Toronto’s rental market is no stranger to inefficiencies, but one local founder is leveraging AI to fix the broken leasing experience for both landlords and tenants. CasaYa, founded by entrepreneur Andres Parra Arze, is building what it calls an “end-to-end leasing platform” to cut vacancy times, reduce fraud, and make renting more transparent.
“I ran into paper-heavy, outdated processes, lost leads, and slow decisions,” Parra Arze told The Founders Press. “Friends had the same experience—one even ended up without housing after a failed application and delays. I mapped the full leasing journey and saw the legacy stack hurts everyone.”
That pain, he says, is what led to CasaYa’s creation. “CasaYa was built to fix that end-to-end—cutting costs and time, reducing risk, and matching the right resident to a homeowner’s most important asset.”
CasaYa is already live with early adopters in Canada and is piloting in California. “Interest from independent landlords is strong, especially where vacancies and fraud screening are pain points,” Parra Arze noted. The startup is onboarding a limited cohort this quarter while expanding integrations with listing platforms and payment systems.
The platform serves both sides of the rental equation. For landlords, CasaYa handles listing syndication, lead capture, tenant pre-qualification, fraud and income checks, showing coordination, e-leases, and audit trails. The result, according to the company, is fewer vacancies, less manual work, and reduced risk.
For renters, CasaYa promises transparency and speed. “Renters get instant answers, guided document upload, self-serve tour scheduling, and rapid pre-qualification,” Parra Arze explained. “The path from inquiry to keys is faster and fairer.”
At the heart of CasaYa’s platform is artificial intelligence. AI agents manage 24/7 applicant conversations and workflow orchestration, while machine learning models scan for fraud, identity anomalies, and document tampering. “Everything is human-in-the-loop with full logs,” Parra Arze emphasized, adding that policy-aware prompts are designed to stay aligned with fair-housing guidelines.
The rental industry, Parra Arze believes, is on the verge of consolidation.
“Leasing ops are consolidating into AI-native platforms. Verification and fraud prevention are becoming table stakes. Renters expect consumer-grade speed and transparency. The winners will be autonomous, compliant, and interoperable.”
CasaYa is preparing to launch pilots in Santa Monica and San Francisco, while also deepening integrations with payments and listing platforms. The startup is also inviting landlord associations and property managers into what it calls a “limited seat program” to test AI-powered leasing tools this quarter.
