About Sierra
Sierra.ai is a conversational AI company founded in 2023 by Bret Taylor and Clay Bavor, notable Silicon Valley leaders with extensive experience at Salesforce, Google, and Facebook. The company focuses on democratizing advanced AI to help businesses of all sizes enhance customer interactions. It officially launched publicly in February 2024.
The platform comprises two main components: AgentOS, which serves as the core operating system to build, deploy, and manage AI agents integrated with company systems and compliance protocols, and Experience Manager, which offers tools to design branded conversational experiences and monitor AI performance in real-time. Sierra’s AI agents are trained on company-specific data and supervised by additional AI layers to ensure accuracy, compliance, and alignment with brand voice and policies.
Sierra’s AI agents do much more than answer queries; they can perform actions such as updating CRM entries and managing orders, providing a holistic and scalable approach to customer service. Their omnichannel deployment supports chat, voice, and more, making the solution adaptable to enterprise infrastructure.
Since its founding, Sierra has secured major clients like WeightWatchers, Sonos, SiriusXM, and OluKai, and achieved significant financial milestones, including raising $285 million in funding and reaching a valuation of $4.5 billion by late 2024. The company prides itself on augmenting human customer support teams by handling routine interactions, allowing human agents to focus on complex cases.
Headquartered across multiple offices including New York, Atlanta, London, and San Francisco, Sierra continues to push the boundaries of applied AI, delivering measurable business impact and transforming customer experiences at scale.
