German proptech startup founded in 2025, offering AI-native property management for WEG, rental and commercial properties across Germany, built around its centrix operating system.
reltix GmbH is a German proptech startup founded in 2025 that applies an AI-native operating model to property management across Germany. The company manages homeowners' associations (Wohnungseigentümergemeinschaften), rental properties and commercial properties, replacing paper-based processes with automated, transparent workflows. It is headquartered in Düsseldorf, with a presence in Essen and Frankfurt, and employs more than 30 people.
At the centre of the business is centrix, an AI-powered operating system intended to serve as the central nervous system for all property operations. The system is designed to enable sub-24-hour response times, transparent processes and proactive rather than reactive management. Technical work spans AI-powered operating systems, proptech software, property-management automation, process automation and real estate technology infrastructure.
The company reports more than 4,000 residential units under management and reached €1 million in annual recurring revenue in under a year of operation. It raised €3 million in pre-seed funding, with backing from Tenity and Grunderfonds Ruhr.
