# Bridge-specific columns

> The structured, standardized columns available for each Bridge type — what they contain and how to use them as enrichment inputs.

**Bridge-specific columns** let you enrich a Bridge's underlying object with standardized data. You can add more than one at a time, and each appears in its own column. These columns are useful as inputs into AI Analysis and Personalized Outbound Email columns.

<Note>
  Buyer and Contact Bridges aren't anchored on a signal, so their structured columns are **buyer attributes** and **contact fields**, rather than signal attributes. Those two sections are flagged below.
</Note>

To add any of these, open your Bridge, click **"Add encihment"**, and choose the bridge-specific column(s) you want.

## Contracts & POs Bridge columns

Anchored on purchase orders and contracts (Starbridge spend data sourced from FOIA records and web enrichment). These columns surface key details such as contract values, expiration dates, renewal windows, and incumbent vendors, helping you identify competitive replacement opportunities before they go to bid.

## Meetings & Plans Bridge columns

Built around board meetings, meeting minutes, agendas, and strategic plans. These columns surface key details from each document.

<Tip>
  **Relevant Snippets column** identifies the most important quotes from a meeting based on your search criteria and buyer context. Click any snippet—from your Bridge, Feed, or email digest—to jump to the exact place where it was mentioned, making it easy to verify context and prepare for outreach.

## Buyers Bridge columns

<Info>
  **Entity Bridge.** A Buyer Bridge is anchored on a list of accounts, not a signal, so its structured columns are **buyer attributes** (buyer type, location, size, enrollment, budget, and more), collected and kept current by Starbridge. See [All Starbridge Data](/data/buyer-attributes) for the full attribute reference.
</Info>

## Contacts Bridge

<Info>
  **Entity Bridge.** A Contacts Bridge is anchored on people, not a signal, so its structured columns are **contact fields** (name, title, email, activity status, and related details) rather than signal attributes. See [Enriching Contacts: Contact Bridges](/builders/contacts-bridge) for how contacts are sourced and verified.
