As part of this program, HCLTech, Circles and Greyskies are collaborating with leading telecom operators such as Circles.Life, KDDI, Orange and TELUS to jointly develop a new AI-powered multi- agent framework to unify customer experience, network operations and business processes into an intelligent, real-time operational ecosystem. The new solution is designed to accelerate end-to-end automation, enhance service assurance and improve customer engagement while unlocking new monetization opportunities through AI-driven insights. The initiative combines Circles’ AI-native digital telco platform and customer engagement capabilities with GreySkies’ AI-enabled network operations and HCLTech’s AI-led automation, integrated through TM Forum Open APIs within an Open Digital Architecture (ODA) framework. Together, it enables telecom service providers to analyze customer and network signals in real time, anticipate issues and drive autonomous decision-making across the enterprise. By integrating advanced AI capabilities with open, standards-based architectures, the solution supports the transition to self-optimizing networks that are more responsive to changing customer needs and operational complexities. The approach is intended to improve operational efficiency, accelerate insight-to-action and enhance customer lifetime value. "As service providers look to meet rising customer expectations, AI will play a critical role in delivering more personalized, anticipatory and seamless experiences," said Sanjay Kaul, Chief Revenue Officer at Circles. "Through this collaboration, we are bringing together complementary capabilities to help operators connect customer insights with network and business operations in real time, creating new opportunities for growth and differentiation." "Autonomous operations start with truly understanding the network. By bringing AI-driven observability and assurance into this Catalyst, we are helping operators anticipate and resolve issues before customers ever feel them," said Dr. Ibrahim Ghaleb, Chief Operating Officer at GreySkies. "Together with Circles and HCLTech, we are showing how intelligent network operations connect directly to customer and business outcomes, turning real-time network signals into faster, self-driven decisions across the entire operation." “Inclusion in the TM Forum Catalyst program reflects our commitment to co-innovate with the global telecom ecosystem and accelerate the industry’s transition to AI-driven, autonomous operations,” said Anil Ganjoo, Chief Growth Officer and Global Head of Telecom, Media and Technology at HCLTech. “By bringing together multi-agent AI capabilities with open, standards-based architectures, we are enabling service providers to deliver more intelligent, agile and differentiated customer experiences at scale.” The Catalyst projects will be showcased at TM Forum’s DTW Ignite event in Copenhagen, bringing together industry leaders to explore collaborative innovation and the future of telecommunications transformation.
