Full-time

Supp Co is on a mission to help people make sense of supplements and connect what they take to measurable outcomes in their bodies. Our platform helps users find high-quality products, optimize their stack, and understand what's actually working—powered by our proprietary Trust Score quality rating system, our Stack Score routine analysis algorithm, and SuppIQ, our AI companion for personalized guidance.

Earlier this year, Supp Co was acquired by Function Health, the membership platform that gives people a complete picture of their health through lab biomarker testing and clinician-backed insights. It's a natural fit:
Function shows you what's happening inside your body, and Supp Co helps you act on it with confidence. The full Supp Co team has joined Function for the long haul, and together we're building the most trusted health optimization experience anywhere—for millions of members.

This is a rare moment, as Supp Co and Function are launching a category-defining feature in late 2026 that will change how users use supplements forever. You'd be joining an experienced founder-led team with a track record of building and scaling category-defining products, now backed by Function's reach, data, and membership base. The ambition is big, the runway is real, and the work matters.

Supp Co is seeking a growth-focused Senior Product Manager to join as our first product hire beyond the Head of Product. You'll own growth across all of Supp Co — acquisition, onboarding, activation, monetization, and retention across the entire experience. The single biggest component of that mandate is a new (currently confidential) membership initiative: turning our large and growing user base into active, repeat purchasers.

Reporting directly to our Head of Product, you're a growth specialist with marketplace, subscription or B2B2C experience who can rigorously test at speed and scale.

You'll own Supp Co's growth funnels end to end, including into and through our new membership experience, from acquisition and onboarding to activation, first purchase, and repeat purchase, while building and running an ambitious experimentation roadmap across all of them.

Additionally, you'll work with the Head of Product to create a coherent, high-performing experience across Function Health and Supp Co, building funnels between the two apps that convert and scale.

This is a unique opportunity to own the growth engine at a company with exceptional traction and a defensible data moat, at a genuine inflection point.

• Own growth end to end: Own Supp Co's full growth engine across the entire experience — acquisition, onboarding, activation, monetization, and retention on both mobile and web. Define the growth strategy, find the highest-leverage opportunities wherever they are, and drive the metrics that matter.
• Scale the new Membership experience: Own the funnel into and through our new membership experience — from awareness and onboarding to first purchase and repeat engagement. Drive transactors, purchase frequency, and revenue per user. Partner closely with the Head of Product and business team.
• Growth loops & cross-sell: Design and optimize activation and upsell loops across our products and partnerships — including between the Supp Co and Function Health apps — turning engaged users into repeat purchasers and building growth mechanics that compound over time.
• Experimentation & optimization: Design and run rigorous A/B tests across key stages of the funnel, from onboarding through purchase and retention. Continue a culture of experimentation and rapid iteration, and establish or improve the practices that let a fast-moving, AI-accelerated team ship and learn quickly without losing rigor.
• Activation & onboarding: Own the new-user experience so that more users reach the "aha" of a trusted, personalized stack — and their first purchase — faster.
• Subscription & membership monetization: Help evolve and optimize our Pro membership — conversion, value communication, retention, and lifetime value — as its role in the…
