Indie developer levelsio says his combined revenue and investment gains passed $10M/year.
- He aggressively cut SaaS subscriptions by vibecoding his own replacements, pushing profit margins to 94.5%
- Investment returns have exceeded business revenue for about a year, mostly via Vanguard S&P 500 ETFs
- Early Nvidia bets during the 2022 GPU shortage and a few lucky stock/startup picks added to gains
His playbook: spend less, earn more, invest the surplus, and let returns compound past the business itself.
