The Challenge

Probably Genetic is disrupting rare disease diagnosis and treatment access using AI and at-home testing, backed by Khosla and Y Combinator. You'll build a marketing function from the ground up that balances rigorous performance marketing with patient trust—the hardest problem in healthtech.

Your Mission

First 3 Months
1

Define and instrument the full patient acquisition funnel (discovery → diagnosis → trial/treatment enrollment) with clear CAC/LTV models across paid search, social, SEO, and partnership channels

2

Audit current brand positioning and competitive landscape; develop a 6-month brand and messaging narrative that resonates with patients, caregivers, and clinical partners

3

Map the existing marketing team structure, skills gaps, and hiring roadmap; secure budget and hire first 1-2 critical roles (e.g., performance marketer, content/brand lead)

4

Launch 2-3 high-impact experiments (channel testing, messaging variants, funnel optimization) to establish baseline performance and quick wins

By 6 Months
1

Build a fully instrumented analytics dashboard tracking CAC, LTV, payback period, retention, and channel ROI; present insights to board and leadership monthly

2

Execute 3-4 integrated campaigns connecting paid performance channels with brand storytelling, PR, and partnerships; measure impact on brand lift and patient outcomes

3

Grow patient acquisition volume by 30-50% while maintaining or improving CAC economics; optimize top 3 channels and pause underperformers

4

Establish a patient feedback loop (NPS, qualitative interviews, journey analytics) and translate 5+ insights into product and marketing improvements

KPIs You'll Own

Patient Acquisition Cost (CAC)

Track cost per new enrolled patient by channel (paid search, social, organic, partnerships); tie to payback period and LTV.

Lifetime Value (LTV) & Retention

Measure patient engagement, retention rate, and long-term value; ensure LTV:CAC ratio supports sustainable growth.

Conversion Funnel Metrics

Monitor conversion rates at each stage: discovery → diagnosis → trial/treatment enrollment; identify and optimize bottlenecks.

Channel Performance & Attribution

Measure ROI, volume, and quality by channel; use multi-touch attribution to inform budget allocation and testing.

Brand Health & Trust Metrics

Track brand awareness, consideration, and trust sentiment among patients, caregivers, and clinical partners; correlate with performance metrics.

Patient Experience & NPS

Monitor NPS, qualitative feedback, and journey satisfaction to ensure marketing messaging and experience align with patient needs.

Is This Role For You?

For You If
  • You've led B2C or B2B2C growth marketing in healthcare, biotech, or regulated industries and understand compliance, privacy, and patient trust
  • You obsess over metrics, experimentation, and data-driven decisions; you can code dashboards or at least read SQL and speak fluent analytics
  • You can do both: build rigorous performance marketing programs AND develop brand narratives that resonate with patients and clinical audiences
  • You thrive building teams and processes from scratch; you're comfortable being hands-on now and scaling leadership later
  • You genuinely care about patient outcomes, not just CAC curves; you'll push back if growth metrics conflict with patient needs
Won't Work If
  • You've only worked in non-regulated industries or don't understand compliance, privacy regs (HIPAA), or healthcare marketing nuance
  • You're purely a brand/creative marketer with little hands-on experience with performance channels, analytics, and experimentation
  • You need a fully built-out marketing team and infrastructure day one; this is a founder-mode role requiring scrappiness
  • You're uncomfortable with direct CEO reporting or being the single point of ownership for all marketing strategy
