Rentsync Tech Stack

Rental marketplace and leasing platform for Canadian housing operators

Software Development Toronto, Ontario 51–200 employees Founded 2010 Privately Held

Rentsync operates a dual-product ecosystem (Rentals.ca marketplace + Building Stack leasing software) serving Canadian rental housing operators. The tech stack is heavily .NET-based (Core, C#, Entity Framework) with React/TypeScript on the frontend, running on Azure DevOps — a mature, enterprise-grade foundation. Current engineering work centers on legacy system refactoring (.NET 4.8) and billing system overhaul, suggesting an inward turn toward operational stability and financial systems modernization rather than feature expansion.
