Information Services Nieuwegein, Utrecht 51–200 employees Privately Held

TDA Group builds data products focused on improving customer data quality and accessibility for enterprise clients. The stack is Microsoft-heavy (.NET, C#, SQL Server, Azure) paired with Angular and Python, reflecting a mature B2B SaaS operation. Active projects signal a transition from legacy on-premise software toward cloud: SaaS architecture renewal, no-code platform development, and API realization are in flight alongside a migration from on-premise to Azure. Sales hiring (4 open roles) outpaces engineering (3), and pain points cite 'closing deals instead of chasing quotes,' indicating a shift toward enterprise deal velocity.
