A quick check round the interweb shows that he is involved in many projects. I could not find a list of companies that he has actually invested in, nor the name of the hedge fund he used to work for. Many pages talking about many great things that are just around the corner. Improbably broad claims of expertise in "web/telecom" as well as all areas of renewable energy.

His English has a distinctive style so I think it's just him.
