Coval, a startup building infrastructure to test, monitor, and improve enterprise voice AI agents, has raised $28 million in Series A funding led by Norwest, with participation from Base10 Partners, Twilio Ventures, Y Combinator, MaC Ventures, and Swift Ventures. The investment brings the company's total funding to $31 million and will support platform expansion and product development.
Improving Voice AI Reliability
Coval develops infrastructure that helps enterprises deploy voice AI agents with greater reliability. The platform provides simulation, testing, monitoring, and production analytics to identify failures before and after deployment. As voice AI adoption accelerates across customer service, scheduling, healthcare, and collections, Coval aims to solve the reliability challenges that emerge in real-world environments.
Supporting Enterprise Deployment
The company plans to expand its sales and solutions engineering teams while enhancing simulation capabilities across different accents, audio conditions, and complex conversation scenarios. Additional investments will strengthen integrations, monitoring, and human review tools that help enterprises continuously improve AI agent performance.
“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. … She helped prove self-driving cars could work, and now she’s tackling voice AI,” said Scott Beechuk, Partner at Norwest.
Scaling the Platform
Coval believes enterprise demand for reliable voice AI infrastructure will continue to grow as organizations move AI agents into production. The new funding will accelerate platform development and help more companies deploy voice AI systems with greater confidence.
