Sierra

Sierra is a conversational AI platform used by major brands including Rocket Mortgage, Gap Inc., SoftBank, Uber, and Vanguard to build and deploy intelligent customer-facing agents across chat, SMS, WhatsApp, email, voice, and ChatGPT. Its Ghostwriter tool creates production-ready, multilingual agents from SOPs, transcripts, or plain-English descriptions, while Agent Studio provides a dashboard for building and managing agents. Insights uses AI-powered deep research to analyze agent performance, Horizon breaks complex customer outcomes into long-horizon planning steps, and Observability gives full visibility into agent actions, tool calls, and decision-making. Sierra is SOC 2, ISO 27001, HIPAA, and FedRAMP certified, and uses outcome-based pricing where customers pay for the value Sierra delivers rather than traditional per-interaction fees, available by contacting the company.
