Grant Thornton Advisors has finalized its acquisition of Auxis, a nearshore outsourcing and business modernization firm known for its automation and shared services capabilities. The deal, first announced in late July, brings more than 1,400 professionals into Grant Thornton’s advisory ecosystem, expanding its reach across Costa Rica, Colombia, and the United States.
Auxis, founded in 1997, has long been recognized as a pioneer in nearshoring for U.S. businesses. Its model emphasizes real-time collaboration, cultural alignment, and access to highly skilled Latin American talent. Over the years, the firm has built a reputation for delivering tech-enabled shared services across finance, IT, HR, customer experience, and industry-specific solutions. Its digital transformation offerings in AI and automation have earned accolades from leading technology platforms and research firms, including UiPath, Everest Group, and ISG.
This acquisition aligns with Grant Thornton Advisors’ broader strategy to build a differentiated advisory model powered by advanced technologies and practical innovation. The firm offers a wide range of services across strategy, transformation, and operations, including M&A, finance, technology, sales and marketing, data analytics, cybersecurity, and risk management. It also provides comprehensive tax advisory services.
The integration of Auxis strengthens the multinational platform Grant Thornton Advisors began assembling in January 2025. Since then, the firm has announced partnerships with more than half a dozen full-service accounting and consulting firms across the Americas, Europe, and the Middle East. Just last month, it acquired Stax, a Boston-based diligence and value-creation firm with a strong presence in key financial markets.
