Redefining Customer Experience with Agent Operating Procedures (AOPs)
In a crowded landscape of customer support tools, Decagon stands out by prioritizing product innovation. Its proprietary Agent Operating Procedures (AOPs) framework allows customer experience teams to shape and evolve AI agent behavior in real-time using natural language instructions. Meanwhile, technical teams maintain complete access to and control over the agent’s underlying code.
This dual-layered approach enables businesses to implement, iterate, and scale conversational AI rapidly—often going live within weeks without the need for expensive professional services or long development cycles.
Decagon also provides full visibility into agent performance across channels, empowering teams to track impact, troubleshoot issues, run safe experiments, and fine-tune user interactions at scale.
