VTS is changing the way that commercial real estate (CRE) is done—disrupting a $15 trillion industry by becoming the modern operating system for CRE. We invented the category of leasing and asset management, which allows landlords and brokers to take their entire leasing process online to maximize revenue and performance. Last year, we launched the fastest adopted new product in proptech, VTS Market. Rise Buildings by VTS is leading an entirely new category of software - tenant experience. We also recently launched VTS Data, already getting front-page references in the Wall Street Journal and quoted by Reuters, The Real Deal, Commercial Observer, and many more. Our success shows in our numbers—we hit "Unicorn" status in 2019 and today we have over 12  billion square feet of commercial space managed on VTS on 80,000 buildings in 34 countries, and we’ve expanded to over 400 employees globally. It’s an exciting time to join the VTS team as we continue to grow rapidly and break records.
Our headquarters are in NYC, but we have major hubs in other cities including Chicago, IL, Toronto, CA, and London, UK.
