Grant Thornton launches new tool, pairing skilled professionals with powerful AI agents

Proprietary CompliAI^™ tool enhances the sophistication and agility of Grant Thornton’s risk and compliance services

Grant Thornton, one of America’s largest providers of end-to-end audit, assurance, tax and advisory services, announced today the launch of a new, proprietary artificial intelligence solution, CompliAI^™.

CompliAI is part of a broader transformation in how Grant Thornton's professionals help clients control and assess risks and address their most pressing business needs.

Grant Thornton developed CompliAI using Microsoft Azure OpenAI Service, allowing it to operate as a fully integrated web application that enhances and streamlines the compliance process for service delivery teams. The platform uses advanced AI capabilities, including GenAI Assistants and a GPT Model Series.

Grant Thornton’s professionals can now conduct tasks in minutes that would have traditionally taken days or weeks, which means clients can enjoy high quality operational insights more quickly and cost-effectively.

“CompliAI is the beginning of Grant Thornton’s wider adoption of AI and next generation solutions,” said Jim Peko, CEO of Grant Thornton Advisors LLC. “We are seamlessly integrating new technology into daily workflows and using it to make data-driven decisions — while also building AI into a range of services that help clients gain a distinct competitive advantage.”

Peko adds that: “The result will be world class service, further establishing us as the provider of choice for clients and professionals alike.”

“This new tool helps our professionals focus more of their time on meaningful engagement with our clients and provides more rapid insights,” said Mike Kempe, chief information officer of Grant Thornton Advisors LLC. “Our firm is laser focused on giving our people what they need to drive additional value.”

"We are pleased to see Grant Thornton’s successful rollout of CompliAI,” said Brian Willson, vice president at Microsoft. “It’s a testament to the relationship between Grant Thornton and Microsoft. Grant Thornton’s commitment to using Microsoft Azure OpenAI Service is resulting in transformative solutions that increase efficiency, accuracy and value for their clients. This collaboration underscores our shared vision of driving innovation and excellence in the industry."

An intelligent AI agent for every professional

The CompliAI^™ rollout comes as Grant Thornton is actively expanding its use of AI across the full range of functions at the firm, from audit and assurance services to tax and advisory offerings. Integrating new technology into daily workflows helps Grant Thornton drive more sophisticated, personalized and data-driven decision-making to clients.

In May 2025, Accounting Today named Grant Thornton one of its 2025 Best Firms for Technology — citing the “three tiers of [the firm’s] successful technology strategy: application modernization, data centralization and AI integration.”

According to Kempe: “Grant Thornton seeks to seamlessly weave AI into key aspects of our quality-focused service delivery and daily workflows, with platforms like CompliAI serving as an early example. To realize this vision, we are implementing a phased AI maturity model, providing our client service professionals access to AI tools that work with them and enhance their ability to provide proactive insights.”

Jeanna Shapiro, chief people and culture officer of Grant Thornton Advisors LLC, emphasized the focus on empowering Grant Thornton's workforce: “Our people are at the core of our AI strategy. We are dedicated to equipping them with the right tools and training to excel in an AI-driven landscape. By leveraging AI, we help our professionals concentrate on higher-value engagement, foster innovation and deliver superior results for our clients.”

In addition to investments in Grant Thornton’s own AI infrastructure, the firm continues to invest further in supporting clients with their evaluation and implementation of technology and AI-enabled solutions through its Advisory service line.

Tom Puthiyamadam, Grant Thornton’s national managing principal for Advisory Services, commented: “The ever evolving commercial and technology landscape means business leaders need to deploy technology which can unlock new opportunities to drive measurable value as well as make their businesses more resilient. Our technology and AI advisory professionals are well positioned to guide clients along that journey, now with the additional insights from Grant Thornton’s own evolution in AI.”

The firm’s embrace of AI is fueled by its recent growth investment led by New Mountain Capital — and by its recently-created multinational platform, which is expanding to include the U.S., Ireland, the Netherlands, the United Arab Emirates, Luxembourg, the Cayman Islands, and other territories.

“We are big believers in the power of people plus technology and are excited to empower Grant Thornton’s growth with additional investment in the latest technology and cutting-edge AI solutions for the benefit of clients, partners and staff,” added Andre Moura, managing director at New Mountain Capital.
