Movie & Show Ranking App (Social Taste Profile)

An app that lets users rank movies and TV shows to build a taste profile, then discover recommendations from friends or similar users. Target: entertainment fans who want a fun way to track and share their viewing habits.

Letterboxd's explosive growth post-pandemic — it crossed 10 million members in 2023 — validated that people genuinely want a social layer around film taste, not just a watchlist. The problem is Letterboxd is the incumbent here, and it's entrenched; building a competitor requires either a meaningfully differentiated angle (TV-first, short-form video, hyper-social ranking mechanics) or a distinct demographic wedge, neither of which is guaranteed to work. The $1k–5k/mo revenue band is realistic only through ads or a thin premium tier, since users in this category have low willingness to pay and churn fast if friends don't also adopt — network effects cut both ways. The most likely failure mode is the cold-start problem: a taste graph is worthless without a critical mass of friends on the same platform, and most solo founders can't manufacture that.
