How Rest grows

Launched Rest by cross-promoting it inside Podcast App, whose audience overlaps; promotion was targeted at users listening at night. Added paid user acquisition funded by Podcast App's revenue, at a moderate budget: enough to get metrics and learn whether the product works, not to scale.

Podcast App saw many users listening at night to fall asleep. The team sized the market (~$30B/year US sleep spend across medication, mattresses and more) and interviewed people who had improved their sleep, learning they buy across many subcategories to solve the problem. Built Rest: the largest audio catalog for falling (back) asleep, plus an LLM-based personalized sleep coach for habits and routines.
