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 German property manager (Hausverwaltung) runs an owners' association (WEG), day to day.
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.

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, Lukas, 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.

Buildings that run on Unitify
The difference is the routine

Built by a property manager
In 2012 Ilia Sotonin started a residential management company and kept the duty phone under his pillow. The software he built to get some sleep grew into a platform for 10,000 management companies and more than 5 million apartments. Unitify is that platform, rebuilt for the global market.

Questions German property managers (Hausverwaltungen) ask
What is a WEG-Verwaltung (owners' association administration) and what does it actually do?
It is the administration appointed by a Wohnungseigentümergemeinschaft (owners' association, WEG) to run the building day to day: collecting Hausgeld (owners' advance contribution), paying shared bills, keeping the maintenance reserve, preparing the annual Hausgeldabrechnung (statement of the year's contributions and costs) and organizing the Eigentümerversammlung (owners' meeting).
Is a virtual owners’ assembly allowed under German law?
Yes, under the law of 10 October 2024 (BGBl. 2024 I No. 306), in force since 17 October 2024: owners can resolve by at least a three-quarters majority of the votes cast to hold assemblies without physical presence for at most three years (Section 23(1a) WEG), provided the virtual assembly is comparable to an in-person one in participation and exercise of rights. If the resolution is passed before 1 January 2028, at least one in-person assembly per year is still required through the end of 2028, unless the owners unanimously waive it (Section 48(6) WEG). A simple-majority option to allow electronic participation in an in-person assembly already existed and is unchanged.
Which costs count as umlagefähige Betriebskosten (service charges that can be passed on to tenants)?
Inside a WEG, cost allocation follows Section 16(2) WEG: each owner bears the community’s costs in proportion to their Miteigentumsanteile (co-ownership shares), unless an agreement (typically the Teilungserklärung, the declaration of division) or a resolution under Section 16(2) sentence 2 WEG sets a different key. The Betriebskostenverordnung (service charges ordinance), by contrast, only lists what a landlord may pass through to tenants — the catalog in Section 2 BetrKV covers items such as property tax, water and drainage, heating and hot water, elevator, cleaning, insurance and caretaker (Hauswart) — and it expressly excludes management and maintenance costs (Section 1(2) BetrKV); managers use that catalog only where a unit is let.
Does heating consumption have to be reported monthly?
Only where remote-readable meters are installed. Since 1 January 2022, the Heizkostenverordnung requires monthly consumption information to residents in that case, on top of the annual statement.
What is the difference between Sondereigentum (individual ownership) and Gemeinschaftseigentum (common ownership)?
Sondereigentum is the individually owned unit, the parts an owner can renovate or sell on their own. Gemeinschaftseigentum is everything shared by the WEG: structure, roof, facade, stairwells, and the building’s technical systems, decided on collectively.
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.
