Sierra Co-Founder Says AI Agents Can Resolve Up to 80% of Customer Inquiries

Sierra co-founder Clay Bavor discussed the state of enterprise artificial intelligence adoption in an interview on CNBC International’s The Tech Download, on July 14, 2026.

AI agents capable of fully resolving 50% to 80% of incoming customer inquiries without human involvement can deliver a significant return for enterprises, Bavor said. Sierra builds customer-facing AI agents for functions including customer service, sales, and mortgage origination.

Enterprises are increasingly deploying fully autonomous agents rather than tools that simply assist human staff, Bavor noted. The difference in return on investment between an agent that fully resolves a case and one that makes a human employee "10 or 15 or 20% more productive" is significant, he added, both financially and for the customer experience.

Guardrails, Value and Execution

Sierra layers supervisory agents on top of its customer-facing agents to monitor output in real time, Bavor told CNBC. These supervisory agents can flag responses that fall outside approved boundaries, such as dispensing financial or medical advice, and either route the case back to the primary agent or escalate it to a human employee.
