Artificial intelligence evaluation platform Coval has secured a $28 million Series A funding round to continue improving the deployment of autonomous voice agents across the enterprise.
Norwest led the funding round with participation from Base10 Partners, Twilio Ventures, and Y Combinator. Executives say the company has raised $31 million since its founding in 2024 and works with more than 60 organizations, including Zoom and Deepgram.
“Every company will deploy voice agents in the same way they have mobile and web apps, but today most companies don’t have the infrastructure to confidently deploy these systems,” Coval founder and CEO Brooke Hopkins said in a statement. “Coval allows teams to simulate, monitor, and continuously improve voice agents, allowing them to move from experimentation to reliable production at scale.”
Prior to founding Coval, Hopkins led Waymo’s Assessment Jobs Infrastructure team.
“Voice will become the most important interface for humans to interact with AI, and that change will create a whole new infrastructure layer for enterprises,” Norwest partner Scott Beechak said in a statement. “With extensive experience building self-driving technology rating systems at Waymo, Brooke is uniquely positioned to lead Coval in defining how companies can reliably deploy and scale voice agents. She helped prove the potential for self-driving cars to work and is now working on voice AI.”
According to the announcement, Coval works across the entire voice agent lifecycle, automating agent testing and continuously improving assessment accuracy, enabling organizations to perform assessments across millions of voice interactions.
Executives say the solution reduces manual quality assurance (QA) processes by up to 30x and increases voice agent deployment time by 10x.
The company plans to use the new funding to address reliability and compliance issues that organizations face during implementation, expand its sales and solutions engineering teams, and improve product capabilities. Coval points to the rapid growth of the voice recognition market, with an expected market value of $20 billion by 2031.
