Who it's for
First-time U.S. entrepreneurs who can describe their idea in one sentence but cannot yet say whether its pricing and costs can ever make money. It fits pre-launch founders testing an idea on paper, side-project starters deciding whether to leave a paycheck, and owners of very young businesses who want to sanity-check an existing offer before spending on ads or inventory.
About this playbook
This 14-day path turns a business idea sketched in your notes into a working financial model built with your own hands. Each day means one focused sitting of 25 to 60 minutes: classify your costs, compute contribution margin and break-even, size your cash runway and owner earnings, cap your customer-acquisition cost, then pressure-test every figure until it survives. You finish with a polished spreadsheet, a go, pivot or kill verdict on your idea, and the proven ability to rebuild the entire analysis from scratch on the next idea. Financial judgment is taught through one concrete model rather than abstract accounting lessons, so weak ideas get rejected before money goes in. It does not cover forming a legal entity, taxes, finding customers or running ads — only whether the underlying economics can work.
