We’re seeking someone to own the relationship between our product and its users from the moment they hit a waitlist through their hundredth session. That means nurturing and retaining waitlists so we convert signups into activated users on day one. Then the focus turns to retention, re-engagement, and behavior nudges that increase session frequency, feature adoption, and lifetime value.

• Own the waitlist nurturing strategy — email sequences, engagement loops, referral mechanics

• Build segmentation models based on signup source, behavior signals, and engagement depth

• Design and execute the launch-day activation sequence to maximize waitlist-to-active conversion

• Instrument and track waitlist health metrics (open rates, click-throughs, referral rates, churn-from-list)

• Own retention and re-engagement across email, push, in-app messaging, and SMS

• Design lifecycle campaigns tied to key user milestones (first transaction, first week, reactivation windows)

• Build and optimize behavioral nudge systems — the right message at the right moment to drive the next action

• Partner with product to identify drop-off points and design interventions

• Run continuous A/B tests on messaging, timing, channels, and sequencing

• Report on cohort retention, LTV trends, and campaign-level performance

• Experience in lifecycle marketing, CRM, or growth marketing at a consumer app (fintech, gaming, or marketplace preferred)

• Hands‑on experience with marketing automation platforms (Braze, Iterable, Customer.io, or similar)

• Strong analytical chops — you think in cohorts, funnels, and retention curves, not just open rates

• Experience designing multi‑channel lifecycle programs from scratch, not just inheriting them

• Comfort with SQL or BI tools for self‑serve analysis

• Understanding of behavioral psychology as applied to product engagement

• Experience in crypto/web3 or with waitlist‑to‑launch conversion
