Professional services firm: accounting, audit, tax, and legal advice across 50+ Netherlands locations

Financial Services Nederland, Nederland 1,001–5,000 employees Public Company

aaff is a 2,000-person professional services firm operating across accounting, audit, tax advisory, and legal services from 50+ locations in the Netherlands. The tech stack reveals a heavy Azure/Microsoft footprint (Data Lake, Synapse, OpenAI, Cognitive Services) paired with Databricks and Collibra—a data-engineering-first approach unusual for traditional Big Four-style practices, suggesting aaff is building internal analytics and governance infrastructure rather than relying on legacy audit/tax software alone. Active hiring in finance and audit roles dominates the department mix, aligned with ongoing due diligence and tax optimization projects.
