SunSeek's 2 tactics

The Wellness Company · B2C · studio of health apps

Build several small apps for the same health crowd and promote each new one to existing users
Users overlap across apps; three apps reached ~$120K a year combined

Every app targets the same health and wellness audience (cold plunge and sauna tracking, morning light, posture, and next a health data aggregator). Many Go Polar users also use SunSeek and Posture AI. When a new app launches, it is marketed to existing users of the other apps, so there is no need to build a new audience or list, and the marketing isn't cold.

The Wellness Company · B2C · studio of health apps

Ship app after app in one studio, treating each launch as practice for the next
Second app was better built on day one than the first; no numbers

Set up The Wellness Company as a product studio because he didn't know which app would win. Launched Go Polar, then SunSeek, then Posture AI, treating each app as another repetition of building product. SunSeek was crafted better than Go Polar on day one because of the reps.
