Founding Growth Marketing Manager

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. We’re backed by top investors including Y Combinator (Airbnb, Coinbase) and Emergence Capital (Salesforce, Zoom), trusted by innovative healthcare organizations, and are reshaping a $4T industry.

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

You’ll work cross-functionally with the founders, sales, product, and design to create a magnetic and repeatable marketing engine. This is a high-impact, high-visibility leadership role with room to grow into a VP-level position.
The role is 100% in person in New York City.

• Drive a LinkedIn and content strategy targeting healthcare billing leaders

• Develop our brand voice, including copy, tone, color palette, and design themes

• Shape and execute a conference strategy—from booth design to talk tracks

• Lead PR efforts targeting our ICP: providers, billing companies, and payors

• Translate product capabilities into crisp, credible positioning and messaging

What We’re Looking For

• 3–6+ years in B2B product marketing, ideally in AI, SaaS, or healthcare

• You’ve led marketing for a technical product and created GTM assets from scratch

• Strong writing, storytelling, and brand-building instincts

• Portfolio of work that includes websites, case studies, content, and campaigns

• Experience collaborating closely with product and sales teams

• Self-starter who thrives in early-stage environments with high autonomy

Bonus Points

• Experience marketing to healthcare RCM, IT, or provider stakeholders

• Background in design, copywriting, or creative direction

• Own the brand and voice of a startup transforming healthcare

• Competitive base + equity — we hire like owners and pay like it

• Work closely with top engineers, operators, and early-stage leaders

• In-person NYC team with fast feedback loops and high trust
