Mobility Signage, a Munich-based start-up for digital infrastructure in public transport founded in 2023, has closed a €1.8 million pre-seed round. High-Tech Gründerfonds (HTGF) led the round, with 2bX participating as co-investor. The capital will be used to grow the team and accelerate development of the company’s Data Hub and application layer.
Replacing patchwork with a central architecture:
Public transport operators face a dual challenge: decades of fragmented, siloed IT infrastructure collide with rising passenger expectations for real-time information and seamless digital experience.
Mobility Signage tackles this head-on with a central data architecture that integrates existing systems rather than replacing them. As a unified data and integration layer, the platform structures data flows, standardises interfaces, and enables consistent information delivery across every output channel, from departure boards and apps to public address systems
Stefan Rademacher, Co-Founder, Mobility Signage, said: “Transport operators don’t need yet another standalone tool, they need a unifying system logic. We replace the patchwork of one-off solutions with an integrated, scalable platform.”
Dominik Nouri, Co-Founder, Mobility Signage, says: “Our goal is to connect fragmented IT landscapes and create a reliable data foundation for real-time information, without forcing operators to rip out their existing systems.”
Strong traction with Germany’s largest operators:
The platform is already live with a broad range of operators, from regional networks to some of Germany’s largest transit authorities, including Berliner Verkehrsbetriebe (BVG), Stuttgarter Straßenbahnen (SSB), Deutsche Bahn, and Rostocker Straßenbahn (RSAG). The breadth of the customer base demonstrates that the modular architecture scales across operator sizes.
Leading hardware manufacturers have also signed on as development partners, a signal that the open, integrable architecture resonates across the industry. The result: less operational complexity, better passenger information.
Mobility Signage is building a vertical operating system for public transport. Its first modules automate key processes including construction site notifications and real-time disruption management.
A growing market for intelligent transport systems:
The global Intelligent Transport Systems (ITS) market is a multi-billion-dollar opportunity, with bus and tram systems in Europe alone representing a significant and growing segment.
Tizian Hoppen, Senior Investment Manager, HTGF, commented: “Public transport operators are under pressure from skills shortages, ageing IT systems, and growing ridership. Mobility Signage addresses exactly these pain points with a modular, AI-native solution. The team has already proven real-world traction, with some of Germany’s largest operators as customers. The central data architecture is the key to making public transport fit for the future.”
