Lease guarantee platform connecting renters and property managers

Financial Services Portland, OR 51–200 employees Founded 2019 Privately Held

OneApp operates a lease-guarantee product designed to reduce approval friction between renters and property managers. The tech stack is dominated by property-management platforms (Yardi, Entrata, RealPage, AppFolio) paired with a modern backend (Node.js, React, TypeScript, Java/Spring), indicating OneApp sits in the integration layer between legacy PM software and new tenant-facing applications. Active pain points around platform adoption, integration scaling, and legacy Java modernization suggest the company is managing both rapid growth in partner onboarding and technical debt from earlier architecture choices.
