Buy & build strategy

Since securing the investment from Waterland in 2022, our organisation has made great strides. Waterland supports us in realising our growth ambitions, and broadening and improving our services. As we pursued further growth, we joined forces with three more organisations in 2023: Marshoek, 5BAR assurance, and Horlings.

Buy & build strategy

After securing the investment from Waterland, we’ve added new offices and employees in Utrecht and Amsterdam, marking a major step toward full national coverage. At the same time, we've strengthened our services by expanding our (international) audit teams, tax services, and financial retail expertise.

Culture plays a crucial role in our buy & build strategy, as does the desire to broaden and deepen our services. The way we work (our quality-driven approach) and the kind of people we bring on board must align with who we are. We’re known for our down-to-earth, no-nonsense culture, and we intend to keep it that way.
