Launched July 2025 and scaled to ~$59k MRR / 16.9k subscribers in about 13 months on a pure consumer motion: a TikTok-native topic (teen height anxiety), paid Meta/TikTok ads, ASO, and a hard onboarding paywall (~$3.50 blended ARPU). No founder audience at all — 0 X followers, identity undisclosed — the exact inverse of the founder-led model. Success spawned brand-squatting clones on both stores; by Aug 2026 the founders listed the business for sale at $1M (~1.5x annual revenue) while MRR was still growing.
"GoTall - Height Predictor" (Grow Labs LLC) converts in-store: 6.8K ratings at 4.6 average, ranked #118 in Health & Fitness at capture, free download with $1.99–$59.99 subscription IAP behind an aggressive onboarding paywall.
The seller's own account of the growth mix: app store optimization plus social advertising across Facebook, Instagram, TikTok and Meta Ads. Seller-stated on the sale listing — no ad-library verification.
TikTok hosts a dedicated discover hub of user-generated GoTall content ("How to See Height Potential in Gotall") with #gotall videos reaching six-figure views, skewing teen/parent — organic demand running alongside the paid motion.
