Don't quit your day job until side project revenue replaces your salary plus one year of validation
Many founders quit too early, before validating that side project revenue is sustainable. Wait until your side project generates your current salary amount, then test for a full year to ensure it's legitimate and lasting. This de-risks the transition and proves the business can withstand seasonal fluctuations and market changes.
When to use
When your side project starts generating meaningful revenue and you're considering going full-time. Especially important if you have financial obligations or a high-paying job to replace.
Don't do this
Quitting your job as soon as the side project shows any revenue or matches your salary for a single month, without validating sustainability over multiple months or a full year cycle.
