# Doorstep

> Doorstep (doorstep.ai) is an indoor precision-tracking platform for last-mile delivery. Its patent-pending Dropoff SDK runs on a delivery driver's smartphone and uses sensor fusion to detect delivery events indoors — parking, building entrance, floor, and the final doorstep — even in GPS-degraded environments. Doorstep raised an $8M seed round led by Canaan Partners (September 2025) and is live across most U.S. states.

Doorstep is a client-side mobile SDK, not a public REST API. Integration is a four-touchpoint lifecycle: set the API key (a JWT), request permissions, start delivery tracking, mark the drop-off, and stop tracking. The SDK ships for React Native, Flutter, Capacitor, native iOS, and native Android.
