Sierra launches Ghostwriter, a self-service AI agent builder powered by natural language prompts

Sierra, an AI customer experience platform led by ex-Salesforce CEO Bret Taylor and valued at $10B after its last funding round in November, has unveiled Ghostwriter, a product that builds AI agents for tasks like customer service based on natural language prompts, removing the need for the forward-deployed engineers Sierra has relied on to onboard customers. The self-service approach could significantly lower Sierra's operational costs while making its platform more accessible to enterprises looking to deploy agents across sales and supply chain functions. The launch comes as large companies move from testing agentic AI to actively incorporating it into core business workflows, according to The Information.
