Flatie is a digital platform for managing residential buildings — for managers, co-owners’ representatives and co-owners. We build it in Zagreb, for Croatian buildings and Croatian law.
What we do
Managing a building in practice means notices taped to the front door, defects reported by phone, votes collected flat by flat, and a reserve fund a co-owner sees once a year. Flatie keeps all of it in one place — on a phone, with a record of who published what and when.
The platform brings together 13 tools: a digital notice board, defect reports, online voting with automatic majority calculation, chat, reserve-fund visibility, documents, a calendar, house rules, roles and permissions, and an AI assistant. It is available as a web app and as an iOS and Android app.
Why Flatie exists
Croatia’s building management act, in force since 1 January 2025, imposes obligations that are hard to meet on paper: an annual co-owners’ meeting, reports on fixed deadlines, decisions carried by a majority of ownership shares, and records that have to survive scrutiny.
Flatie was built against that framework — not as a generic building app with Croatian law bolted on afterwards.
How we handle data
All data is stored on servers in the European Union, encrypted. Documents are held in cloud storage (Cloudflare R2).
Access is governed by roles: each user sees only what they are authorised to see, and a co-owner’s personal data is visible only to those who need it for their role. Every co-owner controls their own visibility in chat.
