CompStak is a commercial real estate data company that collects lease comparables, sale comparables, loan data, and property information through a crowd-sourcing exchange of brokers, appraisers, and researchers.[1] Launched in 2012 and headquartered in New York City, it positions its transaction-level detail as an alternative to anonymized or averaged CRE data.[1]
Its platform covers the United States with figures cited by the company of roughly 4 million comps received, 4 million properties, and 105 markets, sourced from a contributor base the company numbers at more than 40,000 CRE professionals.[1]
What It Does
CompStak operates a two-sided exchange: commercial real estate professionals contribute deal-level information, which the company verifies and resells through subscription platforms.[1] Lease comps capture terms such as starting rent, free rent, tenant improvements, escalations, square footage, tenant industry, and expiration dates; sale comps record price, cap rate, net operating income, buyer, and seller; loan data covers lenders, amounts, maturities, and loan-to-value ratios.[1]
The company states every comp undergoes an extensive verification process combining crowd-sourcing with proprietary data-quality methodology.[1]
Products
Flagship products include CompStak Exchange, aimed at CRE professionals at brokerages and appraisal firms who trade data contributions for access, and CompStak One, an all-in-one analytics platform unifying lease, sale, loan, and property history.[1] The portfolio extends to CompStak AI, a data API for integrations, strategic advisory services, and Prospect, a data-driven business development tool.[1]
Coverage spans office, retail, industrial, and multifamily asset types.[1]
Buyers and Use Cases
Customers include institutional investors and operators; the company displays logos including MetLife, PIMCO, BGO, Columbia, and Mitsui Fudosan as users of its platform.[1] Journalists at outlets including The Real Deal, Bisnow, Commercial Observer, and GlobeSt. regularly cite CompStak data in market reporting, and Forbes has described its member base of brokers, appraisers, and investors delivering authenticated U.S.-wide data.[1]
Published analyses using CompStak data have examined topics such as office leasing by artificial intelligence companies in San Francisco and post-pandemic flight to quality across major U.S. office markets.[1]
