Sierra

Sierra is a platform that enables businesses to create and deploy AI-powered customer experience agents.

Sierra provides tools for building rich interactions like dynamic forms, calendar pickers, order-tracking widgets, and payment flows directly within the chat interface. Behind the scenes, Sierra uses large language models combined with a proprietary reasoning layer that ensures accuracy and safety — the agent can check inventory databases, CRM records, and policy documents in real time, while also knowing when to escalate to a human agent. The system logs every conversation and allows businesses to analyze customer sentiment, drop-off points, and conversion rates.
