"Founder Math Definition" T-Shirt

This is the uniform of anyone who’s ever pitched with bold energy and a broken spreadsheet. Founder Math is the unofficial language of early-stage entrepreneurs—equal parts logic, luck, and delusional optimism. It’s not always accurate, but it is consistent: underestimate the timeline, overestimate the outcome, and go all in anyway.

Wear this when you're bootstrapping, pre-revenue, or trying to make payroll with sheer willpower. It won't fix your cash flow, but it will make your cofounder laugh.
