Paid

Testing, monitoring and benchmarking platform for voice and conversational AI agents, with simulations and production call observability.

Pre-Production Simulation: Runs thousands of synthetic conversations across personas and scenarios before go-live.
Production Monitoring: Tracks live calls for drift, latency, sentiment and failures in real time.
Self-Improving Loop: Flags issues, reproduces them in simulation, suggests prompt fixes and re-runs gating tests.
Adversarial Red-Teaming: Probes agents for jailbreaks, PII leaks and off-script or toxic behavior.
Cross-Platform Benchmarks: Runs identical scenarios across providers like Vapi, Retell and ElevenLabs and scores them.
Deploy Gating: Gates every release on a regression suite of scripted scenarios.
Compliance Controls: Offers signed BAA and DPA, HIPAA, SOC 2 and GDPR support, with VPC/SSO on enterprise.

Pre-Launch QA: Test an appointment-booking voice agent with synthetic patients before it goes live.
Vendor Bake-Off: Compare voice platforms head to head using the same scenarios and scoring.
Regression Gating: Block deploys that fail latency or hallucination thresholds.
Production Drift Detection: Alert on sentiment drops or dropped calls in live traffic.
Healthcare Compliance: Verify HIPAA disclosure, identity verification and recording notices are followed.
Stack Migration: Compare old and new voice stacks to confirm zero regression on key workflows.
