Sankalp Sinha said Wednesday that TopFloor, a paid public leaderboard he launched on Aug. 27, crossed $1,100 in revenue on Monday. In a post on X, he said 68 floors on the product's virtual building had been claimed by brands, products and founders.

Sinha's X profile describes him as a designer-turned-solopreneur who left a full-time job paying more than $15,000 a month to bootstrap products. Buyers pay to occupy a floor on a virtual tower. He has also sold timed aerial banners, which the site records as banner hours.

The Wednesday post gave a fuller snapshot. Sinha said the building was 851 feet tall, that 109 aerial hours had been booked, that floors had been viewed 266,292 times, and that people had visited from 127 countries. He wrote that a few people initially told him the aerial inventory would not sell.

TopFloor's website describes the product as a public leaderboard where companies pay to rank above competitors. There are no votes, no ranking algorithm and no editorial picks, the site says. Rank is set only by the total amount paid to list a company. An about page says the board reorders the moment a payment clears. Rules on the site say new listings start at a $1 minimum, that taking the top spot requires paying at least $1 more than the current leader, and that an existing listing can be raised by paying the difference. All payments are final.

An earlier product using the same core pay-to-rank mechanic, Outbid.lol, was launched on Aug. 19, 2026, by German indie hacker Jonathan Wilke; as of Sept. 9, 2026, market tracker AllRank.lol counted 507 pay-to-rank websites, 448 of them online, with $342,000 in self-reported payments.

Homepage data opened on Sept. 9 showed $1,103.02 paid in total, 68 companies listed, 20,168 visitors since launch, 109 banner hours and a current top price of $53.

Sinha posted the launch on Aug. 27, asking who would last the longest on top. On Sept. 7 he said he had built the product in 48 hours, that it had been live "for just a week," and that it had crossed $1,000, with 67 floors claimed, more than 19,600 visitors from 127 countries and more than 258,400 floor views. On Sept. 8 he said he had sold another aerial banner for 48 hours and crossed $1,100, pointing readers to a listing for the PreViz.ai domain.

The Sept. 9 post is the source of the latest round numbers. Sinha also wrote that he is "coming for $10k MRR soon." He did not state a current monthly recurring revenue figure, and the revenue totals have not been independently audited.
