The challenge

A first-time founder with a publisher catalogue and no technical team. The product had to work on low-bandwidth connections across the region, handle offline listening, and scale as the library grew.

The outcome

Six years after launch, Bulbul Audio has crossed 100K monthly active listeners, ships on iOS and Android from a single Flutter codebase, and runs on a modest AWS footprint we continue to operate.

Highlights
  • Shared Flutter codebase on iOS, Android, and web
  • Offline-first listening with background downloads
  • Publisher ingestion pipeline that accepts ePub, MP3, and M4B
  • Cost per active user stayed under $0.15/month through two user-growth waves
