Use cases
Built for the trades that move first.
Solar / Electrical

Catch the electrification window.

Service upgrades and EV charger installs are the clearest signal a home is solar-ready. Get there before the panel is closed.
Pool

Find permit-filed pool projects in progress.

Every pool permit is a $50-100K homeowner actively spending. They will need decking, landscaping, and electrical. Get there first.
Decking / Outdoor

Ride the spending momentum.

A structural addition or pool permit means a homeowner with budget already committed. Deck, patio, and outdoor living are the natural next spend.
Any trade

New construction, before anyone else.

Net-new homes are blank slates. Every trade gets a shot at a homeowner who has never hired anyone local. First contact wins.
