What Sierra does
Sierra (sierra.ai) is an enterprise customer-experience (CX) platform for building and operating “AI agents” that can handle complex, multi-step customer journeys across channels (voice, chat, email, messaging, and ChatGPT). Rather than deploying single-use support bots, Sierra positions its agents as relationship-driving systems that can pursue longer-horizon goals (spanning days or months) and execute actions by connecting to enterprise systems of record. The company highlights an “outcomes-based” approach to pricing, aiming to align cost with the value delivered by the agent. Sierra’s platform includes tooling for agent building (Agent Studio), agent runtime/orchestration (Agent OS / “Horizon”), knowledge grounding and context management (Context Engine and related capabilities), continuous evaluation and optimization (Insights and Explorer), and multimodal channel support (including Voice Personas and multimodal conversation experiences).
