Sierra

Description

Sierra sells an Agent OS plus an Agent SDK that productises building a single agent and deploying it across many channels. The SDK composes skills (triage, respond, confirm) into multi-step workflows under explicit goals and guardrails, integrates customer knowledge, takes secure actions, and routes escalations to humans. Agent OS 2.0 (Nov 2025) added memory and an Agent Data Platform so agents can connect dots across time. Ghostwriter generates a production-ready multilingual multichannel agent with built-in guardrails. A blog series describes context engineering and LLM-as-judge monitoring as core operational tooling.

Solution

Agent SDK composes skills (triage/respond/confirm/...) into a workflow under explicit goals and guardrails. Per-customer context (history, real-time signals) feeds personalised responses; the agent can take secure actions and escalates to humans when needed. Agent OS 2.0 adds memory and an Agent Data Platform so the same agent persists context across conversations. Voice runs on a transcription platform supporting 70+ languages; quality is monitored with LLM-as-judge.
