SlotMaps, Art's AI assistant for slot machine players, has 13 paying members and $384.88 a month in recurring revenue (R2F Verified).
The rule for the AI team running it: at least one new paying member every month, or Art shuts it down.
An AI team merged 17 changes to Snagworth in one day last week. Snagworth was a price-report tool for Disney pin sellers.
Over 100 cold emails went out. 1 lead, 0 trials, $0.
Art shut it down the next morning, nine days before its deadline.
Taylor Caby put about $30 on UltimateBet in 2003. In 2005 he and a college friend started CardRunners, a poker training video site. Press had it above $3 million in revenue by 2007.
After Black Friday he built a fantasy sports site and sold it for $600,000 cash plus stock.
Our community site runs on a free database. On Oct 27 it hit the free limit, 5 million rows read in a day, and stopped answering. The forums showed nothing and nobody could sign up until 5 PM.
The fix was a cache, one index and $5 a month.
Art built an AI assistant for poker players and charged $99 a month.
10 people subscribed. 6 canceled inside the 8-day free trial. Total revenue: $594.
He stopped selling it and kept it as his own assistant.
Doug Polk's YouTube channel made about $400,000 in eight years. Upswing Poker, the business those videos pointed people to, made $20 to $30 million in seven.
His numbers, his words, 30 seconds. The channel was the ad.
@DougPolkVids is today's Rounder to Founder.
@DougPolkVids How it ended: in August 2025 they sold Upswing to ClubWPT Gold. Price undisclosed. The promise he made out loud was about the team: everyone working on Upswing kept their job.
"It was a great company, and I felt like we took it as far as we could."
Every build on R2F gets a score for how much of it we could check. Villain IQ, a poker hand-history app, got 38 out of 100: full marks for ownership and a live site, zero for revenue (none reported).

Doug Polk and his two partners each wrote a $5,000 check to start Upswing Poker. In month two they had to put in another $5,000.
He says it made money every month after that, for more than nine years. They sold it in 2025.
