What Sia Consulting GmbH does

Sia Consulting GmbH is a privately held German consulting firm headquartered in Düsseldorf that delivers professional services across six interconnected lines: cloud consulting (primarily Microsoft Azure with AWS and Google Cloud support), AI consulting and integration, digitalization and process automation, custom .NET and cloud-native software development, GDPR-compliant data security architecture, and corporate training. The technical foundation is built on the Microsoft ecosystem — Azure, .NET/C#, ASP.NET Core, Blazor, TypeScript, Angular, React, Docker, Kubernetes, PostgreSQL, and SQL Server — combined with Clean Architecture, TDD, and DDD development methodologies. The company's AI capabilities span prompt engineering, GPT integration, MLOps, data platform construction, and production deployment, delivered as consulting engagements rather than as a packaged software product. Sia Consulting is a Microsoft Partner and its founder Siavash Ghassemi holds the Azure AI MVP designation, supporting credibility in enterprise Azure deals.

The firm operates a professional services revenue model with quote-based, multi-year contract engagements, augmented by a separate training sub-brand at sia-trainings.de that productizes workshops for C-Level and IT Leadership audiences. Its GTM combines direct enterprise field sales, a free initial consultation funnel, Microsoft Partner co-selling, and demand generation through developer community events such as DevConf.NRW and Barcamp 2026. The named customer base includes over 15 disclosed logos spanning financial services (Volkswagen Bank GmbH), utilities (RheinEnergie AG, Schleupen SE), manufacturing (Festool GmbH, PERI Vertrieb Deutschland GmbH & Co. KG), technology (SoftwareONE Deutschland GmbH, Microsoft Corporation, regio iT), and other verticals, with the company claiming 50+ active customers across 5+ countries. The named core team is small — five individuals plus an external talent pool of 1,000+ professionals — implying delivery is largely subcontracted through the talent network rather than performed by a large internal headcount.
