About Compstak
CompStak is the leading crowdsourced commercial real estate lease comp and sales comp data platform. Its 35,000+ member network of CRE appraisers, brokers, and researchers contribute authenticated lease and sale transaction data covering all US markets. Unlike CoStar which employs researchers, CompStak leverages a unique exchange model where members contribute comps to access the database. This produces highly detailed, granular deal-level data including effective rent, TI, free rent, and lease terms that are difficult to find elsewhere. CompStak serves institutional investors, lenders, appraisers, and brokers.
