They also typically seek companies that are "mezzanine" stage - the stage right before completing an initial public offering. This leaves earlier stage companies or companies seeking small amounts of capital with little interest from VC firms.
Most private companies would not want true venture capital in the first place. VC firms typically take a controlling interest in your company and usually want to have a say in day-to-day management. Most entrepreneurs are very hesitant to give up control of their business to outsiders.
A Regulation D Offering allows private companies the ability to leverage the smaller amounts of equity capital they need by efficiently raising capital from a number of individual investors.
