RosterPoison

Why This is an Opportunity

Fantasy sports is a massive market dominated by ESPN and Yahoo, but the actual league management and social layer is terrible. A tool focused purely on the fun parts — trash talk, power rankings, trade drama — could carve out a loyal niche among the millions of commissioners who run leagues.

Key Pain Points

  • ESPN's fantasy app is functional but has zero personality and the league chat is basically unusable
  • As commissioner you spend hours manually tracking trades, vetoes, and rule disputes in a group chat
  • There's no good way to do power rankings with commentary without someone manually writing them up each week
  • Trade proposals happen in DMs and half the league doesn't even know about them until it's too late to counter-offer

Original Discovery

Fantasy sports leagues are chaos — trades happen on group chats, nobody remembers the draft order rules, and the commissioner gets blamed for everything. RosterPoison is a snarky, opinionated league management app where you can run drafts, post trade proposals with a public comment thread (for maximum trash talk), and auto-generate power rankings with roast-style commentary.
