What Wilken Software Group does

Wilken Software Group is a privately held German enterprise software provider founded in 1977 and headquartered in Ulm, with approximately 660-700 employees across offices in Ulm, Greven, Munich, Oldenburg, Dortmund, and Bielefeld. The company develops ERP and billing software for four regulated verticals in the German market: utilities (ENER:GY, GY Billing), healthcare and social services (NTS.suite), church administration (P/5), and tax/enterprise consulting (Wilken Tax). Its technology stack spans both established on-premise ERP suites and the new GY cloud-native platform, which unifies the product portfolio on a shared architecture. Notable technical components include the GY platform, the GY:PT AI assistant, the AIVA voicebot for care triage, and a Data Service Center that operates 350+ ERP instances for 100+ customers.

The company's go-to-market is direct enterprise sales into regulated German institutions, supported by a partner network and recurring customer events (e.g., the Wilken Utility Summit). Revenue is generated through recurring SaaS subscriptions, managed services (the Data Service Center), professional services for implementation and customization, and training. Wilken processes 80% of end-customer contracts in Germany through its platforms, with a customer base including 400+ utilities, 30 German dioceses, and 15 million health insurance members. Its certifications include ISO 27001 and NIS2 compliance, alongside domestic regulatory adherence (GoBD, DSGVO, GWG, AS4, UTILMD, GPKE). The company invests approximately EUR 10 million annually in R&D and was named ERP-System des Jahres 2025 in the energy industry category.

Others

• PRODYNA (NTT Data Business Solutions): German system integrator and managed services provider delivering cloud-native enterprise applications. Adjacent rather than direct peer — they implement and operate platforms including those competing with Wilken in the German midmarket.

Direct peers

• SOPTIM AG: German vendor offering IT solutions for utilities and energy market participants, including metering, grid operation, and market communication. Closely comparable to Wilken's utility-centric product portfolio.
• SIV.AG: German software provider focused on utility billing, energy data management, and market communication for municipal and regional utilities. Competes directly with ENER:GY and NTS.suite in the regulated German energy market.
• Schleupen AG: German vendor specializing in ERP and billing software for energy utilities and municipal utilities. Most direct competitor to Wilken in the Versorgungswirtschaft vertical, with overlapping product positioning around utility billing and market communication.

Emerging players

• epilot GmbH: Cologne-based SaaS platform for utility customer, partner, and product lifecycle management. A GY ecosystem partner but also a potential cloud-native disruptor for utility CRM and customer portal functionality.
• KISTERS AG: German provider of energy data management, forecasting, balancing, and trading software. While a Wilken GY ecosystem partner, KISTERS directly competes with parts of Wilken's energy data management surface area.

Broad incumbents

• Arvato Systems (Bertelsmann): German IT services and software provider serving regulated industries including energy, healthcare, and public sector. Provides competing ERP-style solutions and managed services overlapping with Wilken's Data Service Center.
• Datev eG: Large German cooperative providing software and services for tax advisors, auditors, and healthcare/social insurance organizations. Overlaps with Wilken's P/5 footprint in social services and SHI administration.
• Microsoft (Dynamics 365): Global cloud ERP/CRM suite increasingly used by German midmarket and public-sector organizations. Lacks Wilken's vertical-specific utility/SHI compliance depth but offers a strong cloud-native alternative for general ERP workloads.
• SAP SE: Global ERP leader with significant presence in German utilities, healthcare, and public sector via SAP S/4HANA and industry-specific extensions. Competes with Wilken for large enterprise ERP deals while lacking Wilken's depth in German utility Marktkommunikation and SHI billing.
