Grant Thornton Advisors investing $1B in AI technology rollout
- Grant Thornton Advisors investing $1 billion to arm the multinational workforce across its platform with powerful AI tools and technology
- Rollout of Microsoft 365 Copilot expected to seed significant productivity gains
CHICAGO, September 4, 2025—Grant Thornton Advisors LLC (Grant Thornton Advisors) is investing $1billion over three years to provide powerful AI tools and technology to the entire workforce at its multinational professional-services platform, which stretches from the Americas across Europe to the Middle East. The investment will help the platform deliver innovative and high-quality accounting, tax and advisory services based on a people-centric model powered by AI.
The investment marks a strategic move toward creating a future-ready, technology infrastructure — one built around integrated systems that address market demands and fuel organisational growth. As a result, the multinational platform will be able to deliver a better end-to-end digital experience for both its professionals and its clients.
Grant Thornton Advisors is currently putting its investment into action by providing the more than 13,500 platform professionals in 60 multinational offices with access to Microsoft 365 Copilot. The rollout complements an earlier pilot project that saw Grant Thornton Advisors provide Microsoft’s AI tool to a 400-person cohort of professionals — generating significant productivity gains. It expects to see broader benefits when all of the platform’s professionals, regardless of role, integrate Microsoft 365 Copilot into their Grant Thornton data sources and Microsoft apps.
“This isn’t just about investing in AI and technology, it’s about investing in our people,” said Jim Peko, CEO of Grant Thornton Advisors LLC. “We’re giving every professional across our multinational platform — from Chicago to Dubai — the kinds of tools they need to work smarter, faster and in keeping with their individual styles. The result is something that is uniquely Grant Thornton: People who are empowered do their best work so clients benefit from the quality and results they need.”
Mike Kempe, chief information officer of Grant Thornton Advisors LLC, echoes this sentiment:
“This investment is a big step as we ensure that every person at the Grant Thornton Advisors platform has AI and technology resources at the ready, from our newest hires to our most seasoned professionals. The Microsoft 365 Copilot rollout, for example, will help our people save time, balance their workloads and make more insightful decisions. This means they’ll be able to efficiently provide our clients with personalised high-quality services.”
Grant Thornton Advisors’ managing partner for Advisory Services in the U.S., Tom Puthiyamadam, stresses that the Copilot rollout is one of many moves that will help the firm deliver quality services powered by AI and grounded in human insights.
“We’re building a full-service platform amplified by AI and advanced technologies,” he said. “Investing in tools such as Copilot is a critical next step in this effort and part of a steady cadence of innovations that will help us provide clients with novel solutions to whatever challenges lie ahead.”
Grant Thornton Advisors’ embrace of AI is fueled by its recent investment led by New Mountain Capital, a growth-oriented investment firm with approximately $55 billion in assets under management.
According to Andre Moura and Nikhil Devulapalli, managing directors at New Mountain Capital:
“We are proud to support this major AI investment as Grant Thornton Advisors builds out one of the strongest technology-enabled platforms in the accounting profession. Grant Thornton is leading the market in developing and deploying AI technologies for the benefit of its clients, and we intend to continue supporting these types of investments.”
Over the past year, Grant Thornton Advisors has made notable progress implementing a phased AI maturity model across its platform. In May, it launched CompliAITM, a proprietary AI solution that uses advanced capabilities and a custom-trained large-language model, to help clients control and assess risks. Also in May, Accounting Today magazine named Grant Thornton Advisors one of its 2025 Best Firms for Technology — citing the “three tiers of [the firm’s] successful technology strategy: application modernisation, data centralisation and AI integration.”
According to Brian Willson, vice president at Microsoft:
“Grant Thornton Advisors is accelerating its digital transformation journey by deploying Microsoft 365 Copilot across its platform’s entire workforce. This move reflects the firm’s commitment to innovation and its focus on delivering tech-forward professional services. Microsoft is proud to support the firm as it embraces AI to empower its people and enhance client outcomes.”
Grant Thornton Advisors established its multinational, muti-disciplinary platform in January 2025. To date, transactions have been announced with several full-service accounting and consulting firms to join the platform, including those in Ireland, the UAE, Switzerland/Liechtenstein, the Netherlands, Luxembourg, the Cayman Islands and the Channel Islands.
Additionally, Grant Thornton Advisors recently acquired Auxis, a U.S.-based leader and pioneer in outsourcing and business modernisation services. And, last month, it announced a transaction that will add an additional advisory firm to its platform: Stax, a leading strategy consulting firm specialising in commercial due-diligence, value-creation and exit-planning services for private equity firms, as well as their portfolio companies and advisors.
