Coval raises $28M Series A to make voice AI deployment-ready →

Partners › AI Infrastructure

Complete your AI stack with evaluation.

Partner with Coval to bundle agent simulation, monitoring, and evaluation with your infrastructure, giving your customers the confidence to deploy.

The reliability layer on top of your stack.

Your infrastructure provides the foundation: telephony, models, compute, observability. Coval adds the reliability layer. Together, your customers get everything they need to deploy at scale.

Your customer's voice agent

Voice AI evaluation for every stage of the agent lifecycle.

Pre-launch simulation.
Test agents against thousands of voice scenarios before customers ship. Catch failures in barge-in, accents, latency, and audio quality.

Continuous monitoring.
Audio-native metrics on every live call. Flag drift, compliance issues, and quality degradation in real time.

Human review loop.
Capture failures, run A/B tests, and feed the results back into the simulation. A continuous loop that turns insight into expansion.

How the integration works.

Coval sits on top of what your customers already build. No new tools, no separate login.

Connect.

Customers point Coval at any agent built on your infrastructure: phone, websocket, or chat.

Evaluate.

Coval runs simulations before launch, monitors live calls in production, and flags issues for human review.

Observe.

Coval’s audio and semantic metrics feed back alongside your existing infrastructure data for one complete view.

The Coval difference.

Audio-first, not transcript-based.

Coval evaluates actual audio. Built for voice AI from the ground up. Catches failures text-only tools miss entirely.

Built by former Waymo engineers.

The same simulation-first principles that made autonomous vehicles safe, applied to enterprise voice agents.

Complete observability.

Your infrastructure metrics plus Coval’s audio and semantic metrics. Full visibility from transport layer to business outcome.

Open public benchmarks.

benchmarks.coval.ai continuously evaluates voice models in the open. Nobody else in voice AI evaluation does this.
