We help teams building AI products find the failures their users don't report. You send us transcripts, we tell you your top 10 problems affecting user experience. So you can deploy with confidence, not anxiety.

Why AI is stuck

You can't read every conversation.

Manual review works at 5% scale — but you need to trust at 100%. What are you missing in the conversations you never see?

Traditional metrics miss what matters

CSAT, escalations, and resolution time only show what customers report. They miss the policy violations, brand mismatches, and confident-but-wrong answers that erode trust silently.

Stakeholders need answers you can't give

"How do we know customers aren't being misled?" When leadership asks, you need data—not survey samples or spot checks, but systematic quality monitoring across all conversations.
