Our Founders

Michael Mandel


A former NYC commercial broker, Michael founded CompStak to fix the inefficiencies of data sharing in the CRE industry. Michael is a regular speaker on the future of commercial real estate, real estate technology, and data transparency. He graduated from Babson College in 2005, where he led the Babson Entrepreneurial Exchange and was a member of the world’s first live-in business incubator, the e-tower.

Vadim Belobrovka


Vadim is Co-Founder and CTO of CompStak. He received his BS in Computer Engineering from Columbia University. His technical interests lie in functional programming and data science. Outside of the demanding world of technology and entrepreneurship, he can be found on the mats – rolling with his fellow Brazilian Jiu-Jitsu practitioners. If you ask him why he is smiling, he will show you a picture of his two little girls.
