How would you value a company? One possible measurement is Return-on-investment (ROI). Venture capitalists expect about 5-10x their investment within three years. "Angels" expect 5x of theirs in 5 years. Another measure is Earnings-before-interest-and-taxes (Ebit). There are industry specific factors you multiply the Ebit with to get the company value. As a rule of thumb you can take 5. In general the value of a company is the net present value (NPV) of all future cash flows.
