Pushpin applies deep learning to aerial imagery to achieve automatic parcel change detection and impervious surface extraction. Pushpin provides next-generation property change detection leveraging a patent-pending, semi-automated workflow that consistently achieves human-level accuracy or better. Pushpin flags changed parcels, indicates one or more change type, and divides parcels into geographic sectors. Pushpin delivers all of this at 70% lower cost than the competition. Pushpin also supports impervious surface extraction. For this, Pushpin leverages a patent-pending, semi-automated workflow that enables municipalities to rapidly catalog impervious surfaces for commercial and residential properties. Pushpin enables assessors to quickly and accurately calculate surface water management fees and storm water utility fees thereby increasing tax revenue. Pushpin's founder and president is Randy Milbert. Randy is an MIT graduate who previously served as founder and president at Primordial, which developed off-road route planning software for the military. In 2013, Randy sold Primordial to Polaris Industries (NYSE:PII).
