PRESS RELEASE

Grant Thornton Advisors completes deal to join forces with Auxis

Firm expands full-service advisory practice; brings Auxis’ modernization services to new multinational markets.

CHICAGO and FORT LAUDERDALE, FLA., Sept. 2, 2025 — Grant Thornton Advisors LLC (Grant Thornton Advisors) has completed a transaction to join forces with Auxis, a nearshore-outsourcing and business-modernization pioneer. 

The transaction, which was previously announced on July 29, brings Auxis’ award-winning automation and outsourcing capabilities to Grant Thornton Advisors, adding more than 1,400 professionals across Costa Rica, Colombia and the U.S.

Auxis specializes in tech-enabled shared services across finance, information technology, human resources, customer experience and specialized industry solutions — as well as digital transformation offerings in AI and automation. It serves a client base that includes Fortune 1000 and upper-middle-market companies.

Founded in 1997, Auxis was one of the earliest providers of nearshoring services to US businesses — offering real-time collaboration, cultural alignment and access to top-tier Latin American talent. Its intelligent automation and nearshore solutions have earned recognition from leading technology providers and research firms, including UiPath, Everest Group and ISG.

The deal supports Grant Thornton Advisors’ strategy to build a differentiated advisory model powered by AI, advanced technologies and practical innovation. The firm currently provides a range of services centered on strategy, transformation and operations. These include offerings across M&A, technology, finance, operations, sales and marketing, data, AI, cybersecurity and risk. Grant Thornton Advisors also provides a complete slate of tax services.

Acquiring Auxis bolsters the multinational, multi-disciplinary platform Grant Thornton Advisors established in January 2025. To date, it has announced transactions with more than a half-dozen full-service accounting and consulting firms to join the platform. These firms stretch from the Americas across Europe to the Middle East. Additionally, it announced a deal last month to acquire Stax, a top diligence and value-creation provider based in Boston with a presence across key financial markets.

Terms of the deal were not disclosed.
