# investordatabase.org

> A public directory of investors — firms that invest directly in companies (venture capital, private equity, corporate venture, family offices, accelerators, angel networks) and the limited partners that fund them (pension funds, sovereign funds, funds of funds) — with a graph of how they are connected. 21399 investors in 129 countries, as of 2026-11-13. Every record is built only from what the investor publishes on its own website, and every fact carries the page it was read from.

Things to know before using it:
- Coverage is incomplete and uneven by country, and the site says so. Absence from the directory is not evidence that an investor does not exist.
- An investor's "stage" is a range (from–to), not a single value.
- Co-investment links mean two investors list the same company on their own portfolio pages; that is not proof of a shared round.
- Limited-partner links come only from the limited partner's own published fund list.
- People appear only as their firms list them, on the record pages.

## For AI assistants: the MCP server

- [MCP endpoint](https://investordatabase.org/mcp): Model Context Protocol, Streamable HTTP, no key needed, read-only. Tools: `search_investors` (free text plus country / type / stage / sector filters), `get_investor` (one full record with its sources), `get_co_investors`, `get_lp_relationships`, `directory_stats`. Limits: 25 results a call, 200 per query, 60 requests a minute — it is for answering questions, not for copying the directory.
- [How to connect](https://investordatabase.org/ai/): setup for Claude, ChatGPT and other MCP clients, with examples.

## Pages
