No more routine
Every one of these becomes a ticket, gets solved and stays on record. One platform to run the whole building.
One platform built for how a property manager (Hausverwaltung) actually runs a building in Austria.
One platform, three layers
Operations
CRM and apps for residents and technicians. Requests become tickets, notices arrive with read receipts.
Building
Intercoms, access control, cameras, meters, EV chargers and building systems. The hardware layer most platforms leave out.
Intelligence
AI answers calls, files tickets and writes reports. Nothing happens without your approval.
Built for the people who run buildings
Platform
Your command center for requests, resident communication, meter readings and analytics.
Resident App
Notices, requests, meter readings and votes right in the resident app.
Technician App
Today’s jobs, routes, photos and checklists, right in the field.
AI Tools
A concierge that answers calls and reports that write themselves.
Meter readings
Owners submit their own meter readings in the app, within the reading period — no slip of paper in the mailbox.
Also equipping buildings with smart systems
Access control, video intercoms and remote meter reading for new and existing buildings.

Everything a building needs
Modules connect to the same platform and the same resident app. Start with requests and notices, add the rest when you need it.
Booking
Residents book the gym, sauna or meeting room and pay in the app.
Digital passes
Guest and courier passes, doors open from the phone.
Meter telemetry
Readings arrive automatically, nobody knocks on doors.
Digital intercom
Intercom calls go straight to the resident’s phone.
EV charging
Stations on the map, sessions booked and paid in the app.
Building management
Ventilation, heating, power and lifts under remote control.
AI Reports
Upload raw files, get a clean report. Excel, accounting systems, even WhatsApp exports.
Video surveillance
Live cameras, archives and plate recognition at the gate.
Developer showcase
Sell your next building to people who already live in one of yours.
Marketplace
Paid services from the management company and its partners.
Open API
Connect your billing, ERP, chatbots or devices.
Works with what you already use
Through an open API you connect Unitify to banks, accounting systems, building technology and chatbots.
Your accounting stays
Invoicing (Vorschreibung, the monthly charge notice), Hausgeld (owners' advance contribution) and the annual statement keep running in your management software. Unitify is the layer for owners on top: notices with read receipts, requests with status, meter readings and votes.
- Owners submit their own meter readings in the app, within the reading period.
- Requests become tickets with a status — the owner sees where things stand until it is closed.
- Notices reach owners by app, email and building website, with read receipts.
Meet your 24/7 dispatcher
AI Concierge answers every call and chat, creates tickets and keeps residents posted. A human approves every decision.
- Resident: Hello! I just noticed there’s no hot water in my apartment. Could you look into what’s going on?
- AI Concierge: Hi there! Thanks for letting us know. We’ll send a technician to take a look within the next hour. Could you confirm someone will be home?
- Resident: The technician, Thomas, just left — everything works.
- AI Concierge: Glad to hear it! I’ve marked the request as resolved. From your first message to the fix: 52 minutes.

Questions Austrian property managers (Hausverwaltungen) ask
What is a Bauwerksbuch (building logbook)?
An ongoing electronic record of a building’s structural condition and maintenance history, required under Vienna building law so the city and the owners have a current picture of the building’s state rather than reconstructing it from paper files when something needs checking.
Is a virtual owners’ assembly (Eigentümerversammlung) permitted?
Under the WEG 2002 (Austria's condominium act), an Eigentümergemeinschaft (owners' community) can pass resolutions in writing (Umlaufbeschluss) without a physical assembly if the required majority agrees in that form; whether a fully virtual assembly format is available follows the community’s own rules and the appointed manager’s (Verwalter) process, not a single blanket provision comparable to Germany’s 2024 virtual-assembly rule.
Which buildings are subject to the Bauwerksbuch requirement?
New buildings, additions and conversions within Vienna, before the completion notice is filed, under Section 128a(2) Bauordnung für Wien. Existing buildings fall under the duty in Section 128a(3), with staggered deadlines. The law exempts Kleingartenhäuser, Kleingartenwohnhäuser and buildings with a built-up area of 50 square meters or less. It is a Vienna city rule, not automatically applicable in other Austrian states.
By when must a Bauwerksbuch be created for older buildings in Vienna?
Buildings from before 1 January 1919 by 31 December 2027, and buildings from 1 January 1919 to 1 January 1945 by 31 December 2030, registered electronically in the city’s Bauwerksbuch database.
What is an Eigentümergemeinschaft (owners' community) under the WEG 2002?
The community formed automatically among the owners of a building once more than one unit exists, which decides on shared matters and appoints a Hausverwaltung (property manager) to run day to day operations on its behalf.
Can you connect the intercom or access hardware we already have?
Usually yes. If the panel, controller, camera or meter exposes an integration interface (an API, SIP, ONVIF or a Modbus or M-Bus gateway), we connect it to the resident app under the project. Barriers with plate recognition, lift access and in-apartment smart home are handled the same way, as project work. Hardware with no interface cannot be connected, and we check the exact model before you commit.
