.). Supports semantic search via search_query + min_relevance. When company_investments filters are active, filtered_deal_count is the number of deals that matched those filters and filtered_lead_count is the number of those matched deals the investor led.
