1. Run a well funded university lab, where resources of people and equipment are supplied by the government or even better run a lab that is overflowing with venture capital funds.
2. Come up with a novel idea of brain stimulation: perhaps stimulating at particular frequencies and at unique places. Do clinical studies first that succeed at showing this brain stimulation has a cognitive enhancement effect on healthy people. Publish your findings and release to media that this method is not like any of the others.
3. If you have the resources and the gumption, do a clinical study disproving the prevalent method (most researched, most used) of neurostimulation by a well organized research method that obfuscates the science.
4. You perform a media blitz saying that the prevalent method of neurostimulation is bad, will hinder performance. As the media only knows what is good and what is bad, they latch on to the paper and go ahead with "the previously reported good is now bad" type of story. Or if you don't have the gumption to do a full deception, just badmouth the prevalent method of neurostimulation when you can.
5. You release a product??
