Sierra is a conversational AI company founded in 2023 by Bret Taylor, former co-CEO of Salesforce and chair of OpenAI's board, and Clay Bavor, a longtime Google executive. The company is headquartered in San Francisco and focuses on building enterprise AI agents for customer experience.
Sierra's platform enables companies to deploy branded AI agents across channels including chat, SMS, WhatsApp, email, voice, and ChatGPT. It includes Agent Studio for building and optimizing agents, an Agent Data Platform for personalization, and analytics for monitoring agent performance and outcomes.
The company has raised significant venture capital, reaching a multibillion-dollar valuation with investors including Sequoia Capital, Benchmark, ICONIQ, and Greenoaks, reflecting strong demand for enterprise agentic AI. Its growth is driven by adoption among large consumer brands.
Sierra differentiates itself with an outcome-based pricing model, charging primarily when agents successfully resolve customer issues rather than per seat or per interaction. This aligns vendor incentives with measurable business results and lowers adoption risk for enterprises.
Sierra serves large enterprises in financial services, telecommunications, retail, and subscription businesses, with customers including SiriusXM, SoFi, Brex, and Discord. It competes with established customer-service software vendors and a wave of new agentic AI startups in a rapidly growing market.
