CompStak is a commercial real estate (CRE) data platform, founded in 2012, that crowdsources and verifies lease comps, sale comps, loan data, and property data from a network of tens of thousands of brokers and appraisers across US markets. Its products include CompStak One (an all-in-one CRE data platform), CompStak Exchange, CompStak AI, and a contact-sales Data API offering Market Insights, Property Insights, Space Insights, and Property Standardization.
