CompStak

What CompStak does

CompStak is a New York-based commercial real estate transaction data company founded in 2012 by Michael Mandel and Vadim Belobrovka. It operates a crowdsourced data platform in which more than 40,000 brokers and appraisers contribute lease, sale, and loan comps that are reviewed by CompStak's internal analyst team and normalized through a proprietary CRE ontology for entity resolution. The platform covers 105 US markets and contains more than 4 million comps, supporting enterprise use cases in underwriting, valuation, asset management, and portfolio reporting.

The company's product portfolio spans CompStak Exchange (the data-contribution network), CompStak One (the unified subscription platform aggregating lease, sale, loan, and property data plus analytics and the new Portfolios module), CompStak AI (an AI overlay with CompScout natural-language search, Rent Predictor, and AI Market Summary), a public API with MCP workflow integrations, CompStak Prospect (B2B lead generation), and a recently launched Strategic Advisory consulting practice. Data products are delivered via annual enterprise subscriptions with quote-based pricing, alongside professional-services revenue from Strategic Advisory.

CompStak's go-to-market is enterprise sales-led, targeting institutional investors, REITs, lenders, brokers, appraisers, and corporate occupiers; named customers include MetLife, PIMCO, CPP Investments, Wells Fargo, Mitsui Fudosan, BGO, Tishman Speyer, and GFP. The company has raised over $80 million in venture funding across multiple rounds (seed through a $50 million Series C led by Morgan Stanley Expansion Capital in November 2021) and maintains its headquarters at 675 Avenue of the Americas in New York City.

Emerging players

• Crexi: CRE marketplace and data platform with listing, comp, and market intelligence tools for brokers and investors. Comparable to CompStak's exchange-plus-data offering but with stronger emphasis on transaction listings.
• HouseCanary: Real estate analytics platform providing valuation, market data, and AI-driven insights for residential and commercial properties. Overlaps with CompStak's predictive analytics capabilities, particularly the Rent Predictor product positioning.

Broad incumbents

• CoStar Group: The dominant CRE data and analytics incumbent, offering LoopNet, Apartments.com, and CoStar Suite across commercial and residential real estate. CompStak competes head-on in lease/sale comps but CoStar operates at vastly greater scale and breadth.
• Yardi: Comprehensive CRE and multifamily software platform with a growing analytics and data layer (Yardi Market Analytics). A broader incumbent offering competing CRE intelligence tools alongside its core property management suite.
• RealPage: Provider of property management, data analytics, and CRE intelligence software used by landlords and lenders. Overlaps with CompStak in CRE transaction and market data, and is also a historical investor in CompStak, making it a competitor-investor hybrid.

Direct peers

• Reonomy: CRE property intelligence platform now part of Altus Group, providing deep property and ownership data nationwide. Competes with CompStak on CRE property and ownership datasets for institutional investor and broker workflows.
• Cherre: CRE data platform that unifies property, financial, and market data for institutional investors. CompStak and Cherre compete for the same enterprise analytics buyer, with both emphasizing workflow integration and data unification.
• Trepp: CRE debt and CMBS data analytics provider serving lenders and investors. Overlaps with CompStak on loan/CMBS data and is simultaneously a data-share partner and peer competitor in the institutional CRE data category.
• Altus Group: CRE intelligence and analytics platform that acquired Reonomy to expand its data capabilities. Provides property-level data, valuation analytics, and advisory services directly comparable to CompStak's lease/sale/loan dataset.

Others

• Propmodo: CRE-focused media and research outlet that frequently cites and compares CRE data providers including CompStak. Adjacent rather than competitive — a channel partner and ecosystem commentator rather than a data provider.
