Agent observability, evaluation, and continuous improvement for production AI
Capture spans, traces, and sessions across agents and LLM calls using OpenInference conventions built on OpenTelemetry, so instrumentation stays portable.
Run evaluations at span, trace, and session level to grade retrieval quality, tool use, and final answers across large production datasets.
An in-product agent that inspects traces, diagnoses likely root causes, and proposes fixes that engineers can review before shipping.
Self-host the leading open-source tracing and eval tool when you need to keep trace data inside your own infrastructure.
AI agents that work the revenue lifecycle alongside your sellers
Agents built on years of sales workflow data act across prospecting, deal execution, conversation intelligence, coaching, and forecasting.
Run multi-channel outreach so the right message reaches the right buyer at the right time, with context carried into the conversation.
Track deal progress, commitments, and risk in one place so sellers and managers know what has to happen next.
Capture what happened on calls and turn it into timely coaching and real-time guidance as objections come up.
