Y Combinator × Roark

Ship a voice agent that actually works.

Roark simulates real calls against your agent, scores every conversation, and catches regressions before your customers do. YC founders get credits to run it, on us.

$6,000

in credits for active YC batches. Roughly a year of our $500/mo plan, free. $2,000 for alumni.

Plus a direct Slack line to our founders and hands-on guidance on best practices for building reliable voice agents.

  • Simulate real calls at scale: scenarios, personas, 45 languages, and red-team runs
  • Load test with hundreds of concurrent callers, plus always-on health checks
  • Score every call on 64+ audio-native metrics, plus your own custom metrics
  • Monitor production: issue tracking, alerts, and OTEL tracing & dashboards
  • Gate every prompt and model change in CI/CD before it ships
  • Close the loop: an optimizer that drafts and verifies fixes from failing calls
