We have advised JAN© Accountants & Adviseurs (JAN©), a fast-growing Dutch accountancy and advisory firm, on its sale to de Jong & Laan, a leading accountancy and advisory organisation with a strong national footprint.
Founded in 2005, JAN© has evolved into a high-quality multidisciplinary firm, serving SME and other clients across the west of the Netherlands from its four offices in Schiphol-Rijk, Purmerend, Valkenburg (ZH), and Weesp. The firm employs approximately 160 professionals, including accountants, tax advisers, pension and HR consultants, legal experts, and valuation specialists. Over the years, JAN© has grown both organically and through select acquisitions, building a strong reputation for performance improvement, pragmatic advice, and a personal approach.
With over 975 employees across more than 20 offices, de Jong & Laan is one of the leading accountancy and advisory organisations in the Netherlands. The firm provides accountancy and tax services as well as highly specialised consulting in areas such as corporate finance, IT, HR, ESG, and family business advisory. In recent years, de Jong & Laan has strategically expanded its services and client reach through several targeted acquisitions, including Marshoek, Good Growth Collective, Less Grey, and TIC Advisory.
By joining forces with de Jong & Laan, JAN© is well-positioned to accelerate its ambitions for further growth and professionalisation. The combination offers JAN© access to broader expertise, enhanced digital capabilities, and a larger network of professionals, enabling the firm to further strengthen the quality and breadth of its services. Backed by a partner that shares its values and long-term vision, JAN© will be able to invest more decisively in innovation, talent development, and operational excellence. In addition, the partnership provides a strong platform to continue JAN©’s selective acquisition strategy, allowing the firm to expand its regional presence and scale its impact while maintaining its distinctive client focus.
JAN© will continue to operate under its existing label, supplemented with the tagline ‘Powered by de Jong & Laan’. Andrea van der Giezen, CEO of JAN©, will join the Executive Board of de Jong & Laan as Chief Quality Officer, overseeing the firm’s quality, compliance, and technical standards.
We supported the management team of JAN© in defining the optimal strategic path and identifying the right partner for the next phase of growth. Throughout a focused and hands-on process, we worked closely with JAN© to articulate its strategic priorities, align stakeholder interests, and secure a strong outcome. This transaction demonstrates our deep experience in the professional services sector and our commitment to supporting ambitious firms in realising their long-term objectives through carefully structured partnerships.
