Coval raises $28M to stress-test AI voice agents

Coval, a San Francisco startup founded by a former Waymo engineer, has raised $28M in a Series A led by Norwest to test AI voice agents before they reach real customers. The company runs tens of millions of simulated calls to catch failures caused by accents, background noise, and off-script interactions. Customers reportedly cut manual QA work by up to 30x and deploy agents 10x faster. Over 60 organizations use the platform, including Zoom and Deepgram. Twilio Ventures also backed the round, signaling industry interest in independent evaluation tools. Coval competes with Hamming and Roark but claims to offer a full stack from pre-launch simulation to live monitoring.
