What they did
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.
