# Facts (/docs/core-concepts/facts)



**Facts** are canonical knowledge-graph entities: an organization, an investment round, or an acquisition. They have stable IDs, dates, amounts, and parties — not document text.

Use facts when you need **deal or company structure** (who invested, how much, when a company was founded). Use [proof points](/docs/core-concepts/proof-points) when you need the articles or filings that mention those entities.

Connect exposes `POST /facts/{organizations|investments|acquisitions}/search` and `/time-series`. See the [Facts](/docs/facts) guides.

How organizations are resolved into the graph is covered in [Organizations](/docs/core-concepts/organizations).
