Grant Thornton, a brand in professional services, and Auxis, a company in Latin American outsourcing and business modernization services, will join forces.
By acquiring Auxis, Grant Thornton aims to enhance its advisory services entity: U.S.-based Grant Thornton Advisors, which provides a range of services centered on strategy, transformation and operations.
The transaction is another important step as Grant Thornton creates a full-service advisory offering, amplified by AI and advanced technologies. Clients will have access to Auxis’ tech-enabled nearshore-outsourcing services, which span finance, information technology, human resources, customer service and specialized industry solutions.
With Grant Thornton, Auxis hopes to deliver a significantly broader portfolio of services with a truly multinational footprint.
The transaction will complement the growth of the Grant Thornton Advisors multinational platform. In recent months, Grant Thornton Advisors has announced transactions with several firms to join the platform, including firms in Ireland, the UAE, Switzerland/Lichtenstein, the Netherlands, Luxembourg, the Cayman Islands and the Channel Islands.
“Bringing Auxis into the Grant Thornton platform is a milestone moment for us,” Jim Peko, CEO of Grant Thornton Advisors, said. “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.”
“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,” Tom Puthiyamadam, managing partner for advisory services at Grant Thornton Advisors, said. “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.”
The deal with Auxis will expand the Grant Thornton platform’s footprint by adding Auxis’ more than 1,400 multilingual team members primarily located in Costa Rica and Colombia — with headquarters in Fort Lauderdale.
“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,” Raul Vega, CEO of Auxis, said. “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.”
Vega will become a member of the leadership team for Advisory Services at Grant Thornton, reporting to Puthiyamadam. Auxis’ existing leadership team will continue to oversee operations for its current client base.
The deal is subject to standard closing conditions. It is expected to close later this year.
