Grant Thornton Advisors Invests $1 Billion to Empower Multinational Workforce with AI-Driven Tools
In a bold move to harness the transformative potential of artificial intelligence (AI), Grant Thornton Advisors LLC is investing $1 billion over three years to equip its multinational workforce with cutting-edge AI tools and technology. This investment will span across its expansive professional services platform, which extends from the Americas through Europe to the Middle East, enabling the delivery of innovative and high-quality accounting, tax, and advisory services. The initiative underscores a people-centric model powered by AI, aiming to drive productivity, enhance client outcomes, and position the firm as a leader in the digital transformation of professional services.
A Strategic Investment in Technology and People
This landmark investment reflects Grant Thornton Advisors’ commitment to building a future-ready technology infrastructure. By integrating advanced systems and tools, the firm seeks to address evolving market demands while fueling organizational growth. The goal is to create a seamless end-to-end digital experience for both its professionals and clients, ensuring that they benefit from the latest advancements in AI and technology.
A key component of this initiative is the rollout of Microsoft 365 Copilot, an AI-powered tool designed to streamline workflows and boost productivity. The rollout builds on an earlier pilot project where 400 professionals within the firm tested the tool, achieving significant productivity gains. Now, all 13,500+ professionals across 60 multinational offices will have access to Microsoft 365 Copilot, allowing them to integrate it with their Grant Thornton data sources and Microsoft apps. This widespread adoption is expected to yield even greater benefits, empowering employees to work more efficiently and effectively.
“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 tools they need to work smarter, faster, and in alignment with their individual styles. When our people are empowered, they deliver their best work, and our clients reap the rewards.”
Mike Kempe, Chief Information Officer of Grant Thornton Advisors LLC, echoed this sentiment: “This investment ensures that everyone at Grant Thornton Advisors, from our newest hires to our most seasoned professionals, has access to AI and technology resources. For example, Microsoft 365 Copilot will help our team save time, manage workloads more effectively, and make more insightful decisions. Ultimately, this means we can provide clients with personalized, high-quality services more efficiently.”
Building a Full-Service Platform Amplified by AI
The rollout of Microsoft 365 Copilot is part of a broader strategy to leverage AI and advanced technologies to enhance service delivery. Tom Puthiyamadam, Managing Partner for Advisory Services in the U.S., emphasized that this effort is one of many steps toward creating a full-service platform amplified by AI and grounded in human insights.
“We’re not just adopting AI tools like Copilot—we’re integrating them into a comprehensive ecosystem designed to solve complex challenges for our clients,” he said. “This is part of a steady cadence of innovations aimed at delivering novel solutions and driving value for our clients.”
Grant Thornton Advisors’ embrace of AI has been bolstered by its partnership with 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 one of the strongest technology-enabled platforms in the accounting profession. The firm is leading the market in developing and deploying AI technologies for the benefit of its clients, and we remain committed to supporting these efforts.”
Progress Through Innovation
Over the past year, Grant Thornton Advisors has made significant strides in implementing a phased AI maturity model across its platform. In May, the firm launched CompliAI™, a proprietary AI solution leveraging advanced capabilities and a custom-trained large-language model to help clients assess and mitigate risks. The firm’s commitment to innovation was further recognized when Accounting Today named it one of its 2025 Best Firms for Technology, citing its successful three-tiered technology strategy: application modernization, data centralization, and AI integration.
Brian Willson, Vice President at Microsoft, praised the firm’s progress: “Grant Thornton Advisors is accelerating its digital transformation journey by deploying Microsoft 365 Copilot across its entire workforce. This demonstrates the firm’s dedication to innovation and its focus on delivering tech-forward professional services. Microsoft is proud to support Grant Thornton Advisors as it embraces AI to empower its people and enhance client outcomes.”
Expanding the Multinational Platform
Since its establishment in January 2025, Grant Thornton Advisors’ multinational, multidisciplinary platform has seen rapid expansion. Transactions have been announced with several full-service accounting and consulting firms across Ireland, the UAE, Switzerland/Liechtenstein, the Netherlands, Luxembourg, the Cayman Islands, and the Channel Islands. These partnerships strengthen the firm’s global reach and expertise.
Additionally, Grant Thornton Advisors recently acquired Auxis, a U.S.-based leader in outsourcing and business modernization services, further enhancing its capabilities. Last month, the firm also announced plans to add Stax, a leading strategy consulting firm specializing in commercial due diligence, value creation, and exit planning for private equity firms, to its platform.
A Future Defined by Innovation and Collaboration
Grant Thornton Advisors’ $1 billion investment in AI tools and technology represents a pivotal step in redefining how professional services are delivered. By combining advanced AI solutions like Microsoft 365 Copilot with a people-first approach, the firm is poised to unlock unprecedented levels of productivity and client satisfaction. As the firm continues to expand its global footprint and deepen its technological capabilities, it remains committed to fostering innovation, empowering its workforce, and delivering exceptional value to clients worldwide.
With AI at the forefront of its strategy, Grant Thornton Advisors is setting a new standard for excellence in the professional services industry—one that blends cutting-edge technology with the human touch.
