A coworker who likes betting told me he tracked everything in Excel. 7 months of development later, it became a SaaS. I work as a Data Analyst at a private equity bank. In January a summer intern joined who did a lot of sports arbitrage betting, placing bets across multiple bookmakers at once to lock in profit from the odds difference.

Nutshot Simulator – 31 days, 59K prompts, 142M tokens, ~$23K of Claude

@TechMomentum_ · X

One guy. Three hours. A flight simulator, built inside a browser.

Elon Musk tweeting about it. The money came from ad slots on the terrain, zeppelins, billboards, about $5K a pop, sold straight from his own account. No team. No pitch deck. Just a guy shipping alone with tools most of us already pay for. This is what solo looks like now. #buildinpublic
