Founding Growth Intern Opportunity

We are a consumer health product currently in stealth and launching in fall 2026. We are building a new category at the intersection of regenerative medicine, longevity, and personalized health. Our goal is to give people a way to preserve their cells today for potential future medical applications, expanding their access to the possibilities of tomorrow's medicine. The company is backed by leading investors and being built alongside exceptional scientists, clinicians, operators, and consumer talent.

We are approaching a rare inflection point: our first customer experiences, initial clinic partnerships, and public launch.

We are looking for an exceptional Founding Growth Intern to work directly with our Head of Consumer Health and help bring an entirely new category to market. This is not a traditional internship. You will take meaningful ownership across growth, content, partnerships, customer acquisition, and launch strategy. You will work on real company priorities, contribute to live initiatives, and see your ideas move quickly from concept to execution.

One week, you might build a pipeline of high-value clinic or brand partners. The next, you might launch an outbound campaign, produce a short-form video, analyze our customer funnel, help execute an event, or develop a growth experiment designed to reach our first 100 founding members. We are looking for someone who wants proximity to the decisions, speed, ambiguity, and creative problem-solving involved in building a company from zero.

What

You'll Work On
  • Help build and continuously improve our go-to-market playbook
  • Develop hypotheses, launch growth experiments, measure performance, and recommend what we should do next
  • Track acquisition, conversion, engagement, and campaign performance
  • Identify under-explored channels and creative ways to introduce the company to new audiences
  • Test opportunities across referrals, partnerships, content, events, community, outbound, SEO, and paid acquisition
  • Focus on measurable outcomes rather than activity for activity's sake
  • Help develop content across platforms such as Linked In, Instagram, Tik Tok, X, Reddit, You Tube, and email
  • Create short-form videos, founder and expert content, industry explainers, product stories, testimonials, and launch materials
  • Monitor relevant conversations across longevity, consumer health, biotechnology, science, and culture
  • Find thoughtful ways for the company to participate in timely conversations and reach new communities
  • Build relationships with creators, experts, community leaders, and potential brand advocates
  • Translate complex scientific ideas into content that feels clear, compelling, and culturally relevant
  • Research target clinics, companies, creators, communities, and strategic partners
  • Identify key decision-makers and build high-quality prospect lists
  • Help craft personalized outreach across email, Linked In, introductions, and events
  • Support live partnership and business development conversations through research, preparation, and follow-up
  • Maintain an organized partnership pipeline and ensure opportunities continue moving forward
  • Help develop repeatable outreach strategies for different customer and partner segments
  • Help recruit and engage our first founding members
  • Support clinic activations, customer blood-draw experiences, gifting initiatives, and launch events
  • Assist with event planning, guest research, logistics, programming, and follow-up
  • Conduct customer interviews and turn insights into recommendations for messaging, product, and growth
  • Help create an exceptional experience across every early customer touchpoint
  • Conduct market, customer, and competitive research to inform positioning and go-to-market strategy
  • Create one-pagers, partnership materials, internal memos, presentations, and sales collateral
  • Help build and maintain our CRM, prospecting, reporting, and outreach infrastructure
  • Keep account records, contact information, activity tracking, and pipeline data accurate and actionable
  • Turn ambiguous questions into structured research and clear recommendations
  • Operate as a high-agency generalist, moving between strategy and execution based on the company's most important priorities
What Success Could Look Like

Within your first three months, you could:

  • Build a prioritized pipeline of high-value clinic, brand, creator, and community partners
  • Launch several measurable growth experiments from hypothesis through analysis
  • Help acquire and onboard our first founding members
  • Create content that meaningfully expands the company's reach and credibility
  • Develop a repeatable outbound or partnership playbook
  • Help execute an influencer, customer, clinic, or event activation
  • Surface insights that directly influence our launch strategy and positioning
  • Become a trusted and highly leveraged member of the founding consumer team
Who You Are
  • Exceptionally resourceful, proactive, and comfortable figuring things out without a detailed playbook
  • A strong writer and clear communicator with excellent…
