718 Interchange
718 Interchange is the workspace where customers access their Seven One Eight Systems products. Search across records, save intelligence, follow activity, and move between Build, Abate, Bids, and Property through one connected account.
Search addresses, properties, companies, contractors, owners, agencies, vendors, filings, and bids.
Move between related properties, companies, filings, permits, violations, transactions, bids, and awards.
Save searches, records, companies, properties, opportunities, and custom lists.
Receive updates when tracked records, properties, companies, projects, or opportunities change.
Connected intelligence
Public information is spread across separate agencies, databases, and formats. 718 Interchange organizes those records and reveals how the properties, companies, and filings behind them connect.
Understand the companies, properties, and relationships around any single record.
Spot new activity, filings, and solicitations before they become obvious.
Replace hours of manual record-pulling with organized histories and rankings.
Built for the people who build New York
Each team searches the same record and takes something different from it — a lead, a bidder’s history, a compliance trail, a portfolio.
Find work earlier and qualify who you build with
Example
Which owners filed new alteration jobs on your block this quarter, and which general contractors they used last time.
Reach jobs at the moment they mobilize
Example
Which contractors just pulled permits near your yard, and how much work they have filed over the past year.
Know your buildings and your contractors
Example
Whether a bidder on your project has open violations, and what else they have built for owners like you.
The full abatement record in one place
Example
Which buildings filed for abatement this month, and which air-monitoring firms those contractors normally work with.
Diligence with a documented trail
Example
Who filed what and when on a building, and which entity actually held title on the date in question.
Read the market from the paper trail
Example
Which owners are assembling parcels in a submarket, and which of their sites already have filings in motion.

The parent company
We are a Brooklyn data company. We build and operate 718 Interchange, and we run the collection, structuring, and entity resolution behind it ourselves, which is why a contractor, an owner, or a parcel resolves to the same record in each product.
Public records are collected, structured, matched, and refreshed on an ongoing basis so users can work from organized and current information.
Seats, teams, saved lists, alerts, exports, and API access — priced by the products you actually use.
