About Sierra

What the tool does and who it's for

Sierra is an enterprise-grade conversational AI platform designed to transform customer service through autonomous agents. Co-founded by Bret Taylor (OpenAI Chair and former Salesforce co-CEO), the platform uses a proprietary 'Constellation' multi-model architecture that orchestrates LLMs from OpenAI, Anthropic, and Meta to ensure accuracy and minimize hallucinations. Unlike basic chatbots, Sierra agents are action-oriented, connecting directly to backend systems like CRMs, order management, and data warehouses to perform complex tasks such as processing refunds, managing subscriptions, and updating records. Following the 2026 acquisitions of Receptive AI and Fragment, Sierra provides a unified experience across voice, chat, email, and SMS, serving high-scale industries including finance, healthcare, and retail.

Key capabilities

Constellation Architecture: Orchestrates multiple LLMs to cross-verify facts and prevent hallucinations.
Agent Studio: A no-code visual interface for CX teams to manage brand guidelines and conversational flows.
Agent SDK: A developer toolkit for building complex, programmatic skills and multi-agent orchestration.
Action-Oriented Agents: Capable of executing real-world tasks like updating CRMs and managing orders via secure APIs.
Ghostwriter: An AI tool that converts SOPs and whiteboard photos into production-ready agents in minutes.
Unified Omnichannel: A single agent logic deployed across voice (IVR), web chat, SMS, and WhatsApp.
Live Assist: Real-time guidance and auto-drafted responses for human agents during escalations.
Deterministic Guardrails: Combines generative creativity with hard business logic for high-stakes compliance.
