About
MagicDoor is the first AI-native property management platform, built from the ground up to automate the operational workflows that consume property managers' time and budget. Founded to rethink property management software for an AI-first era — rather than bolting AI onto legacy tools — MagicDoor's architecture treats automation as the default, with human intervention as the exception. The platform was designed to serve independent landlords and small-to-mid-size property management companies managing residential portfolios.\n\nMagicDoor's platform handles tenant screening, lease generation, maintenance request routing, rent collection, accounting, and owner reporting through a unified AI workflow layer. Customers report 5x productivity gains and 60% cost reductions compared to legacy property management software and manual processes. The AI handles communications, document generation, and task routing autonomously, allowing property managers to scale their portfolios without linear headcount growth. The product targets the fragmented small-to-mid market that legacy players like AppFolio and Yardi have traditionally underserved on price and automation depth.\n\nMagicDoor raised a $4.5 million seed round in September 2025 and has demonstrated triple-digit monthly growth since launch. The company operates in the $20 billion US property management software market, where AI-native competitors are beginning to displace incumbents by offering dramatically better automation at lower cost. MagicDoor's seed-stage traction and growth velocity signal strong product-market fit ahead of its next funding stage.

About
CoStar Group is the leading provider of commercial real estate data, analytics, and marketplace platforms, founded in 1987 in Washington, D.C. by Andrew Florance.
