The summary is written last although it goes at the beginning of your plan. It is the most important part of your plan. In this one page you must sell your idea. Your audience must be sufficiently interested to read the rest of your document. In your summary you must explain yourself, your team and your background, what your business is, what is exciting about the proposal, why it will succeed, what you want them to do - to invest how much, when - and what their reward will be.
