Property data
CompStak
CompStak is a commercial real estate data platform built on crowdsourced transaction data. Brokers, appraisers, and researchers contribute lease and sale comps and get access to the database in return; lenders, landlords, investors, REITs, and advisors buy access by subscription.
Every comp submitted goes through the company's verification process before it enters the data set. The platform brings an asset's lease, sale, loan, and property history together in one place and keeps the transaction-level detail rather than anonymizing and averaging it, which is what appraisers and underwriters need. Data can also be integrated into a subscriber's own systems.
Nationwide coverage is sourced from more than 40,000 brokers, appraisers, and researchers. CompStak One, the paid platform, is available on a subscription basis exclusively to qualified lenders, landlords, and investors. A separate product, CompStak Prospect, repackages the data as a B2B lead-generation tool for insurance, telecom, and other vendors selling into commercial real estate.
Launched in 2012, CompStak is independent and privately held, with over 100 team members and offices in New York, Los Angeles, Chicago, Atlanta, and Belgrade, Serbia. Subscription pricing is not published: contributors trade comps for access, and institutional buyers should expect a quote.
