A public challenge: build apps with AI — nights and weekends, around a full-time 9–5 — until they earn $1,000/month. Net, after every cost. Every build, every dollar spent, every dollar earned gets posted. No highlight reel. Just the ledger.

Every product this challenge builds gets its own ledger — what it cost, what was bought, what it earns, and whether it's alive, sold, or dumped. These lines sum to the scoreboard above. Product links may become affiliate links — same price for you, a few dollars for the ledger.
