Yes that's their official site and has been stated on numerous thread either here or in known websites too however I wouldn't trust them (not trying to be negative) since it said there "in cooperation with Genesis Mining" in which genesis mining had some problems and some bad reports plus the owner seem to abandon some users here (check his trust). His account:

I see no negative trust regarding cloud mining.
The negatve trusts come from signature campaigns and "dead" heardware that had malfunctions. As I would be purchasing clou mining then it is up to them and their devices are probably more efficiant than genesis-mining.
