Who is Building Stack?

Headquartered in Montreal, Building Stack was created in 2009 by a team of real estate managers and tech specialists who were searching for a better, more efficient tool to manage their properties and collect rent payments. Frustrated with what the market had to offer, they decided to take matters into their own hands and create a software that truly catered to their specific needs.

That software was perfected over years of tireless work, until it eventually became Building Stack as we know it today, a comprehensive suite of tools for property management, online rent payments, tenant communications, vacancy listing and so much more.

At Building Stack, we know the challenges property managers face every day, and we offer easy, intuitive solutions.
