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.

Yup, pretty much the info I managed to find on my own. The thing is interesting (being in the EU and all), and I e-mailed him to get some more detail (waiting for a reply) -- I posted it to share and because I wanted to see if anyone in the field knew him more or less directly

Thanks for your reply!

Something about "people like that" always puts me off. You know the kind of big grin, be with you next week, dripping in cash attitude :)

He probably does have the money etc. - but you'd have ot worry if he has the commitment to be a decent angel.... (most angels would be up and running publicly by now)

I could be wrong: just a gut impression I got.
