What Builtie adds

In Builtie: the decision makers on this project and their verified contacts, the trades already credited on it, the builder's other active permits, and LinkedIn and email outreach that runs while you work.

Other major projects in New York City

All of them: construction projects in New York City by address. All five boroughs are in the feed, which has run since February 27, 2026. New York issues separate permits for each trade, so the firm named on a permit is often the trade contractor, an engineer or an expediter rather than the developer. Builtie groups the permits into projects and resolves the owner and builder separately.
