What Seven2one does
Seven2one Informationssysteme GmbH is a Karlsruhe, Germany-based software and services company founded in 2001 as a spin-off of the University of Stuttgart. The company exclusively serves the energy sector (Energiewirtschaft), developing custom data and process models for utilities, grid operators, energy traders, and energy service companies across Germany, Austria, and Switzerland. With 120+ customers spanning all market roles of the energy value chain and 50+ productive systems in operation, Seven2one functions as a full-service partner rather than a pure software vendor.\n\nThe company's core offering is Questra®, a proprietary, cloud-native platform technology organized in three layers: (1) Web-Frontends & Konnektoren, providing a browser-based UI with native connectors to Microsoft Power BI, Microsoft Excel (via the TechStack Analyst Add-in), and Python/R scripting packages; (2) an Integration Layer & Standard Services built around a central GraphQL endpoint, integrated SSO via Authentik or Microsoft Entra ID, and HAKOM PowerTSM® for high-performance energy time-series processing; and (3) Infrastructure & CI/CD based on Kubernetes-managed Docker containers hosted in Germany with Grafana-based monitoring. The platform processes approximately 1,700 daily data imports and 250 daily calculations, managing 55,000 time series comprising 55 billion individual values across customer deployments, and powers use cases including sales controlling, market data management, multi-tenant virtual power plant aggregation, and exchange/billing validation.\n\nSeven2one operates a quote-based, enterprise go-to-market with no public pricing. Revenue is generated through three streams: (1) professional services covering consulting, conceptual design, and agile sprint-based software development; (2) managed services and Questra® platform licensing, including cloud hosting, DevOps, monitoring, and ticket-based support under multi-year contracts; and (3) an 'Expert as a Service' offering for on-demand sparring. The company was acquired by DVV (DVV-Gruppe) in 2024 and maintains ISO 9001 and ISO 27001 certifications. It is led by Managing Directors Dr. Joachim Wittinghofer and Jan Marco Heinz.
