CompStak uses a crowd-sourced model to gather real estate information that is hard to come by, difficult to compile, or otherwise unavailable. CompStak's wedge into the market is a platform for the exchange of commercial lease comps. Brokers, landlords, appraisers and researchers use their site, and submit comps on completed commercial lease transactions. Users receive points for submitting comps, and may use those points to buy other comps. As a result, CompStak builds a comprehensive database of all of the commercial lease deals completed in a given market, and they sell this data to real estate private equity funds, asset managers, banks, REITs, hedge funds, etc.
