Why Health & Fitness App Growth Is Harder Than It Looks

In this episode of Growth by Design, we sit down with Vasyl Sergiienko (ex-Meta, Google) to unpack why many classic growth playbooks break in health & fitness — and what actually works instead.

Motivation drop-offs, seasonality, creative messaging, web-to-app, and where AI genuinely helps — a deep dive into what makes this category structurally different.

What you'll learn

  • Why health & fitness growth behaves differently from other app categories

  • How motivation drop-offs and seasonality shape sustainable growth strategies

  • What really works in health & fitness creatives — and where teams oversell

  • How poor messaging hurts retention and monetization later

  • Lessons from the early web-to-app era, and when it still works today

  • Where AI truly helps in creative strategy (and will it replace creative producers?)

  • What growth teams are optimizing today that will look naive by 2026

  • How founders can design for sustainable growth from day one
