Sierra

An AI platform designed to help businesses talk to their customers in a natural way. Sierra helps businesses build better, more human customer experiences with AI. Sierra is a conversational AI platform that helps businesses build and deploy autonomous AI agents focused on customer service and experience. These agents handle complex interactions across multiple channels and perform actions, not just chat. Sierra was co-founded in 2023 by Bret Taylor (former co-CEO of Salesforce, former CTO of Facebook, current OpenAI board chair) and Clay Bavor (former Google executive who led Google Labs and AR/VR efforts). Sierra targets large enterprises and leading brands that want to scale personalized, reliable customer support, especially companies already investing in complex customer experience operations. Agents deploy across chat, SMS, WhatsApp, email, voice, and even ChatGPT, unifying customer touchpoints into a single intelligent system. Sierra offers Agent Studio, which lets customer experience teams build, configure, and launch agents without writing code, although developers can use the Agent SDK for more advanced control. It uses Agent memory to remember conversation history, integrates with existing customer data systems, and applies configurable recommendation strategies to deliver tailored responses and proactive outreach.
