CompStak is a commercial real estate data platform that provides verified lease comps, sale comps, loan data, and property intelligence. Founded in 2012, CompStak crowdsources transaction data from over 40,000 brokers, appraisers, and researchers nationwide, then verifies it through a rigorous multi-step process combining AI, machine learning, and expert analyst review.

How does CompStak verify its data?

What markets does CompStak cover?

CompStak provides nationwide coverage across 105 US commercial real estate markets, including all major metro areas. The platform contains data on over 4 million properties and 4 million lease and sale transactions across office, retail, industrial, and multifamily asset types.
