Coval Raises $28M Series A Led by Norwest to Build Simulation and Monitoring Platform for AI Voice and Chat Agents — 30× QA Reduction Claimed, Zoom and Deepgram Among Early Customers

Coval raised $28M in Series A funding led by Norwest, with participation from Base10 Partners, Twilio Ventures, and Y Combinator, to scale its testing and monitoring platform for AI voice and chat agents. The company lets enterprises simulate thousands of agent conversations and track live performance before and after deployment, with customers reporting up to 30× reduction in manual QA work and 10× faster deployment time — currently serving over 60 organizations including Zoom and Deepgram. The raise comes as enterprises pushing voice agents to production face an acute need for pre-deployment validation infrastructure that doesn't yet have an established market leader.
