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.
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.
To add any of these, open your Bridge, click “Add enrichment”, 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.

Sample columns available for this Bridge type.

​
RFPs Bridge columns

Built around active bids and procurement postings. These columns surface key details such as due dates, budgets, procurement contacts, and submission requirements.

​
Buyers Bridge columns

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 for the full attribute reference.

​
Custom Web Signals Bridge columns

Built around custom topics, events, or buying signals you want to monitor across the web—such as grants, funding announcements, construction projects, leadership initiatives, or news mentions.

Sample columns available for this Bridge type.

​
Contacts Bridge

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 for how contacts are sourced and verified.
