The data
infrastructure
for Washington
We compile hard-to-get municipal datasets — permits, zoning, code enforcement, and more — so companies can make smarter decisions about property and place.
Municipal records, structured
for production from day one
We source permits, zoning, code enforcement, and eight more categories directly from local government systems — cleaned, parcel-linked, and delivered via API.
