The company

A Paris-based venture founded by serial entrepreneurs with a proven track record. €5M in pre-seed funding raised to build a world-class team and launch a portfolio of high-retention wellness apps with one goal: becoming the #1 global app studio for Health & Fitness.

The model is creator-led: partnerships with trusted experts, influencers, trainers, athletes, and sports clubs who have real connection with their communities. They bring the audience - the company takes care of everything else: product, tech, growth, and monetisation.

First app already live on the App Store. Many more to follow.

The role

As Founding Growth Manager, you will own paid user acquisition for mobile apps end to end: channel strategy, creative strategy and production, and the data that drives both.

You will plan, launch, and scale campaigns across TikTok, Meta, and Google, build the creative testing engine behind them, and decide where every euro of budget goes. You'll shape retention and CRM alongside product, and use creator and influencer partnerships as creative and distribution levers. Dedicated creative manager and editor resources are yours to direct - your job is to set direction and scale what wins.

What you'll own

Mobile user acquisition - develop and execute growth campaigns across TikTok, Meta, Google, and other channels
Creative strategy - set the creative direction, angles, and testing roadmap; coordinate with creative managers and editors who handle production; scale what wins
Growth funnel - manage ASO, search ads, and conversion rate optimisation tests
Onboarding - treat the onboarding experience as a product: web funnel (ad click through signup, paywall, payment) and in-app onboarding; drive conversion with analytics and A/B testing
Retention and engagement - implement CRM strategies and automation to maximise LTV and reduce churn
Data - run your own analysis in attribution and analytics tools (AppsFlyer, Amplitude, ad platforms); own CAC, ROAS, and LTV reporting; use it to drive budget allocation and automate UA workflows
Cross-functional collaboration - work with product, engineering, creative, and partnerships teams; building a growth team becomes part of the role as we scale

Independently managed $1M+ in monthly ad spend

Entrepreneurial mindset - autonomous, creative problem solver, comfortable with fast-paced experimentation
Passion for sports, wellness, or community-driven growth is a plus
