Source List Registry

The catalog of every pre-qualified, marquee, and public list we use to build target universes. These lists shift when we shift verticals. Each list has a source org, URL, pull method, and current status. Pulled lists drill in to the companies.

How this works

Every active vertical pulls from a curated set of these lists. Design Precast uses the Precast / Concrete family. HR.com uses the HR-Tech family. Cross-vertical association lists and public-data triggers apply everywhere. When we add a new vertical (e.g. roofing partner), we activate that vertical's lists and start pulling. When we retire a vertical, we archive without deleting — future re-entry is cheap.
