Share your Kindle library privately and let friends vote on what you read next (social voting + privacy)

Share your Kindle library privately and let friends vote on what you read next (social voting + privacy) targets a $6.0B = 200M active digital readers x $30 ARPU/year (community features + subscription + marketplace fees) total addressable market with medium saturation and a year-over-year growth rate of 8% annual growth in digital reading & social reading-tool engagement.

Key trends driving demand: social-reading -- readers increasingly use communities (Discord, Twitter, Instagram) to discover and discuss books, creating demand for social decision tools; exportable-data & sync tools -- services like Readwise and Goodreads exports make building cross-platform reading experiences far easier; AI-assisted curation -- LLMs and small models can summarize books and generate shortlists, making voting experiences simpler and faster; micro-communities & book clubs -- rise of small, active book clubs increases recurring engagement and monetization paths.
