What ISO Software Systeme does

ISO Software Systeme GmbH is the core entity of the privately held, owner-managed ISO-Gruppe, a German IT services group founded in 1979 and headquartered in Nuremberg. The group operates through four wholly owned subsidiaries — ISO Travel Solutions GmbH, ISO Professional Services GmbH, ISO Public Services GmbH, and ISO Recruiting Consultants GmbH — and serves approximately 740 employees across offices in Germany, Austria, Poland, and Canada. Its core technology stack spans MACH architecture (Microservices, API-first, Cloud-native, Headless) for travel solutions, object-oriented analysis, agile software development (Scrum, Kanban), blockchain (Camino via Chain4Travel), and AI/ML applied to medical imaging and travel optimization, with deep systems-integration expertise across SAP, Atlassian, Oracle, and Microsoft.

The company runs a hybrid business model combining proprietary packaged software, custom software development, and IT consulting across six vertical business units: aviation (SKYport airport management suite, SKYfly airline revenue accounting, SKYfly Charter for NDC/ONE Order, One Record Hub for air cargo), tourism (Pacific and Atlantic reservation and dynamic packaging systems, FastSearch cache-based search, Internet Booking Engine, Travel Broker supplier connectivity hub, Travel Tailor AI recommendations, Travel:up Video, and the Dynamic Travel Components MACH platform), data quality (Marlin Duplicate Check, Marlin VAT ID Check, Marlin Securities — all SAP-certified on S/4HANA Cloud), public administration, automation (Siemens TIA Portal development), and medical technology (custom CT and angiography software for Siemens Healthineers, biomedical image analytics, and big data analytics).

Revenue is generated through five streams: custom software development (professional services), IT consulting (SAP, Atlassian, Oracle, NIS2 readiness), managed services and hosting (ISO 27001-certified via ISO Professional Services), proprietary software products sold under subscription or license (SKYport, SKYfly, Marlin, Pacific/Atlantic), and IT recruiting services. Distribution is enterprise field sales with dedicated sales managers per business unit, supplemented by direct enterprise inquiry via website demos and channel leverage through the IATA partnership network. Long-tenured enterprise clients include Fraport, Condor, Albrecht Dürer Airport Nuremberg, LEGOLAND Germany Resort, Merlin Entertainments, DER Touristik, Wikinger Reisen (25-year relationship), Jungheinrich, Marc O'Polo, duagon, Witron, TÜV Rheinland, Siemens Healthineers, and the German Federal Employment Agency.
