Rank21
A fixed-supply AI leaderboard where early boosts go further
What is Rank21?
Rank21 is a transparent paid leaderboard for AI products and X profiles. Pick a target rank, set a boost, and preview the estimated placement before checkout. Completed boosts receive Rank Power (RP); more active RP ranks higher. Supply is capped at 21 million RP across 10 eras, and each new era gives half as much RP per dollar. No judges or hidden score—every position is clearly disclosed as sponsored.
