About the role

Making preventive health the default for every human in Europe

Location: Paris (hybrid) | Reports to: Philippine, Head of Marketing

Lucis is building the new standard of preventive health. Clinical-grade blood diagnostics. Personalized health protocols. Backed by General Catalyst. ~€2M ARR and growing fast across Europe.

We're looking for a Lifecycle / CRM Lead to own everything after the first registration.

What you'll own:

  • Activation flows from registration to customer
  • Customer onboarding from purchase to first blood result
  • Email and SMS strategy, execution, and copy
  • Customer segmentation and behavioural personalisation
  • Subscription and repeat purchase optimisation
  • Referral program (currently underperforming — you fix it)
  • Retention metrics, cohort analysis, NPS

What good looks like:

  • 30-day onboarding sequence with 70%+ completion
  • Referral rate from <3% → 8%+ within 6 months
  • 90-day churn reduced by 15% vs. baseline
  • You know the LTV impact of every lifecycle program you run

What we're looking for:

  • You've owned lifecycle/CRM — not contributed to it, but built it and measured the results
  • You can show retention or LTV improvement with actual numbers
  • You're proficient with modern email/SMS platforms (Klaviyo, Braze, Customer.io)
  • You can write — this role includes writing emails, not just designing flows
  • You understand cohort analysis, segmentation, and incrementality measurement
  • You're French or English native or near-native, with professional English/French

Nice to have:

  • Subscription or membership business experience
  • Has built a referral program from scratch
  • Background in health, wellness, or DTC
  • Multi-market lifecycle experience

Why Lucis:

  • You establish the baseline — there's no predecessor and no ceiling
  • Improving retention by 10% = same impact as acquiring 10% more customers at zero CAC
  • Greenfield: you choose the tech stack, build the segments, own the roadmap
