What is Sierra?
Sierra is an AI calls tool that builds customer-facing AI agents that resolve real support tasks. Sierra builds AI agents that run customer support across voice, chat, email and WhatsApp in 59 languages. Agents connect to CRM and order systems to finish tasks, while Ghostwriter and Explorer cover agent authoring and conversational analytics.
Sierra is a platform for building and running AI agents that handle customer conversations directly. Agents are created once and deployed across voice, chat, email and WhatsApp, running continuously in 59 languages. The stated goal is to resolve the tension between better customer experience and higher service cost: reach more people, more often, with more personal treatment, without proportionally growing a human team. The agents are designed for human-level reasoning and natural language, so they can read context and react to signs of frustration while staying on brand. Beyond answering questions, they connect securely to systems of record such as order management and CRM, which lets them carry a task to completion. The examples given are processing an insurance claim, returning an order and originating a mortgage. That depth pushes Sierra well past FAQ bots and into workflow automation for real service operations. Two companion products support the build and the follow-up. Ghostwriter lets a team describe the behavior they want and have the agent's prompt workflows, integrations, guardrails, tone and style generated or modified. Explorer answers natural language questions using analytics and sampled customer conversations, returning findings and recommendations rather than raw dashboards. Testing, automated monitoring and proactive insights are built in so teams can see why an agent made a decision and where it can improve. Sierra positions itself as a partner rather than a self-serve tool. An expert agent development team with hundreds of deployments works alongside customers, and delivery is measured in weeks with agents that expand in scope over time. The company reports that 40% of the Fortune 50 use the platform, with deployments in financial services, telecom, tech, healthcare, travel and retail. Pricing is outcome-based: customers pay when the software achieves specific, valuable outcomes, which suits enterprises that want spend tied to resolved work rather than seats or message volume.
