They have a bank account number (Methud Holdings, nr 01999281124, Bank of America). Addresses and a support that's online a lot of the time.
I placed my order on the 26th of April which should have been launched at the 1st of May.
But they do not have a log out button, their servers test positive against heartbleed, no tax numbers, no reputation, domain is registered in December 2013 and there is no proof that anything is happening (except for processing orders).
When my account becomes active I'll post screenshots of it to proof that it's actually legit.
* about December: somewhere I read that in December they had their first round, although I can't remember where. That's strange if the domain had only been registered at that moment they would not have time to get customers or prepare all the software. It would seem like the first step of a new site.
* ps: I google searched the support's image which found David Marks's Linked In page (
