Roark helps teams test, monitor, and improve their voice agents.
Voice AI is exploding, but reliability is still the #1 challenge. Teams spend hours manually testing agents and still miss failures. In the last 6 months, Roark has processed over 10M minutes of calls, powering monitoring and simulation for teams across the Voice AI ecosystem (including YC companies).
We close that gap by combining:
📊 Monitoring & Evaluation – 40+ built-in metrics (latency, instruction-follow, sentiment, etc.), custom dashboards, alerts, and the ability to define your own. Up to 15 speakers with automatic speaker identification.
🎭 Simulations & Personas – end-to-end phone/WebSocket simulations for inbound and outbound agents, with configurable personas (accents, languages, speech & behavior profiles). Define tests as conversations with a graph-based approach, so you can easily branch into edge cases and variants.
🔁 Full lifecycle loop – failed calls automatically become repeatable tests, so every failure makes your agent stronger.
Roark is the missing QA layer for Voice AI – helping teams ship agents they can trust.
