CompStak
CompStak is a New York-based commercial real estate data and analytics company that runs a crowdsourced marketplace where brokers, appraisers and researchers trade verified lease and sale comps for credits. Founded in 2012 by former broker Michael Mandel and engineer Vadim Belobrovka, it turns hard-to-find transaction details - starting rents, net effective rents, cap rates, net operating income - into structured, analyst-reviewed data used by many of the largest CRE investors, lenders and banks in the U.S.
