Artificial intelligence evaluation platform Coval secured a $28 million series A funding round to continue to improve the deployment of autonomous voice agents across enterprises.
Norwest led the funding round, with participation with Base10 Partners, Twilio Ventures and Y Combinator. The company has raised $31 million since its 2024 launch and works with over 60 organizations, including Zoom and Deepgram, executives say.
“Every company is going to have a voice agent just like they have a mobile app or a web app. But today, most enterprises don’t have the infrastructure to deploy these systems with confidence,” said Brooke Hopkins, Coval founder and CEO, in a statement. "Coval gives teams the ability to simulate, monitor and continuously improve voice agents, so they can move from experimentation to reliable production at scale.”
Prior to founding Coval, Hopkins led Waymo’s evaluation job infrastructure team.
“Voice is going to be the number one interface for how humans interact with AI, and that shift creates an entirely new infrastructure layer for enterprises," said Scott Beechuk, Norwest partner, in a statement. "With her deep experience building evaluation systems for autonomous technologies at Waymo, Brooke is uniquely positioned to lead Coval in defining how companies deploy and scale voice agents reliably. She helped prove self-driving cars could work, and now she’s tackling voice AI.”
Coval works across the voice agent lifecycle, automating agent testing to continuously improve evaluation accuracy and allows organizations to run evaluations across millions of voice interactions, according to the announcement.
Executives say the solution reduces manual quality assurance (QA) processes by up to 30x and increases voice agent deployment times by 10x.
The company plans to use the fresh funding to address reliability and compliance issues organizations face during deployment, expand its sales and solutions engineering teams and advance product capabilities. Coval points to the rapid growth of the voice recognition market, including an expected $20 billion value by 2031.
