Building Stack is a property management platform that assists landlords and tenants by automating daily workflows and offering innovative functionalities. The Montreal-based company currently manages 100,000 units across Canada and the United States, with a significant growth rate of 190% in 2019 alone. To enhance its payment experience for tenants, Building Stack switched from its previous provider to Plaid, which now connects to 400% more customer bank accounts. This change has helped prevent over $36,000 in credit card fees and NSF fees every month, totaling $432,000 annually.
