Work with us

Safe voice agents for the physical world.

Wearables, care devices, vehicles. Prologue tests every change against audio and realistic conditions before it ships in your hardware.

Voice agents guide and support us.

So when they fail, it breaks our trust.

Prologue saves those relationships
before they break.

Test your agent on both technical & emotional skills

Latency, tool-call accuracy and time to first response, measured in the same run as personality, patience and how it handles an emergency.

Fully integrated web & mobile testing

Drive the real product: iOS and Android UIs alongside web, so the agent is tested through the surface your customers actually reach it on.

Bespoke CI/CD tests for all situations

Every persona and edge case gets a suite of its own, wired into your pipeline so it runs on each deploy, next to prompt and code review.
