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.
Hetal Retail
Hetal Retail is a New York-based startup that helps consumer brands see what is actually happening on store shelves. A crowdsourced network of everyday shoppers - called Hetalites - films short videos of store aisles on a mobile app, and Hetal's computer vision and AI turn that footage into planogram-compliance diagnostics, prioritized issue lists with visual proof, and correlations between shelf execution and sales. The pitch: retail-level visibility for a fraction of the cost of traditional manual audits, and a system that helps coordinate the fix rather than just flagging the problem.
