Introducing Voice Personas

What an agent does and how it expresses itself are two different things. Today, we’re launching Voice Personas so you can design both.

The next Horizon in agents

Horizon agents orchestrate outbound and inbound interactions over days or weeks — not just single conversations. A context engine and long-horizon planning turn every interaction into a compounding advantage, so your agents get smarter as your customer relationships deepen. It's Sierra's outcomes-based model at scale: you pay for results, not tokens.

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.

Year two in review

Sierra is heading into year three with over $150M in ARR, powered by rapid adoption from some of the world’s largest companies. The growth reflects a simple idea: when AI is built around real jobs to be done (not experiments), even the biggest enterprises can see meaningful impact fast.
