The Brief

What Sierra does

Sierra is a conversational AI platform that businesses use to build and run customer service agents. One agent can work across chat, SMS, WhatsApp, email, voice and ChatGPT. Teams build agents in Agent Studio, or let Ghostwriter create one from uploaded procedures and transcripts or from a plain-English goal. Horizon handles longer-term planning, customer context and proactive engagement, and Insights adds Explorer, Monitors, Experiments and Observability for watching how agents perform. Sierra lists SOC 2, ISO 27001, ISO 42001, HIPAA, GDPR, FedRAMP and PCI DSS among its trust commitments. Pricing is outcome based: customers pay for the results the agents deliver, and exact figures are not published.
