Flo's 2 tactics

Flo · B2C · period tracking app

Pitch the app as #1 in women's health instead of competing in all of health
Became the first women's health unicorn: $200M+ raised at a $1B+ valuation

Rather than competing as a general health app, narrowed its category to women's health / menstrual cycle tracking so it could confidently claim to be #1 in that niche. Paired with strong metrics, funnels and testing.

Run over 100 experiments a month
Guest cites it as part of what made it a top health app; no direct numbers

Flo's team ran over 100 experiments a month. Guest advises small apps to start testing pricing, paywall UI/UX, color schemes and fonts early and often, pushing experiment count up.
