TopKey is an AI-powered financial operating system purpose-built for professional short-term rental, vacation rental, and long-term rental property managers running 50-5,000+ units. It automates property-level and owner-level expense management, corporate and bring-your-own cards (BYOC), bill pay / AP, banking through partner banks (Thread Bank, Member FDIC), AI-assisted accounting, inventory, invoicing, work-order expense tracking, and revenue reconciliation. TopKey integrates deeply with property management systems (Guesty, Hostaway, OwnerRez, Streamline, Track, Hostfully) and accounting software (QuickBooks Online, Xero, Sage Intacct, Oracle NetSuite). Backed by a16z and Felicis. TopKey consumes partner APIs for its integrations but does not publish a public developer API or OpenAPI at this time; it ships a product help center and a machine-readable llms.txt.
