Pushpin analyzed changes in 11,637 parcels in Hennepin county, Minnesota. The largest city in Hennepin county is Minneapolis. Pushpin used 1-foot, leaf-off imagery captured in the spring of 2009 and 2015 by Surdex. Pushpin found that 13% of the parcels had changes affecting assessed value. Extrapolating to the county’s 434,208 parcels, this represents a potential annual property tax revenue increase of $28.9M. The following table summarizes the findings.

Chief Technology Officer, Maricopa County Assessor, Arizona
Pushpin is applying to real property assessment the same kind of artificial intelligence algorithms that Google uses in its autonomous cars. Our testbed was a set of four areas of the county, each of which presents a different challenge for change detection via aerial photography. After we examined these small pilot areas with this constantly learning technology, we believe our office has a new opportunity to improve the accuracy, turnaround time, and cost for detecting a variety of changes.
Assessor, Carson City, Nevada
Pushpin delivered high-quality results in days versus months and did so at one-fifth the cost of the competition. Pushpin is applying to property assessment the same kind of artificial intelligence algorithms that Google used to beat world champion Go players. The result is a dramatic improvement in accuracy, turnaround, and cost—and a phenomenal return on investment.
Property Appraiser, Lee County, Florida
We fly new aerial photographs of Lee County every year to help with our parcel inspection and valuation process. Pushpin allows us to leverage that investment by identifying changes in parcels without costly on-site inspections. Having a full accounting of new construction, additions and demolitions is important in developing a fair and equitable tax roll for everyone. Pushpin is a great new tool we plan on utilizing to increase the accuracy of our data collection process.
Assessor, Pope County, Minnesota
Pushpin enabled us to increase property tax equity and revenue by identifying parcels with changes, but no relevant permits. Without Pushpin, it may have been years before we discovered these changes. Pushpin is leveraging machine learning to accelerate a process that historically has been slow and expensive. Their approach provided an excellent return on investment for our office.
Property Appraiser, Hillsborough County, Florida
Pushpin enabled us to analyze our zone 3 properties in a fraction of the time and cost that was previously possible. We performed a careful review of the results and were so pleased that we asked Pushpin to analyze our zone 4 properties in the next fiscal year. We enjoy working with innovative partners like Pushpin that enable us to lower costs and increase efficiency.
