What 4Dotnet does
4Dotnet bv is a Dutch IT consultancy and staffing firm specializing exclusively in the Microsoft.NET ecosystem. Founded and headquartered in Meppel, Netherlands, with a second office in Nieuwegein, the company employs approximately 60 developers, engineers, and architects and operates as a Microsoft Learning Partner. Its core offering comprises three interconnected services: Consultancy (expert advisory including the fixed-fee €1,500 QuickScan), Detachering (placement of skilled.NET developers into client teams on multi-month contracts), and Training (Microsoft certification-aligned programs). The company has expanded its portfolio with AI & Data consulting services focused on data governance, AI implementation, and Azure data platform design using Azure Databricks and Microsoft Fabric.
The company's technology stack is anchored in Microsoft.NET, C#, ASP.NET Core, Blazor, Entity Framework Core, Azure cloud services, Azure Databricks, Microsoft Fabric, and Azure DevOps. Notable client engagements include a near 8-year consultant embedded at Randstad for ASP.NET MVC migration and microservices architecture, a cloud migration of SnelStart's accounting platform enabling 120,000 administrations in Azure SQL with multiple daily releases, and full cloud modernization for Moditech's emergency responder safety system. The firm serves clients ranging from startups to large multinationals and government bodies across HR, accounting, vehicle safety, certification, recruitment, CAD/BIM, and cloud logistics sectors.
4Dotnet generates revenue through professional services billing, primarily via detachering engagements (day-rate or monthly contracts), fixed-fee consultancy projects, and training programs. Distribution is direct, through enterprise field sales and inbound website/phone contact, supplemented by event-driven demand generation (Move Up with 4Dotnet, Tech Leaders, Techorama, Azure Lowlands). The firm is privately held with no disclosed parent company, external investors, or funding rounds. It has been recognized as a World-class Workplace for three consecutive years (2023-2026) by Effectory and counts multiple Microsoft MVPs on staff.
