Evaluation isn’t a gate.
It’s an engine.
Most teams are building blind—shipping agents with a demo and a prayer.
Coval is evaluation infrastructure for voice AI. Continuous improvement, not one-time testing.
Simulate
Synthetic conversations at scale to chart all the possible paths
Annotate
Conversations at scale to improve your evals in simulation & RL data
Trust Issues
Known Issues
Unknown Unknowns
Observe
Customer insights and unknown issue detection in real conversations
Simulate. Measure. Resolve. Repeat.
Thousands of realistic conversations with edge cases, compliance traps, angry customers. Run your metrics. See what breaks. Fix it. Run it again. Every cycle, the agent gets sharper.
Single pane of glass from sim to prod.
Coval gives you a single view for all your metrics from sim to production. Production-grade monitoring with the same lens you used in testing. So when something drifts, you see it immediately, and know exactly where to go to resolve.
Every failure makes the system smarter.
Some calls — in both sim and prod — need a human eye. Coval routes them to review queues. Your team annotates. Those annotations become test cases. Those test cases feed back into simulations. The loop closes and your data keeps compounding.
Three loops. One platform. Compounding excellence.

It's improving. Night and day compared to when we started the pilot.

I don't know how I did things before this. That was the 10x improvement.

You need an independent vendor to do evaluations. You can't have the people building the product also pretend that they can observe the product.
