Grant Thornton Advisors welcomes 1,200-strong Poland member firm to its network
Continuing its expansion around the world, Grant Thornton Advisors has added the network’s Polish business to its ranks, welcoming more than 1,200 accountants and advisors.
The Polish business of Grant Thornton generates annual revenues of around $70 million and provides a wide range of services in the areas of audit, accounting, consulting, tax, financial advisory, and technology. The firm has grown strongly over the past decade, tripling its headcount and increasing its revenues fivefold through a combination of organic and M&A-driven growth.
“Poland is one of Europe’s most resilient and rapidly evolving economies, with a range of thriving industries and an appetite for sophisticated services,” said Jim Peko, CEO of Grant Thornton Advisors. “Making Grant Thornton in Poland part of the platform will allow us to bring new levels of integrated service and quality to Central and Eastern Europe.”
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 platform. The network now has 14 firms, eight of which are based in Europe – the Grant Thornton firms in Ireland, France, Spain, Netherlands, Belgium, Luxembourg, the Channel Islands, Switzerland (and Liechtenstein).
Outside of Europe, Grant Thornton Advisors earlier this month acquired the network’s Brazilian member firm, and this year closed a few acquisitions in the US, including strategy consultancy Stax.
“The Poland business is an ideal addition to our already impressive European footprint,” said Steve Tennant, CEO for Europe, the Middle East and Africa at the Grant Thornton Advisors. “By adding the Polish firm, we’ll expand our ability to deliver seamless, borderless solutions, all while strengthening our position in the region and reinforcing our commitment to helping clients navigate complexity with speed, scale and quality.”
Financial terms and conditions of the deal have not been disclosed.
According to Tomasz Wróblewski, CEO of Grant Thornton in Poland: “The multinational platform we are joining creates unprecedented opportunities – both for us and for our clients. Through this collaboration, we gain access to advanced technological solutions, many powered by AI. And this is precisely what our employees and clients expect from us.”
“Moreover, a consistent and fully integrated platform offers clients even better cross-border service and provides our employees with opportunities for development in a multinational environment.”
