MANNHEIM/HAMBURG, February 12, 2026 - A new era in asset management begins for Mannheim-based Properium GmbH. The company has announced the successful completion of the digital transformation of its operational processes. At the heart of this realignment is the implementation of Tower360’s real estate management software. With this move, Properium is eliminating previous structural gaps in data processing and establishing a seamless digital workflow for its entire portfolio, which currently comprises over one billion euros in Assets under Management (AUM).
From Excel Sheets to a Digital Value ChainThis step marks a significant departure from conventional management methods. Instead of relying on fragmented standalone solutions and manual spreadsheets, Properium now bundles all data points—from operational management to strategic reporting—within a single, cloud-based environment. The result is a massive increase in data integrity and operational speed.
Stefan Hoeflich, Managing Director of Properium, describes the transformation:
"Before Tower360, we worked with various disparate systems. This led to media disruptions and redundant data maintenance. Tower360’s integrated platform now allows us to centrally manage all property management processes – from operational farming to client reporting. This not only yields efficiency gains but also provides us with a sustainable competitive advantage."
A Leap in Quality for ClientsTechnological consolidation directly supports the service promise made to clients. Customers benefit from a new level of transparency, as information is now available from a single source of truth and processes interlock without delay.
Ralf Schwalenberg, also Managing Director at Properium, emphasizes the client benefits:
"As a property manager, thanks to Tower360, we can offer our clients fully digital processes from day one. From the onboarding of new mandates to ongoing reporting – everything is digital from start to finish. This creates transparency and efficiency, clearly setting us apart from competitors who often still rely on Excel and manual processes."
A Technology Partnership of EqualsThe choice of Tower360 as a technology partner was a deliberate decision for a scalable solution capable of flexibly supporting Properium's planned growth.
Chakra Banerjee, Co-CEO and Co-Founder of Tower360 GmbH, adds:
"Our application is designed to provide our clients with a sustainable competitive advantage by digitalizing processes end-to-end and centralizing all asset-relevant data on one platform."
Julian Vogel, Managing Director of Tower360 GmbH, on the cooperation:
"We greatly value the trust-based collaboration with Properium and are pleased to work with such a strategically thinking and future-oriented partner. The goal of our partnership is to provide long-term support for Properium’s continued growth and to establish the foundation for a lasting competitive edge."
The successful implementation forms the basis for Properium's further expansion and ensures the scalability of its services as a reliable interface between owners, tenants, and service providers.
