Grant Thornton Advisors LLC has completed its transaction to integrate Auxis, a nearshore-outsourcing and business-modernization firm. This agreement, initially announced on July 29, adds over 1,400 professionals from Auxis across Costa Rica, Colombia, and the U.
S. to Grant Thornton Advisors.
Auxis specializes in tech-enabled shared services spanning finance, information technology, human resources, customer experience, and specialized industry solutions. The firm also offers digital transformation services in AI, automation, RPA, Agentic, Analytics, and Cloud. Established in 1997, Auxis was an early provider of nearshoring services to U.
S. businesses, serving a client base that includes Fortune 1000 and upper-middle-market companies. Its solutions have been recognized by organizations such as UiPath, Everest Group, and ISG.
The acquisition supports Grant Thornton Advisors’ strategy to develop an advisory model powered by AI, advanced technologies, and practical innovation. The firm provides services in strategy, transformation, and operations, covering M&A, technology, finance, operations, sales and marketing, data, AI, cybersecurity, and risk, alongside tax services. This deal further strengthens the multinational, multi-disciplinary platform Grant Thornton Advisors established in January 2025, which has seen transactions with multiple full-service accounting and consulting firms across the Americas, Europe, and the Middle East, including the recent acquisition of Stax, a diligence and value-creation provider.
Jim Peko, CEO of Grant Thornton Advisors LLC, stated, “Bringing Auxis into the Grant Thornton platform is a milestone moment for us. Auxis’ proven shared services, nearshoring expertise, and tech-enabled solutions are a natural fit for our world-class model. This deal allows us to deepen client engagement and enhance our offerings — delivered with speed, scalability, and quality.”
Tom Puthiyamadam, Managing Partner for Advisory Services at Grant Thornton Advisors LLC, added, “Clients today aren’t just asking for advice — they want consultants who can deliver bold solutions with agility, smart technology, practical innovation, and quantified impact. That’s why we’re building something truly unique: a full-service advisory practice powered by AI and grounded in human insight. Bringing Auxis into the fold will strengthen that vision. They have the talent, tools, and nearshoring model to help us deliver enhanced value to our clients.”
Raul Vega, CEO of Auxis, commented, “Joining the Grant Thornton team provides Auxis the scalable and robust platform required to successfully help clients modernize their operating models — helping them thrive in a business environment marked by ever-increasing change and technology disruptions. We are excited to integrate our innovative and tech-enabled, client-first services model into Grant Thornton’s leading Advisory Services practice. It could not be a better fit. Grant Thornton’s deep client relationships and reputation for excellent quality will enable us to deliver our value-added, technology-backed services to an even broader international clientele.”
The terms of the deal were not disclosed.
Grant Thornton delivers professional services in the U.
S. through two specialized entities: Grant Thornton LLP, a licensed CPA firm providing audit and assurance services, and Grant Thornton Advisors LLC, which exclusively provides non-attest offerings, including tax and advisory services. In January 2025, Grant Thornton Advisors LLC formed a multinational, multidisciplinary platform. Auxis, headquartered in Fort Lauderdale, Florida, with main delivery centers in Costa Rica and Colombia, and supporting hubs in Mexico and Guatemala, focuses on helping organizations achieve a competitive edge through innovative processes, leading technologies, and shared services.
