In this episode of In the Pit, we sit down with Laurent, co-founder of FocusTree — a productivity app for students — to break down how he leveraged short-form creator-led content to explode the app to 100,000 downloads in just 15 days.

Laurent shares the tactical, step-by-step breakdown of his viral growth playbook, from sourcing international creators to creating a gamified onboarding experience that hooks users. This is a masterclass in thinking media-first, product-second — and building sticky consumer apps in the TikTok era.

💡 Key Takeaways

• Media Before Product: Laurent validated FocusTree’s concept with fake mockups on Reddit and TikTok — only building after demand was clear.
• Creator-Led Growth: FocusTree works with 7+ international creators, paying ~$20/video with performance bonuses — resulting in ~12K daily downloads.
• Hyper-Optimized Onboarding: From SMS login to school-based friend sync, every screen is engineered for retention.
• Gamified UX: Users “grow a garden” by studying — a visual reward loop inspired by Strava and Duolingo.
• Decentralized Creator Ops: Coaches manage onboarding, feedback, and best practices across WhatsApp and School.com.
• Unlocking Virality: Winning TikTok formats last 2–3 weeks. Read comment sections for next-gen hooks.
• Underserved Niches: Look for outdated categories with passionate audiences (e.g., astrology, study apps) and remix the experience.
