PRODUCT OVERVIEW

What is Sierra?

Sierra is a conversational AI platform that helps businesses build and deploy AI agents for customer experiences. Its Ghostwriter tool lets teams describe desired agent behavior in plain English or upload SOPs, transcripts, and recordings to generate production-ready, multilingual agents with built-in guardrails. Agents can operate across chat, SMS, WhatsApp, email, voice, and ChatGPT, connecting securely to systems of record to handle tasks like returns, claims, or mortgage origination. Horizon adds long-horizon planning and proactive engagement, while Explorer provides deep research and analytics on customer conversations. Sierra is aimed at enterprises in financial services, healthcare, telecom, retail, and other industries, and uses outcome-based pricing where customers pay for delivered results.
