If you are talking to potential investors, here's the jist of what they want to hear:
1-Line description of the business model
Financials
Costs
Amount of $ needed
Investment Horizon
Milestones
Why are you and your team uniquely suited to execute this plan?
You need to demonstrate that you understand the business model and profit formula you will use to make money. Most investors have no interest in reading your business plan, but most say it is a good exercise to go through in your planning process. My entrepreneurship professor at USC Marshall said that a feasibility analysis is a better use of an entrepreneur’s time than drafting a 20-40 page business plan that will undoubtedly change.
