Smart Apartment Operations at Scale
Manage thousands of units across cities from a single dashboard. Zero key handovers, zero on-site visits, full operational visibility.
Solution Overview
One Platform. Every Unit. Every City.
When a new tenant signs in your booking app, a unique time-limited passcode is generated automatically — no on-site staff, no physical key.

Pain Points & Approach
Multi-Property Management Is Broken
Every key handover, every late-night lockout, every empty unit eating utility bills — these are pure margin loss.
Physical Key Chaos
Lost keys, duplicate keys, manual handovers — a single missing key can cost $200+ to rekey a unit.
Empty Unit Energy Drain
HVAC and water heaters often run between tenancies — unmonitored vacant units burn 30% of yearly utilities.
Distributed Properties
Managing units in different cities and timezones means constant on-site trips and zero real-time visibility.
Reactive Maintenance
Tenants only report issues after damage occurs — leading to expensive emergency repairs and bad reviews.
Typical Workflow
From dynamic passcodes to AI-driven energy optimization for vacant units — all on a single cloud dashboard.

Key Functions
Built for Distributed Portfolios
Run hundreds of properties with the staffing of a small team.
Multi-Property Dashboard
Manage thousands of units across cities from one cloud — group by building, owner, or region.
Dynamic Remote Passcodes
Time-limited, one-time, or recurring PIN codes for tenants, cleaners, and agents — generated remotely without Wi-Fi at the door.
Zero Key Handover
Mobile keys + dynamic PINs eliminate physical key exchanges entirely — onboard a tenant in 60 seconds.
Vacant Unit Energy Saving
AI detects vacant units and automatically dials back HVAC, lighting, and water heating — instant utility savings.
Real-time Alerts
Door pry, low battery, water leak, smoke — escalation routed to the right manager in real time.

Project Snapshot
850-Unit Co-living Operator
Tokyo + Osaka
Case Study
Background
A growing co-living brand operated 850 units across two cities with a 6-person property team — onboarding was the bottleneck.
Challenge
Manual key handovers, frequent lockouts, and vacant-unit utility bills consumed nearly 15% of monthly revenue.
Solution
Replaced legacy locks with our smart locks + multi-property cloud + AI vacancy detection. Rolled out in 4 months.
