About
Sierra is a comprehensive AI customer experience platform built for the world's leading brands. It enables businesses to create highly personalized, human-feeling interactions at every customer touchpoint without sacrificing efficiency or scale. At its core, Sierra offers an Agent OS — a suite of tools to build, test, and continuously improve AI agents through multivariate experiments, real-time observability, and deep conversation analytics powered by ChatGPT-style research. Sierra's Agent Studio lets non-technical teams build powerful agents with guardrails, integrated knowledge bases, and third-party tool connections. For engineering teams, the Agent SDK provides declarative development workflows, CI/CD tooling, and multi-agent orchestration capabilities. The platform's Agent Data Platform personalizes every interaction using conversation history, CRM data, and real-time signals, enabling proactive outreach and intelligent recommendations. Sierra deploys a single unified agent across all major channels — chat, SMS, WhatsApp, email, voice, and ChatGPT — ensuring consistent, on-brand experiences everywhere. Notably, Sierra uses outcome-based pricing, meaning businesses only pay for proven value delivered. Trusted by leading brands across industries including home services, media, insurance, and retail, Sierra is purpose-built for enterprises looking to increase customer lifetime value while empowering every team to move quickly.
