What HLB Witlox Van den Boomen does
HLB Witlox Van den Boomen was a Dutch accounting and advisory firm founded in 1950, headquartered in Waalre, Netherlands, serving entrepreneurs, professionals, high-net-worth individuals, investors, and socially engaged entities across the Midden (Central) region. Its core offerings spanned accountancy and business advisory, audit and assurance, tax advisory, corporate finance, legal advisory, payroll and HRM, estate planning, ESG and sustainability, subsidy advisory, and international business services. The firm operated on a relationship-based, sales-led model with dedicated account managers delivering multidisciplinary engagements under quote-based pricing typical of the Dutch professional services market.
On April 15, 2024, HLB Witlox Van den Boomen merged with PKF Wallast (regio West) and Koenen en Co (regio Zuid) to form Newtone B.V., a unified advisory and accountancy platform. The combined entity operates from 12 locations across Limburg, Noord-Brabant, and the Randstad, employing approximately 1,100 people. Post-merger, the firm extended its capabilities through a strategic partnership with PKF BOFIDI (cross-border Netherlands-Belgium advisory) and absorbed Legent to strengthen wealth protection services for HNW clients. Revenue is generated entirely through professional services fees; the firm is privately held by the combined partner group with no external institutional or PE investment, and no AI-native technology platform is disclosed.
