Baby Mam, a pregnancy app offering community support & insurance products.

The app faced stalled growth despite a strong product–market fit. With downloads plateauing and a fixed budget, the challenge was clear: reignite momentum, double down on efficiency, and scale without simply spending more. Across the UK, Sweden, Spain, Italy, France, and Germany.

Monthly active users up +194% (from 9,710 → 28,601,
same budget)

Download → Registered conversion doubled (42% → 86%)

Customer Acquisition Cost reduced by 38%

+25% growth in the first month alone

App Store rating lifted from 4.1 → 4.6 iOS

To expand beyond traditional acquisition channels, we piloted TikTok to test cultural pull against performance benchmarks.

Partnering with four creators across Spain and the UK (120K+ combined following), we drove 221K+ views and 2,870 iOS downloads on a spend of just €905 achieving a CPI of €0.32.

Beyond installs, TikTok users showed +20% stronger activation rates than organic and +17% stronger than Meta/Apple Ads, proving TikTok’s power as both a cultural and performance channel.

Working with &Fine has been an absolute pleasure.
