Germany’s property management industry has a reputation problem. Slow responses, paper-heavy processes, and hard-to-reach contacts have frustrated property owners for years. A survey of over 120 property owners found that 87 percent were dissatisfied with their current management. That number alone tells you everything about why reltix exists.
Founded in March 2025 by three former classmates from WHU Otto Beisheim School of Management, reltix is a Düsseldorf-based PropTech startup aiming to rethink property management from scratch. The three co-founders are Léon Bamesreiter, Jan Horstmann, and Andreas Plakinger. The motivation was personal. Bamesreiter bought his first apartment at 20 during a dual-degree program at a major bank, and his experience with property managers was one of thick folders, slow responses, and little transparency. “I felt like I was becoming the property manager myself,” he said.
Software Doing the Heavy Work:
The core of reltix is its proprietary software. The system captures incoming emails and WhatsApp messages, automatically creates tickets, reads digital documents, and assigns them to the right processes. It also structures large amounts of data centrally and automatically contacts tradespeople when needed.
This is not a surface-level digitization play. The goal is to automate the background operations so that human property managers can spend more time on-site with clients. Each property gets a dedicated manager who is reachable from 9 am to 8 pm. The bet is that combining automation with genuine human availability is more effective than either approach alone.
reltix also offers a compact management product for smaller properties. For owner communities with three to eight units, this includes legally compliant accounting, the organization of owner meetings, and coordination of larger renovation projects, while everyday tasks remain with the owners themselves. It is a lighter-touch tier designed for smaller portfolios that do not need full-service management but still require professional oversight for legal and financial obligations.
2,000 Customers in Under a Year:
The growth numbers are notable for a startup less than a year old. reltix has reached 2,000 customers since its March 2025 launch. Much of that momentum came at the end of 2025. Many property management contracts in Germany end on December 31, and accounting deadlines pile up at the same time. In the final weeks of 2025, reltix added 500 mandates in a short period, including new-build projects in Langenfeld and Cologne. Several banks, family offices, and larger private property holders now count among its clients.
The startup manages more than 2,000 apartments and currently employs between 10 and 20 people. To keep up with demand, the team grew from 14 to 17 employees by February 2026.
Research Funding and Expansion Plans:
The team has been recognized for its technical approach. reltix received approval for a research grant from Germany’s Federal Ministry for Research, Technology, and Space, with a project budget of 1.3 million euros allocated for further development of the company’s software.
The startup is also a certified vocational training company under Germany’s IHK system, the national chamber of commerce network that sets official standards for workplace apprenticeships. While traditional property management firms struggle to attract new talent, reltix actively recruits young staff, career changers, and trains its own. A former mechanical engineer now leads rental management, and a former bank employee works in accounting.
On the geographic side, reltix is focused on the Rhine-Ruhr region and Cologne-Bonn corridor today. Frankfurt is next, with a new office planned for summer 2026. Düsseldorf will remain the company’s headquarters.
A Real Problem with Real Scale:
The property management sector in Germany is genuinely large and genuinely broken. Millions of apartment owners interact with property managers regularly, and the dissatisfaction rate documented by reltix’s own research points to a durable market opportunity in digital property management (Hausverwaltung).
reltix is not trying to simply digitize old processes. The platform it is building automates the operational work so that managers focus on what actually requires a human. That is a meaningful product distinction in a space where most competitors have barely moved past email.
For founders and operators watching the German PropTech space, reltix is a clear example of a startup attacking a well-defined pain point with a concrete product, real customer numbers, and research-backed software development.
