Geospatial ‘Visits’ or point of interest | US only

Our proprietary machine-learning model merges raw GPS signal with precise polygon places to understand which pseudonymous device visited which POI at which time.

**Reliable Results**: The result is reliable, accurate, device-level visits, refreshed, and delivered daily. In other words, “X pseudonymous device id visited Y Starbucks at Z date and time.

**Data Made Easy**: We do the heavy pre-processing so you don’t have to. We cleanse the raw GPS data and use our proprietary machine-learning model to cluster the GPS observations into predicted visits. Then, we match these clusters with high-quality POI polygons.

**Device Coverage**: Visits features coverage of ~6% of the USA population, or approximately 15M pseudonymous devices visiting 4M places each day.
