How Podcast App grows

Top-down: US broadcast radio ad revenue (~$10-13B) times the talk-radio share of listening (~25%), which is comparable to podcasts, gives billions a year locked in an untargeted legacy medium. Bottom-up (what YC cared about more, 'Netflix of podcasts'): how many subscribers are needed for a $100M/year business, which came to a few million. Repeated the exercise for the sleep market.

When launching the Android prototype on Google Play from inside Streema, a team member proposed 'The Podcast App', reasoning that something straightforward would help with search. The name stuck and became the company name.

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.

Over several years, to find the next leap in growth beyond core podcast playback, Podcast App ran experiments around education: creating its own content, thematic playlists by editors and curators, and a social podcast learning club like a book club run over WhatsApp.

After being rejected at the YC interview in late 2016 (froze under tough questioning about competing with Apple's podcast app), the founders raised a little from Streema's co-founders, put in their own money, and kept costs low. Reused Streema's acquisition, distribution and monetization skills to get traction fast. Reapplied a year later, prepared for a combative interview.

Podcast App originally earned mostly from ads, with a hidden subscription just for the few people who wanted to remove ads (billing via RevenueCat's SDK). The team then took the time to properly focus on subscriptions as the core business model.
