Senior Product Manager, Growth

Senior Product Manager, Growth US - RemoteSuppCo 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 TrustScore quality rating system, our StackScore routine analysis algorithm, and SuppIQ, our AI companion for personalized guidance. Earlier this year, SuppCo 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 SuppCo helps you act on it with confidence. The full SuppCo 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 SuppCo 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.Role OverviewSuppCo 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 SuppCo — 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 SuppCo'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 SuppCo, 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.Key ResponsibilitiesOwn growth end to end: Own SuppCo'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 SuppCo 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 business evolves.AI product development: Drive strategy and execution for AI-powered growth surfaces, including SuppIQ (our supplement guidance chatbot), agentic buying experiences, and new AI-driven frontdoors that improve personalization, discovery, and guidance throughout the purchase journey.Data-driven decision making: Define KPIs and success metrics for growth initiatives, build dashboards to track performance, deeply analyze cohort and funnel behavior, and translate insights into high-impact product opportunities.User research & insights: Conduct qualitative and quantitative research to understand user motivation, purchase friction, and decision-making across the journey — using insights to inform growth hypotheses and strategy.Cross-functional leadership: Partner closely with Engineering, Design, Growth Marketing, and Operations to ship high-quality work rapidly while maintaining strong alignment on priorities and tradeoffs.Full product ownership: Beyond growth funnels, take end-to-end ownership of strategic initiatives across SuppCo's product as business priorities require.Qualifications5+ years of product management experience at consumer technology companies, with demonstrated expertise in growth.Growth track record required: Proven success driving measurable improvements in acquisition, activation, conversion, retention, or monetization through product-led growth and systematic experimentation.Marketplace, B2B2C or sharing economy experience: Experience building or optimizing marketplace, subscription, commerce, or transactional products — especially the demand and conversion side: purchase funnels, merchandising, cross-sell, and repeat-purchase mechanics.Strong analytical foundation: Deep proficiency with analytics tools (Mixpanel, Amplitude, SQL, etc.) and statistical methods to design experiments, analyze behavior, and measure impact.AI fluency: Comfortable building AI-powered features and using AI tools to accelerate your own work; you see AI as a capability to leverage, not a trend to chase. Experience with LLM-based products, chatbots, or agentic systems is a plus.Experimentation mindset: Fluent with A/B testing frameworks and statistical significance; you default to testing and measuring everything and can build scalable experimentation practices.Excellent product judgment: you identify the highest-leverage opportunities, prioritize ruthlessly by expected impact, and ship iteratively to learn fast.Versatile generalist who can tackle diverse product challenges beyond growth when the business needs it.Thrives in ambiguity: You make good decisions with incomplete information and stay effective through fast-moving organizational change.Strong communication and influence skills to build alignment and rally cross-functional teams around shared goals.Passion for health, wellness, and building products that genuinely improve people's lives.Nice to HavesExperience driving growth across both mobile app and web, with levers like ASO, SEO, push notifications, lifecycle/CRM, and web conversion optimization.Experience with subscription or membership business models.Background in health, wellness, nutrition, diagnostics, or the supplement industry.Experience with cross-sell, partner, or two-sided ecosystem growth (e.g., growing across two products or brands).Experience with personalization or recommendation systems.Experience with social features, community products, or content discovery.Previous experience in early-stage startups (seed to Series B).LocationWe are a remote-first organization that meets quarterly for team onsites in person.
