Senior Product Manager, Growth

SuppCo, acquired by Function Health, helps people understand supplements and connect what they take to measurable outcomes through personalized guidance, product quality ratings, and routine analysis. The Senior Product Manager, Growth will own the full growth engine across acquisition, onboarding, activation, monetization, and retention, with a major focus on scaling a new membership experience. The role will lead experimentation, AI-powered product development, cross-product growth between SuppCo and Function Health, and data-driven product strategy.

Responsibilities:

• Own 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

Requirements:

• 5+ 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
• 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
• We are a remote-first organization that meets quarterly for team onsites in person
• our onsites are mostly held in NYC, though occasional travel may be expected
• Experience 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)
• New York Tri-State area candidates are preferred but not required
• Experience with LLM-based products, chatbots, or agentic systems is a plus
