Cool, sounds like you discovered a life hack. Build something that can get $100m ARR while losing money, sell it, become billionaire.
Build something that can get 1k users. No in fact, build something that can get 100 users!
No offense, but you sounds like someone who has never actually had to build a business or product. It's hard to build something people use, even if its free. This isn't moviepass concept where they're literally selling $10 for $5, but even that's hard to sell! There are plenty of companies that try and fail to get tracking with moviepass economics.
