BuildZoom connects homeowners and property owners with vetted local general contractors, using data-driven matching across profiles for 4M+ licensed contractors and construction-permit history spanning hundreds of millions of projects. Alongside the contractor marketplace, BuildZoom operates the Building Permit Database (buildzoomdata.com) — a normalized dataset of 350M+ building permits covering 25+ years, 2,400 jurisdictions, and 90% of the US population, plus 6M+ licensed contractors. That data is delivered through bulk data exports (weekly/monthly, full and incremental), a RESTful Data API with batch requests and sub-second latency for property permit history and contractor license/permit lookups, a Data Explorer web app, and a Permit Map. BuildZoom is backed by Andreessen Horowitz (a16z) and Y Combinator.
