Overview

Sierra is a conversational AI platform designed to help businesses transform their customer experience. Founded by former Salesforce co-CEO Bret Taylor and ex-Google executive Clay Bavor, Sierra builds AI agents that can handle customer interactions across chat, voice, and messaging channels with natural, empathetic conversations.

The platform stands out through its focus on enterprise-grade reliability and brand safety. Sierra's agents are built to stay on-topic, follow company policies, and escalate to human agents when needed. The system integrates with existing CRM and support tools, enabling actions like processing returns, updating subscriptions, and answering product questions.

Sierra is best suited for mid-to-large enterprises looking to scale customer support without sacrificing quality. Notable customers include WeightWatchers, SiriusXM, and Sonos.
