# Key concepts

> The core building blocks of Metal, explained in plain language.

A quick, non-technical tour of the ideas you'll see throughout Metal.

## Companies, deals, and people

* A **company** is an organization you track — a target, investor, advisor, or service provider.
* A **deal** is an opportunity, linked to a target company, that moves through your pipeline.
* A **person** is a contact or executive, often linked to a company.

## Files

Upload documents — CIMs, financials, memos — to companies and deals. Metal processes them so their contents turn up when you search. See [Files & documents](/help/documents).

## Lists

**Lists** are grids that group companies, deals, people, or documents so you can work with them together — including AI-enriched and computed columns. See [Working with lists](/help/lists).

## Enrichment and scoring

**Enrichment** fills in details about companies and people automatically. **Scoring** evaluates deals and companies against your firm's frameworks. See [Enrichment](/help/enrichment).

## Workflows

**Workflows** automate multi-step research and produce work product. Each execution is a **run**. See [Using workflows](/help/workflows).
