CompStak addresses a critical challenge in commercial real estate: the scarcity and opacity of reliable transaction data. By crowdsourcing lease and sale comparables (comps) from industry professionals and applying a rigorous verification process, CompStak provides granular, analyst-reviewed data that is often difficult to obtain through traditional channels.
The platform offers detailed data on lease terms (e.g., starting rent, free rent, tenant improvements), sale transactions (e.g., sale price, cap rate, NOI), loan details (e.g., lender, loan amount, maturity), and property characteristics (e.g., building class, year built, parking ratio). This breadth of data enables CRE professionals to perform accurate asset valuations, market research, underwriting, and due diligence.
CompStak’s crowdsourcing model incentivizes data sharing by granting free access to contributors via CompStak Exchange, fostering a collaborative ecosystem that benefits the broader CRE community. Its premium offerings, such as CompStak One, provide deeper analytics and comprehensive datasets for institutional users.
The integration of AI tools, including CompScout for data queries and Rent Predictor for pricing optimization, further enhances the platform’s value by enabling users to extract actionable insights efficiently.
Founded in 2012 by Michael Mandel and Vadim Belobrovka, CompStak has grown from a startup into a recognized leader in commercial real estate data. The company remains privately held and independent, with a workforce exceeding 100 employees distributed across major U.S. cities and an international office in Belgrade, Serbia.
CompStak’s mission centers on increasing transparency and efficiency in the CRE industry by democratizing access to high-quality transaction data. This mission has earned the company recognition for workplace culture, including five consecutive years on Crain’s Best Places to Work list.
In the competitive CRE data market, CompStak distinguishes itself through its crowdsourced data model, which contrasts with traditional providers that rely heavily on proprietary data collection or public records. This approach allows CompStak to maintain a large, frequently updated dataset with granular details that are often unavailable elsewhere.
CompStak provides nationwide coverage across more than 105 U.S. markets, encompassing a wide range of commercial property types including office, industrial, retail, and multifamily assets. The platform’s data categories include:
CompStak’s data is primarily crowdsourced from CRE professionals who contribute lease and sale comps in exchange for access to the platform’s data. This model encourages timely and accurate data submission. To maintain quality, CompStak applies a rigorous verification process involving analyst review and cross-referencing with public records and other data sources.
Despite these measures, some users report that data accuracy is estimated at around 90-95%, reflecting the inherent challenges of crowdsourced data completeness and correctness.
