What is Sierra's outcome-based pricing model?

Sierra typically charges based on successful resolutions rather than per-seat or per-interaction. You pay when the AI agent successfully resolves a customer issue without requiring human intervention.

Does Sierra offer a free trial?

No, Sierra is an enterprise-focused solution and does not currently offer a public free trial or self-serve signup.

Can I build agents without knowing how to code?

Yes, Sierra provides 'Agent Studio,' a no-code environment specifically designed for customer experience teams to build and manage agents using plain English.

Which platforms can Sierra agents be deployed on?

Sierra agents support a wide range of channels including phone (voice), web chat, SMS, email, and messaging applications like WhatsApp.

How does Sierra ensure the AI stays on-brand?

The platform allows you to define specific brand guidelines, personas, and guardrails that the 'Constellation' architecture enforces during every interaction.

What happens when the AI cannot resolve an issue?

Sierra performs a smooth handoff to human agents, providing them with a full context summary and suggested actions through its 'Live Assist' feature.

About Sierra Agent OS

What the tool does and who it's for

Sierra Agent OS is an enterprise-grade platform designed by Sierra (co-founded by Bret Taylor) to build and deploy sophisticated AI agents that do more than just answer questions—they take action. Utilizing a unique 'Constellation' multi-model architecture, it combines generative AI reasoning with deterministic business logic to handle complex customer journeys securely. The platform features Agent Studio for no-code workflow building and an Agent SDK for developers to define goals and guardrails programmatically. Sierra's agents integrate deeply with enterprise systems of record (CRM, OMS, CDP) to perform tasks like processing refunds, managing subscriptions, and troubleshooting technical issues across voice, chat, SMS, and email. Built for the Fortune 500, it emphasizes brand-aligned personas, empathetic communication, and rigorous governance to ensure every interaction remains trustworthy and accurate.
