It is simple if a company has the goods, they take it to the experts and they get their endorsements. If VLDI is simply a wizard behind the curtain then your best bet is to take the product to those that can't dissect the product. Once again do not pay any attention to the man behind the curtain!
The main reason a company goes to an investor conference is usually to build awareness to both institutional and retail investors. It usually becomes a magnet for raising capital, via, debt and/or stock offering and to push the stock price upward. Here is the problem with VLDI, they still have not been able to commercialized the VP product with a real company. Any astute investor is going to do their own DD and ask the tough questions like why after all these years, and all beta tests and field tests they still do not have a single real client with a commercial application?
