Sierra is a conversational AI platform for enterprises, co-founded by Bret Taylor and Clay Bavor. It builds brand-specific AI agents that handle customer service across text and voice channels with empathy, deep procedural knowledge, and real-time actions like CRM updates and order management. Sierra stands out by using “supervisor agents” to reduce hallucinations and ensure trustworthy, policy-compliant responses. It powers voice-enabled interactions that scale human-like support 24/7.
