Annual awards honor technology and business service providers delivering highest levels of customer service to enterprise clients

LONDON--(BUSINESS WIRE)--

Information Services Group ( III ) , a global AI-centered technology research and advisory firm, has named Capgemini, HCLTech and Hexaware as Client Champions, the top overall honor in the 2025 ISG Star of Excellence Awards™, recognizing the three service providers for consistently demonstrating the highest standards of customer service excellence in the past year, based on direct feedback from enterprise customers.

The providers were honored in the eighth annual ISG Star of Excellence Awards for earning the highest cumulative customer experience scores across all regions, industries and technology areas. The awards were presented at the ISG Sourcing Industry Awards gala dinner on November 19, at the conclusion of the ISG Sourcing Industry Conference at the Fairmont Windsor Park London. The title of Client Champion, formerly called the Overall Award, celebrates the companies that best exemplify outstanding service provider customer experience (CX).

The ISG Star of Excellence Awards, part of the ISG Provider Lens® research program, is the premier industry recognition for the technology and business services industry. Providers are ranked on the quality of their services based on direct feedback from enterprise customers in the areas of Business Continuity and Flexibility; Collaboration and Transparency; Execution and Delivery; Governance and Compliance; Innovation and Thought Leadership, and People and Cultural Fit.

The winners are chosen from among a group of more than 240 service providers that ISG analyzes and evaluates each year. This year, ISG received feedback from enterprise clients with roles in IT, operations, lines of business, procurement and vendor management and other areas, operating in the Americas, EMEA and Asia Pacific.

In addition to the Client Champions, last night’s ceremony recognized winners across a wide range of award categories, including:

Excellence Awards, for the highest CX scores across a given category. Persistent Systems received the AI & Data Excellence Award, formerly called the Emerging Tech Award. Coforge won for IT Outsourcing (ITO), Infosys for Business Process Outsourcing (BPO), HCLTech for Ecosystem and Capgemini for highest score across industries. ANSR won the newly introduced Global Capability Center (GCC) Excellence Award.

Excellence Regional Awards, for the top CX score in each region, went to EY for the Americas, Capgemini for EMEA and Cognizant for Asia Pacific.

CX Partnership Awards went to Network Science for Innovation Excellence and Konecta for Delivery Excellence.

Capgemini received the most awards across all categories, with three, followed by HCLTech with two.

John Boccuzzi Jr., president of ISG Research, noted that growing enterprise participation in the ISG Star of Excellence™ program continues to increase its value to providers.

“As more enterprises engage with the ISG Star of Excellence™ program, it’s clear that providers and their clients are doubling down on customer experience as a strategic priority,” Boccuzzi said. “The results give detailed insights into how companies perceive their provider partners. Enterprise feedback on the providers they nominate expands ISG’s knowledge of the industry, strengthening our research and sourcing advisory services.”

Namratha Dharshan, chief business leader of ISG Provider Lens Research, who oversees the ISG Star of Excellence program, said providers are increasingly important to clients’ technology strategies as AI becomes essential for competing in any industry.

“Enterprises continue to demand more from providers even as some AI deployments begin to scale up and deliver operational benefits,” Dharshan said. “They seek partners that can help them execute on a long-term vision while increasing agility to adapt to new technology and business needs.”

The ISG Star of Excellence™ CX research program scores and ranks providers based on customer survey responses. Ongoing surveys ask enterprises to rate their experiences with hundreds of IT and business services providers across industries, regions and technologies. The research goes beyond general satisfaction to explore, in depth, customer experiences with specific services and solutions offered by providers — research that is tied directly to ISG Provider Lens® quadrant evaluations.
