Bring transparency to CRE
Transparency makes the world better. More transparency means everyone wins.
About CompStak
Better, faster deals start with data everyone can trust.
CompStak is the commercial real estate data platform built with the people who make the deals. Brokers, appraisers, and researchers share comps, our analysts verify them, and lenders, landlords, and investors put them to work.

Our mission
We envision a commercial real estate industry in which accurate and transparent data leads to better, faster deals for everyone.
Commercial real estate runs on information, and for too long the best of it lived in inboxes, spreadsheets, and private networks. Two teams could underwrite the same building with very different facts. CompStak exists so the people making decisions are working from the same verified record of what actually happened.
For our members & clients, we will
Create the gold standard in data
Hard-to-find data made accessible. Data quality is king, and it’s our unfair advantage.
Make our clients and members’ lives easier
We care about their needs. We focus on simplicity and making great experiences.
Be friendly
We are accessible, responsive, and we have our members’ and clients’ backs. We care.
Our story
Started by a broker who saw the problem up close.
Michael Mandel was a commercial broker in New York City when he co-founded CompStak with Vadim Belobrovka to fix how inefficiently deal data moved through the industry.
Since launching in 2012, CompStak has been built on a simple premise: submit the comps you have to get the comps you need. Every contribution is verified, so each new comp makes the data better for the next person who relies on it.
Submit the comps you have to get the comps you need.
