Documented cause
Millie was a spoken word audio app targeting women, offering original fiction and non-fiction audio content. Founded by Kate Grover in San Francisco in 2018 and backed by approximately $3M, Millie aimed to compete with Audible but for short-form female-oriented stories. The startup could not achieve the content licensing costs needed to compete with Audible or Scribd, and user acquisition costs in the audio app space proved prohibitively expensive. The company shut down in 2020 without a public announcement.
Lesson
“Content-dependent audio apps need owned IP or exclusive deals; licensing alone creates unsustainable unit economics.”
