Sierra Launches Ghostwriter: An AI Agent That Builds Customer Experience Agents — Bret Taylor Says 'Era of Clicking Buttons Is Over'

TechCrunch·medium signal

Sierra, co-founded by former Salesforce CEO Bret Taylor and valued at $10B, launched Ghostwriter — an agent that autonomously creates and deploys customer experience agents through natural language conversation. Users describe what they need, and Ghostwriter builds an agent that can chat, handle phone calls, speak dozens of languages, and take action on backend systems. Sierra deployed an agent for Nordstrom in four weeks using the tool. Taylor argues natural language will replace click-based enterprise software entirely.
