A lead generation engine disguised as a free homeowner tool. Users draw project outlines on satellite imagery and get instant cost estimates — no signup required. That zero-friction experience builds a high-intent audience that converts into qualified leads for local service providers.
Covers fencing and driveways across 980+ cities in all 50 states, with roofing next. Every estimate is a homeowner who's actively pricing a project — and ready to hire.
Deeper case study coming soon.
