Brooke Hopkins (@bnicholehopkins) is the founder and CEO of @covaldev, a simulation and observability platform that helps enterprises test, monitor, and evaluate AI-powered voice agents at scale.
Coval works with customers like Perplexity and Deepgram to process tens of millions of calls per month and has just raised a $28.2M Series A.
Brooke sat down with @harjtaggar to talk about how leading evaluation infrastructure at Waymo turned out to be surprisingly transferable to voice agents, why voice is emerging as the first productionized use case for autonomous agents, and how she narrowed a broad evals idea into a focused enterprise platform—including the moment a customer offered to pay her before she'd written a single line of code.
