Attention is a market. We just made it liquid.

Kingpin is a live marketplace for attention: a vertical, infinite-scroll feed where founders pay to put their product in front of people, and the crowd decides in real time whether it deserves to stay there. A bid gets you in. Votes decide how long you last.

Because that’s a leaderboard, not a market — and leaderboards freeze. The first version of Kingpin worked exactly that way: highest bidder wins, decaying 5% a day. It was simple, and simple broke fast — whoever had the deepest pocket just sat at #1.

So position is now a hybrid: your bid sets a baseline, and the confidence-weighted crowd vote shifts it up or down from there. A card that the crowd hates bleeds rank even with money behind it — Sentiment_Steps ≤ −5 evicts it outright. A card the crowd loves can outrun a bigger bid. Refueling your position back up costs more every time you do it, so money alone can’t camp on top forever.

No black-box ranking model, no engagement-maximizing feed. The inputs are a public bid amount and a public vote count, and the formula that turns them into a rank lives in one file, unchanged for every card. What you see is what moved it there.

Kingpin is built and run independently by Suraj Mishra — one person, no team, no funding round. Follow the build on X at @Surajm_.
