Klariqo

Klariqo is the compliance layer for call centers, BPOs, and pay-per-call agencies.

In regulated outbound (SSDI, ACA, Medicare, Debt Relief), every call becomes audit-ready evidence instead of a 2% QA sample and a 98% blind spot. Klariqo also runs AI voice agents that register directly on VICIdial or any SIP dialer as a remote extension. No Twilio, no dev team, 10-minute setup. 100,000+ calls in production across regulated verticals.
