What Perpetuum Mobile does

Perpetuum Mobile d.o.o. is a Zagreb-based Croatian IT software and services company founded in 1989 that designs and delivers custom digital solutions, predominantly for government ministries and public-sector agencies in Croatia. Its portfolio spans document management systems built on Microsoft SharePoint, IT help-desk platforms, environmental waste-tracking systems, and a Water Information System (WIS/VIS) that integrates real-time hydrological data from approximately 500 measuring stations for Croatian Waters (Hrvatske vode). The firm's consumer-facing assets include the Vodostaji mobile application (Android/iOS, React Native) that monitors river water levels for citizens and the Hendrix web application on Microsoft Azure that processes radar sensor data from the Sava River for flood protection.

Technology is anchored in the Microsoft stack — .NET, SharePoint, and Azure — supplemented by PHP/Laravel, React Native, and Firebase Cloud Messaging for mobile push notifications. Through a 2024 Esri partnership (facilitated via GDi, the regional Esri distributor), Perpetuum layers geospatial and Arc Hydro capabilities into its water-resource and infrastructure offerings. The company also operates a proprietary iSite Content Management System, originally built in 2000, and applies machine-learning techniques (LSTM, GRU, Random Forest) to hydrological and meteorological time-series data for flood prediction and digital-twin river modeling. It holds ISO 9001 and ISO 27001 certifications, is GDPR-compliant, and processes personal data under EU data-protection law.

The business operates as a project-based professional services firm: revenue is generated through bespoke development contracts, consulting, and integration work sold directly to enterprise and government clients via consultative sales. Pricing is quote-based and not publicly disclosed; every engagement begins with requirements workshops and functional specification development, followed by development, testing, deployment, and ongoing technical support. The company has no disclosed external funding, no institutional investors, and is wholly founder/management-led. Its stated equity is EUR 37,190 (paid in full), and disclosed contract values (e.g., HRK 384,793.75 for an EU co-financed ISO implementation) indicate a small-scale operation, consistent with the reported 11–50 employee headcount.
