Experienced Excel users will appreciate that textboxes default to having a border and white background. That‘s because they are often used to add comments or guidance to a user and so have to stand out. Otherwise a user would be foolish not to type words directly into the spreadsheet‘s cells. As equations can only be created in textboxes, the default settings are somewhat different; there is no border and no fill.
Angel Investors are typically much better investors for a long-term business plan that Venture Capitalists, although they do not come usually with the incredible network to help you succeed. Venture Capitalists are more interested in themselves and making money on their investment then what you get out of it or the future of the business with you in it. An angel investor is interested in you, the future of the business and the possibility of making a whole lot of money on their investment. Please consider all this when presenting your business plan to an Angel Investor.
