CompStak
Crowdsourced database of commercial real estate transactions for commercial property
Overview
CompStak is the world's first crowdsourced commercial comparables (comps) database powered by the crowd. The platform collects and verifies data on executed leases and sales, covering 850,000 unique properties across the United States with 75+ data fields per transaction (2.3 million comps in total). It is used by Wells Fargo, Tishman Speyer, AEW, and Moody's.
CompStak offers three products: Exchange (free access for brokers who contribute data), CompStak One (all-in-one subscription including leases, sales, CMBS, and analytics), and Enterprise for institutional clients starting at $1,699/month. A dedicated API allows integration of data into proprietary analytical workflows.
Our verdict
Essential reference for US commercial real estate: if you handle office, retail, or industrial transactions in the USA, CompStak comps are the most reliable on the market. Unnecessary for residential real estate or European markets. The Exchange model (free in exchange for your own data) is an excellent entry point for active brokers.
