IdeaBuddy walks you from a rough idea to a business plan and a financial forecast, which is useful before you spend money on building anything, or when a bank or grant application asks for a plan. The lifetime deal is one payment of $69 for the Founder plan with one idea and one collaborator. Stack extra codes if you're testing several ideas. There's a free plan, so you can try the planning tools first.
