The idea
Nittro runs two always-open paid rankings: one for apps and one for creators on X. The first bid is $5. There is no hidden ranking model: settled totals set the order inside each board.
What is scarce
Each board has one #1 position. The highest settled total keeps it until another listing moves ahead. Every other listing remains visible at the rank its total earns.
Demand, honestly labeled
App listings can link a public Meta Ad Library count; creator listings show tracked profile clicks. These are discovery signals, not promises of demand, followers, signups, or sales. Outcomes are never guaranteed.
Built for the US market
Bids are in USD and Stripe handles payment. The launch is written for US founders, indie hackers, and internet businesses.
