Is Deepgram trustworthy?

Deepgram publishes named customer case studies on its own site with specific figures and, in some cases, attributable quotes. Documented outcomes traced to those public pages include 2-4x more accurate alphanumeric transcription (Five9), greater-than-90% transcription accuracy (CallTrackingMetrics), and a 93% compliance-risk reduction with a 27% operational-efficiency lift (Creditas). These are the companies' own published claims, sourced and dated rather than independently audited.
