About Us

Any analysis is only as good as the data on which it's based.

Real estate market data is startlingly opaque. Information about most individual transactions is publicly available in city documents, but is generally difficult or time-consuming to identify and interpret. The online sites provide incomplete, contradictory, or irrelevant data. Square footage is often treated like a state secret. Other websites withhold relevant deal data so that users need to contact brokers. We saw a need for accurate, detailed data from a neutral party with no stake in the transaction.

We thought this would be easy. But even data as basic as commute times, and neighborhood boundaries turned out to be contentious. As we addressed these, we realized that numbers alone could not tell the whole story. So, we created beach neighborhoods in New York City? Or that so many neighborhoods were affected by airport noise?

Our vision was to allow users to make more informed decisions. Users should be able to see historic districts within neighborhoods, as well as flood zones or properties which might be too close to highways or elevated trains.

There are three key questions in New York City real estate: where are the pockets of overlooked value? What hot neighborhoods may already have the upside priced in? And which inexpensive neighborhoods may not be bargains? Our goal is to provide the data that helps answer these questions.
