ah okay, there are some weird things in their FAQ:

Did your company desing your own ASIC chip?
No, we use chips designed and fabricated by our US partner

What company supplies ASIC chips for HashCoins?
Unfortunately under the terms of the contract we may not name the vendor/producer at the moment.

What US company can creat 500GH/has chips? I think none, and it is weird that they can't give the company name...
