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.
Microsoft Excel is a fantastic tool for analyzing scientific data. Microsoft Word is a fantastic tool for writing up scientific research. So surely Microsoft Office is the only software a scientist would ever require beyond that associated with specialist scientific apparatus?
