Sierra
Conversational AI platform for building autonomous, action-oriented customer experience agents.
What is Sierra?
Sierra is an enterprise-grade conversational AI platform founded by Bret Taylor that enables companies to elevate their customer experience using autonomous AI agents. Unlike traditional chatbots, the Sierra startup platform builds highly sophisticated Sierra AI agents that don't just answer questions—they can reason, problem-solve, and take direct action within a company's infrastructure. By integrating seamlessly into your ecosystem, including Sierra CRM setups, order management tools, and support systems, it allows businesses to deliver empathetic, brand-aligned, and multilingual support 24/7 across both chat and voice channels.
