Senior Director, Lifecycle Marketing

About this role

Seed Health is a microbiome science company pioneering clinically validated innovations for gut and whole-body health. Our portfolio of gut-directed products is developed in collaboration with leading scientists and backed by human clinical research. We’re best known for DS-01® Daily Synbiotic—the #1 digestive health probiotic in the U.S.—trusted by millions of people for its benefits in and beyond the gut, including skin, immune, and heart health.

We’ve since expanded our offerings to include PDS-08® for pediatric health, VS-01™ for vaginal health, and a new category of Co-Biotics for daily nutrition, energy, and sleep—each grounded in our commitment to scientific rigor, precision formulation, and impact across the body’s interconnected systems. Beyond the body, SeedLabs —our environmental research division—advances microbial solutions that restore biodiversity and support ecosystems affected by human activity.

We’ve built a profitable DTC business with category-leading retention, grown revenue 5x in the last 36 months, and expanded our reach across new channels and markets. With a robust clinical pipeline and continued expansion into new areas of microbiome health, we’re building for scale—with integrity, care, and curiosity.

Our work has been recognized by Fast Company (Most Innovative Companies, Brands That Matter, World Changing Ideas), TIME (Best Inventions), Forbes (America’s Best Startup Employers), and Inc. (Best in Business, Female Founder 100)—a reflection of the science behind our products and the stories we tell to bring them into the world.

We’re a galaxy-class team of researchers, clinicians, designers, engineers, storytellers, and builders—each aligned in our belief in the transformative potential of the microbiome. If you’re a kindred dot-connector looking to shape the future of health, join us.

Seed's owned channels are where the member relationship is built — from first touch to loyal subscriber and back again when needed. This role owns that entire arc. The Senior Director of Lifecycle Marketing is accountable for the full lifecycle: acquisition nurture, conversion, activation, engagement, retention, and winback, with end-to-end ownership of email, SMS, and any future explorations for other LCM mechanisms.

This isn't a campaign-calendar role, it’s a real business leader within out growth organization. Lifecycle at Seed is one of the highest-leverage growth engines we have — owned channels are our most efficient path to conversion, and a subscription business lives or dies on retention — and the person who thrives here treats conversion, churn curves, and reactivation rates as their scoreboard, not open rates. They're equally at home in data and in craft: rigorous about cohorts and incrementality, uncompromising about how the brand shows up in an inbox.

What You'll Do

Acquisition Lifecycle

• Own the acquisition lifecycle strategy — lead capture, prospect nurture, and conversion journeys that turn interest into first purchase

• Build and optimize the pre-purchase journey architecture: welcome series, education flows, browse and cart abandonment, and re-engagement of unconverted leads

• Partner with Performance Marketing and Growth on lead generation strategy, ensuring paid and owned channels work as one system — with lifecycle maximizing the value of every lead acquired

• Own conversion accountability for owned channels: how efficiently email, SMS, and push turn prospects into members

Lifecycle Strategy & Retention

• Own the end-to-end lifecycle strategy — onboarding, engagement, cross-sell, churn prevention, and winback — with clear accountability for retention, LTV, and reactivation outcomes

• Build a best-in-class winback program grounded in Seed's own data: who lapses, why, when they're recoverable, and what actually brings them back

• Design churn-prevention interventions triggered by behavioral signals, not just tenure

• Own cross-sell and expansion strategy across the portfolio — moving members from a single product to a deeper relationship with Seed

Channels & Orchestration

• Own strategy and execution across email, SMS, and push — journey architecture, cadence, targeting, and creative direction

• Drive channel expansion thoughtfully: grow reachable audience (SMS opt-in, app engagement) without degrading trust or deliverability

• Ensure every lifecycle touchpoint reflects the Seed brand at its highest expression — science-forward, premium, never spammy

Data, Segmentation & Experimentation

• Build and own the lifecycle experimentation program — holdouts, incrementality testing, and a clear read on what's actually working versus what's noise

• Translate behavioral segmentation into differentiated journeys and messaging, in partnership with Data and Product

• Develop the measurement framework for lifecycle across the full funnel: lead-to-member conversion, retention curves, cohort LTV, reactivation rate, and revenue per member — and report on it with rigor

Cross-Functional Leadership

• Serve as the primary lifecycle voice in commercial planning — launches, promotions, pricing changes, and subscription mechanics all run through lifecycle

• Partner closely with Digital Product on the on-site and in-app expression of lifecycle strategy (subscription management, upsell surfaces, personalization)

• Build a high-performing lifecycle team and operating cadence — with this role setting strategy and standards, not writing every subject line

Who You Are

• You have 8+ years in lifecycle, CRM, or retention marketing, with meaningful depth in subscription or DTC businesses at scale — and you've owned both acquisition and retention lifecycle, not just one side of the funnel

• You've built lifecycle programs from first principles — not just optimized an inherited journey map, but defined what the member relationship should be and built the systems to deliver it

• You're genuinely analytical — fluent in cohor
