Sierra, the enterprise AI startup led by Bret Taylor, introduced its Ghostwriter agent. An agent-as-a-service platform designed to autonomously build and deploy specialized AI agents from natural-language prompts, featuring a workflow that converts user descriptions into production-ready agents. The company also announced a $950 million funding round to accelerate expansion of its broader suite of customer-facing and operational AI agent offerings.
Ghostwriter creates deployable agents capable of handling tasks such as claims processing, returns and fundraising, and Sierra reported growing enterprise adoption across Fortune 50 customers alongside rapidly increasing annual recurring revenue. The platform is positioned to simplify the creation and deployment of agentic workflows without requiring extensive engineering resources.
For businesses, Ghostwriter promises faster implementation of task-specific AI systems while reducing operational complexity and time-to-value for automation initiatives. The launch reflects the broader shift toward platformized AI tools designed to embed autonomous agents directly into everyday enterprise workflows.
