ClimbX: AI-written X content in your own voice, $1,276 MRR
ClimbX helps creators grow on X by analysing their last 100 posts to build a voice profile, then drafting on-brand posts, surfacing reply opportunities, and guiding a 60-day plan toward the first paid post. It reports $1,276 MRR from 44 subscriptions, verified through Stripe on TrustMRR. The differentiator is voice fidelity rather than generic writing, though the X-growth niche is crowded.
