Five9's positioning of human-in-the-loop AI represents a deliberate recalibration of how contact center leaders should think about automation maturity. Rather than treating human intervention as a failure state, Jonathan Rosenberg argues that mature AI strategies must embed humans as active participants in continuous learning, governance, high-risk decisions, and emotionally complex interactions. This reframes the automation conversation away from the false binary of "AI or human" toward a more nuanced model where the two operate in complementary roles. The practical implication is significant: teams chasing 100 percent automation are optimising for the wrong metric. Instead, CX leaders should focus on where AI creates genuine value—handling high-confidence, repeatable tasks—whilst preserving human judgment for interactions where customer lifetime value, regulatory risk, or emotional stakes demand it. This approach requires stronger auditing, monitoring, and performance evaluation infrastructure than most organisations currently maintain, particularly as agentic AI systems become more autonomous.
The staged implementation pathway Five9 advocates—starting with simple, high-confidence use cases, proving value, building oversight structures, then expanding—directly challenges the aggressive rollout timelines many vendors promote. For teams already deep into Zendesk or Salesforce deployments, this suggests a need to audit current automation scope and ask whether you've optimised for speed of deployment rather than quality of outcomes. The governance gap is real: most contact center platforms excel at agent performance metrics but lack the sophisticated monitoring frameworks needed to evaluate AI agent behaviour at scale, particularly around edge cases and customer sentiment. Organisations that invest in this oversight infrastructure now—rather than treating it as a post-implementation concern—will have a competitive advantage as regulatory scrutiny around AI decision-making intensifies. The question for CX leaders is whether your current vendor roadmap includes these governance capabilities, or whether you're building them separately through third-party tools.
In this CX Today interview, Nicole Willing speaks with Jonathan Rosenberg, Chief Technology Officer at Five9, about the role of human-in-the-loop design in AI-powered customer experience. Rosenberg explains why mature AI strategies should not treat human intervention as a failure or last resort. Ins
