CompStak
Commercial real estate data, straight from the source
CompStak is a crowdsourced commercial real estate data platform that addresses the lack of transparent, verified transaction data in the CRE industry. It enables professionals to contribute lease, sale, loan, and property data from deals they have worked on, and in return gain access to comparable data contributed by thousands of other professionals across 105 markets. This model solves the problem of relying on limited personal networks or outdated internal databases for underwriting, valuation, and market analysis.
The platform offers several products and capabilities. The Exchange platform allows users to contribute and access comps. CompStak One Connect is a tier that includes Agent Connect, an MCP server that integrates verified comps into AI tools like Claude, ChatGPT, and Copilot, as well as a Rent Predictor feature. Deal Radar is available in beta. Data can be accessed through the platform, APIs, and data delivery integrations. The platform covers major asset types including office, industrial, retail, and multifamily.
CompStak is designed for a wide range of CRE professionals, including brokers, appraisers, asset managers, lenders, owner-operators, private equity firms, and government agencies. The platform is available on a subscription basis to qualified lenders, landlords, and investors. The pages do not specify a free plan, trial, or seat-based versus usage-based pricing.
