Senior Product Manager-Growth

Alt is unlocking the value of alternative assets, starting with the $5 B trading-card market. They are seeking a Product Lead to own the growth engine, focusing on seller activation, buyer conversion, and building systems for experimentation and scaling.

Responsibilities:

• Own the end-to-end seller journey from first submission to high-frequency, high-value seller
• Identify and close drop-off points across onboarding, Snap to Sell, quote acceptance, vault intake, and resubmission
• Build product-led experiences that activate dormant sellers and increase submission frequency among our dealer segment — without requiring manual outreach
• Partner with Data and Lifecycle to deploy behavioral triggers and personalized experiences that drive submissions at scale
• Own search quality, card discovery, and browse experiences across the platform
• Drive search-to-bid conversion through better ranking, filtering, recommendations, and real-time Alt Value pricing context
• Surface the right cards to the right buyers at the right moment
• Define and run a disciplined experimentation roadmap across all buyer-facing discovery surfaces
• Own the experimentation framework across the platform — hypothesis definition, test design, metric selection, and decision rules
• Run high-velocity A/B tests across onboarding, activation, search, and submission flows
• Build a compounding library of experiment learnings the full product team can leverage
• Partner tightly with the data team on infrastructure to ensure fast, reliable experimentation
• Monitor and improve marketplace health — submission volume, listing rates, bid depth, and sell-through
• Identify supply and demand imbalances by card category, price tier, and seller segment and build product solutions to address them
• Use Alt Value pricing data as a growth lever — surfacing market signals to sellers and buyers that drive action
• Build and own the quarterly Growth roadmap tied directly to submission volume, buyer conversion, and time-to-liquidity
• Partner with Engineering, Design, Data, Lifecycle, and Ops to ship continuously
• Operate at both the tactical level (funnel details, experiment results, edge cases) and the strategic level (what bets we're making and why)
• Communicate tradeoffs and progress clearly to the CEO and leadership team

Requirements:

• 5-8+ years of Product Management experience with clear ownership of a growth surface, marketplace funnel, or PLG motion
• Demonstrated track record of driving measurable business outcomes through product experimentation and iteration
• Strong data fluency — Amplitude, Mixpanel, or similar, plus SQL or Python
• Experience partnering directly with Engineering and Data to build growth infrastructure, not just features
• Deep understanding of two-sided marketplace dynamics
• Scrappy, high-ownership operator who communicates with precision and moves without hand-holding
• Experience in collectibles, luxury goods, financial assets, or other high-value trust-sensitive marketplaces
• Familiarity with lifecycle tooling and how product and lifecycle intersect
• Experience with AI-assisted personalization, recommendation systems, or search ranking
• Background in operationally complex environments where physical and digital systems connect
