Building Frontier CX Agents | Interrupt 26

Description

In this keynote from Interrupt 2026, Cisco Customer Experience Fellow and Chief Architect Carlos Pereira pulls back the curtain on how one of the world's largest enterprise organizations is building and scaling frontier AI agents for its Customer Experience (CX) division. Carlos walks through Cisco's real-world journey from early chatbots and the "Agentic Foundation" to a fully AI-native "Renews Teammate" running in production across a $26B+ recurring revenue business. He shares candid lessons learned: why 95% accuracy wasn't enough for adoption, how bolting AI onto broken workflows can actually accelerate failure, and why the key to scaling agentic systems is keeping supervisors lean, introducing domain-specific planners, and building in self-correction by default. You'll come away with a practical architecture playbook—covering supervisor graphs, nested subgraph planners, deterministic task workflows, routing-first design, and long-term memory—plus an honest look at the organizational challenges of getting people to actually use these systems.
