About Prosper AI:
At Prosper AI, we're pioneering the most advanced conversational AI agents tailored for the healthcare industry. Since our founding, we've successfully onboarded dozens of major customers, empowering hospitals and multispecialty clinics to get paid faster and more efficiently, through streamlined revenue cycle management.

Our AI agent, Paige, handles tasks like eligibility checks, prior authorizations, claim status follow-ups, and patient scheduling, reducing costs by over 50% for medical billing teams.

The Role:
We're hiring a Founding Growth Marketing Manager to define and scale our go-to-market messaging, brand presence, and growth narrative.

• Translate product capabilities into crisp, credible positioning and messaging
