What Sierra does
Sierra builds AI-powered customer experience agents that handle conversations across voice, chat, and digital channels for consumer-facing brands. The platform serves large consumer companies in retail, telecom, and financial services that need to deliver personalized, always-on customer support at scale. Sierra's agents are designed to go beyond scripted chatbots by understanding nuanced customer intent and taking actions like processing returns, updating accounts, and resolving billing issues autonomously. Founded by former Salesforce CEO Bret Taylor and former Google executive Clay Bavor, the company has rapidly scaled to a $10B valuation.
