There are no universally defined and accepted rules relating to the investing process of venture capitalists and they can at times, be even arbitrary. Within these limitations, what one can do, is to discern a pattern in them which are key to obtaining venture capital investment interest. The first process is to seek an investment which provide funds even before a company starts functioning. Such investments are based on a single individual who combines both the idea and expertise but does not possess enough capital and a venture capitalist steps in to bridge this gap.
This is followed by a start up investment stage, which concurs with the functioning of the company, but before revenues are generated. Then comes the early growth phase that corresponds to the period wherein revenues start coming in but they are not enough to become a major source of finance to sustain operations. This leads to follow on or what the industry terms as the "mezzanine" stage, wherein the venture capital firm steps in to enable sustainment of the operations. When the firm matures, the final stage emerges which involves the turning around of the investments and leveraged buy outs.
