OneCognizant (1C): Multi-Agent AI Platform for 350,000 Employees

Cognizant deployed one of the largest enterprise multi-agent AI systems industry-wide — OneCognizant (1C) — transforming the digital workplace for its 350,000 employees globally. Built using the Cognizant Neuro AI Multi-Agent Accelerator (neuro-san), 1C integrates hundreds of enterprise applications and proprietary AI agents into a single, AI-powered digital front door. The platform unifies HR services (leave applications, seating, transportation, hardware/software requests via ServiceNow agents), finance workflows, and cross-functional processes through coordinated agent workflows. Within five months of its July 2025 rollout, 1C delivered a 50% improvement in operational efficiency, approximately 50% reduction in support ticket volumes, and 35% increase in employee engagement with 10,000 average daily users. The platform replaced fragmented, siloed AI tools and agents across the organization with a centralized, governed agentic ecosystem managed by the CIO function.
