Canadian rental marketplace and property management platform
Rentsync operates a two-sided marketplace (Rentals.ca) and leasing software (Building Stack) for Canadian landlords and property managers. The tech stack is .NET/C#–heavy with React/TypeScript on the frontend and HubSpot integration for lead automation, suggesting a mature B2B SaaS product. Active refactoring of legacy .NET 4.8 code and onboarding automation projects indicate the engineering team is modernizing core infrastructure while scaling operational workflows.
