What is Sierra?
Co-founded by Bret Taylor, Sierra builds highly capable conversational AI agents for enterprise companies. These agents can take complex actions, access backend systems, and resolve customer issues autonomously.
Most customer support 'bots' are just decision trees that frustrate users. Sierra builds agents that can actually 'do' things by hooking deeply into a company's internal APIs.
