Founding Growth Product Manager (backed by Y Combinator, 1M+ ARR)

🧠 ABOUT LEGION HEALTH Legion Health is on a mission to deliver the best psychiatric care in the world—and to do it at scale. We're building the first AI-native mental healthcare company that uses generative AI to automate every possible operational and administrative task, freeing up clinicians to focus on what matters most: patient care. By combining deep clinical expertise with AI-powered operational infrastructure, we're creating a system that continuously learns from every interaction while radically improving access, speed, and outcomes. Today, we're turning weeks-long wait times into same-day appointments, crafting seamless digital experiences in a broken healthcare system, and scaling a company that patients genuinely trust. 🚀 THE OPPORTUNITY We're looking for a Founding Technical Growth Product Manager to lead the charge in building Legion Health's patient acquisition, onboarding, and retention engine. You'll design the full growth stack—strategy, systems, tools, and processes—to drive exponential patient growth and retention. From first-click attribution to long-term engagement loops, you'll transform our AI-powered psychiatric care platform into a scalable, high-conversion, high-retention consumer health experience. You'll collaborate directly with our founding team, growth lead, engineers, and clinicians. You'll also own the technical side of growth, including analytics implementation, source attribution, onboarding instrumentation, and growth experiment architecture. WHAT YOU'LL DO 🔁 Funnel Design, Instrumentation, & Optimization Design the entire patient journey funnel—from acquisition through onboarding, activation, and long-term engagement. Model and diagram the full user journey to identify friction points, drop-off stages, and time-to-value delays. Develop a structured tracking plan for every event in the onboarding funnel—specifying event purpose, event properties, and exact collection method. Collaborate with design and engineering to optimize layout, copy, and flow across mobile and desktop experiences. Replace fragmented tools and forms with a unified, event-instrumented onboarding experience. Integrate real-time eligibility checks into onboarding flow using API calls to payer databases. Enable behavioral re-engagement using event-triggered SMS/email communications (e.g. reminders to complete intake or schedule visit). Monitor funnel performance at every step to increase conversion and reduce drop-off. Ensure real-time data syncing into EMR and internal systems for downstream automation. 📊 End-to-End Analytics Stack Ownership Fully implement a modern analytics stack using: PostHog for product analytics and experimentation Google Analytics for acquisition insights Segment (or equivalent) for clean, centralized event collection Ensure all events are tracked client-side (clicks) and server-side (successes/outcomes). Use this stack to power dashboards, experiments, attribution, and lifecycle communications. 🧬 Source Attribution Build a source-of-truth attribution system for every patient: Attribute users by acquisition channel (e.g., Psychology Today, paid search, word-of-mouth, social, SEO). Integrate self-reported survey responses ("How did you hear about us?") to enrich tracking data. Use PostHog's full capabilities to backfill attribution when cookie/UTM data is missing. Ensure consistent UTM usage and campaign tagging across: All internal and external links (ads, emails, directory profiles) All landing pages and signup flows Create dashboards that tie attribution sources to downstream metrics like conversion to visit, CAC, and LTV. 📈 Centralized Growth Metrics & Reporting Integrate and visualize all core growth KPIs from Legion's internal sources (scorecards, ops dashboards, spreadsheets) into PostHog or equivalent. Metrics include: CAC (cost per retained user) Funnel conversion at every onboarding step Real-time provider availability metrics Time-to-intake and time-to-first-visit Weekly LTV and churn rates Build and maintain automated dashboards and alerting systems to enable fast decision-making and cross-team transparency. 🔬 A/B Testing & Experimentation Framework Implement tooling for A/B testing across key conversion points, including landing pages, onboarding screens, and communication flows. Design rigorous experiments with control/test logic, statistical significance thresholds, and clear success metrics. Test and optimize: CTAs Page layouts and messaging Eligibility flow structure Transactional and marketing emails Use experiment outcomes to guide product and growth roadmap. 🌐 SEO Optimization Own Legion's SEO roadmap and technical setup—from meta-tagging to AI-generated content and site performance. Design and run SEO A/B tests: Group similar pages (e.g., by diagnosis or region) into test/control cohorts Modify page-level elements (copy, CTA, H1 tags, structure) Attribute resulting traffic changes using PostHog or equivalent Ensure Legion content is AI-search optimized (e.g. ChatGPT Browse, Perplexity, Google SGE). Monitor and optimize SEO content ranking, CTR, and conversion metrics. 💬 Engineered Word-of-Mouth & Referral Systems Build viral loops into the product—referral links, post-visit share prompts, etc.—that drive unpaid organic growth. Create a native paid referral funnel, including attribution, fraud protection, and campaign management. Instrument and track: % of users exposed to referral options % who share invites Sign-up, visit, and retention rates of referred users Implement automated lifecycle communications (email/SMS) to increase referral funnel conversion.
