Sierra
Sierra is a conversational AI platform for enterprises to build customer agents across chat, voice, email and messaging, priced on outcomes.
About this tool
Sierra builds AI agents that large companies use to handle customer conversations and drive revenue, not only service. One agent can be deployed on voice, email, WhatsApp, SMS, chat and even ChatGPT. Its Ghostwriter tool creates a production-ready, multilingual agent from standard operating procedures, transcripts, whiteboard photos, audio recordings or a plain-English goal, with guardrails built in.
Once live, Sierra helps teams improve agents with automated updates based on flagged issues, deep research across conversations, proactive detection of conversations needing attention, multivariate testing and full traces of every tool call and knowledge lookup. Memory links conversations and systems for personalisation. Sierra charges on an outcome basis, so customers pay for the value delivered.
