Sierra — Technical Overview
Sierra is an enterprise-grade conversational AI platform headquartered in the United States, designed to power customer-facing AI agents at scale. Key architectural and developer-relevant highlights include:
- Multichannel deployment across chat, SMS, WhatsApp, email, voice, and ChatGPT — enabling a single agent logic layer to serve multiple surfaces.
- Ghostwriter — a no-code/low-engineering AI agent builder that allows teams to configure and deploy agents without requiring dedicated engineering support.
- Horizon — a long-horizon planning and proactive engagement engine that enables agents to reason across multi-turn, extended interactions and initiate outreach.
- Insights Explorer — a multivariate conversation experimentation and observability toolset for analyzing agent performance, running A/B-style conversation experiments, and monitoring outcomes at scale.
- Outcome-based pricing model — billing is tied to delivered value rather than seat counts or API call volume, aligning platform costs with measurable business results.
