Solimas Groep

What Solimas Groep does

Interstellar Group B.V. is a Dutch IT services company headquartered in Delft, Netherlands, operating as a private limited company (B.V.) with approximately 700 specialist employees serving enterprise and mid-market clients across the Netherlands. The company delivers managed IT services organized around four expertise pillars: Workspace & Collaboration, Cloud & Infrastructure, Security & Compliance, and Data & AI. Its product portfolio spans Managed Microsoft 365, Teams Phone business telephony, Intelligent Workspace, Soevereine Cloud (Sovereign Cloud hosted in own Dutch data centers), Azure Public Cloud and Hybrid Cloud managed services, Infrastructure as Code, and a full security stack including SOC, MXDR, Endpoint Security, Network Security, Identity Management, Data Security, and CISO as a Service. Vertical-specific solutions include Digitale Zorgwerkplek (Digital Healthcare Workspace) and BIM Workspace for construction firms.

The underlying technology stack is anchored to the Microsoft ecosystem (Microsoft 365, Azure, Teams, Power Platform, Copilot Studio, Azure AI Foundry, Microsoft Fabric, Power BI) with proprietary Dutch-hosted cloud infrastructure that provides data sovereignty unavailable from hyperscaler-only providers. Interstellar holds ISO 9001, ISO 27001, NEN 7510 (Dutch healthcare information security), and B Corp certifications, positioning compliance as a primary differentiator in healthcare and public sector procurement.

The business model combines recurring managed services contracts (managed Microsoft 365, Azure cloud, SOC/MXDR) with project-based professional services and consulting for cloud migration, security compliance, and Data/AI engagements. Go-to-market is enterprise field sales supplemented by an inside sales team and customer portal (support.interstellar.nl), with channel partnerships including Microsoft and PLTFRM. Pricing is bespoke with annual billing and no public price list. Customer segments are weighted toward regulated verticals in the Netherlands: healthcare (Pieter van Foreest, Onze Huisartsen, Santeon MST), construction (Dura Vermeer, BOZ Group), and government (Gemeente Lansingerland), with expansion into manufacturing enterprise clients.
