Grant Thornton businesses in France, Spain and Belgium join global platform
Grant Thornton Advisors, the company’s private equity backed global platform, has expanded with the addition of Grant Thornton’s member firms in France, Spain and Belgium.
The latest expansion by Grant Thornton Advisors sees the total number of member firms that have joined the platform grow to 11. Its footprint has grown to around 14,000 professionals working across almost 60 offices in the Americas, Europe, the Middle East, and Asia.
Established in January 2025 by the US and Irish wings of Grant Thornton, backed by a New Mountain Capital-led investor group, Grant Thornton Advisors has the ambition to become a leading, global accounting, tax and advisory group, underpinned by exceptional quality and our one-of-a-kind culture. “We set out to build something bold and that’s exactly what we’re doing,” said Jim Peko, CEO of Grant Thornton Advisors.
In France, Grant Thornton is one of the larger accounting and advisory firms with 2,800 employees across 24 offices. The Spanish business has nearly 900 professionals across 10 locations, while the Belgian arm has around 250 professionals.
Commenting on the joining of forces, the leaders of the three businesses said:
Adam Nicol, president of Grant Thornton in France: “France is one of the most active, rapidly evolving business markets on the continent – making this the ideal moment for our firm to execute our own transformation. Committed to quality and a truly unified approach, we are poised to rapidly accelerate our scale in Europe and deliver differentiated multidisciplinary offerings to our broad client base.”
Ramón Galcerán, president of Grant Thornton in Spain: “Our team is very excited to be joining this multinational platform, which has already demonstrated clear benefits for its constituent firms. We look forward to dramatically enhancing our growth strategy with unparalleled access to technology, insights and capital at scale.”
Leslie Van den Branden, managing partner of Grant Thornton in Belgium: “Joining this powerhouse platform marks a strategic step forward for our firm. It strengthens our ability to deepen global collaboration while remaining deeply connected to our local clients. Above all, it enables us to further invest in our people and our clients, and the technologies that strengthen our capabilities and empower our teams.”
Advisory growth
In recent weeks, Grant Thornton Advisors has also announced transactions to enhance its advisory offerings. These include Auxis, a pioneer in outsourcing and business modernization services, and Stax, which specializes in commercial due diligence and value creation.
Meanwhile, the German wing of Grant Thornton recently picked Cinven as its growth partner.
