For what it is worth... google says this address is a place called Nextspace -- a co-working office. Seems weird to me that a company that can afford a 28nm chip without preorders can't find their own office.
This is a great question.
Here is the answer:
Uniquify was gracious enough to allow the entire HashFast staff to work inside of their offices. This is to both ensure that HashFast's engineering team is fully embedded with Uniquify, and to minimize any separation of HashFast's business and engineering teams during a critical time. In addition, we have rented temporary space for meetings, etc. in San Jose, and have access to additional space in San Francisco.
Since Simon and most of his team live in San Francisco, one should expect to us to soon relocate our offices closer to home. (I for one, hope this happens sooner rather than later

can you address some of the concerns others have stated in this thread? Such as the twitter feed, user accounts, private policy and etc. Your team appears to be a talented bunch. But so far, you wouldn't know that by reading this thread.
