Microsoft here is just a temporary buffer for those who can't get H1-B visas. Once they're approved, MS will ship them to HQ, Redmond.
apike, one of the commenter in this thread, used to work for Apple, he might be able to give more info (and the location of this secret building).
Vision Critical looks promising since they seem to be growing quite rapidly. Another company in the same level with Vision Critical is Elastic Path.
90Degree Software used to provide BI solution as well and has a few ex-BO people (seems most of them came from Sales though). They got bought by MS either last year or this year.
One thing that strikes fear for me is the stability of these local companies. I saw somewhere that Vision Critical did a round of lay-off before. A friend of mine was going to replace my co-op position with 90Degree software couple years ago was met by a "Sorry, we made a mistake in filling our government paperwork thus unable to give any co-op opportunities for this intake". After that, I haven't heard any hiring/co-op placement anymore from 90Degree Software.
I also heard that once BOBJ was acquired by SAP, the culture seem to take a hit. Some people seem unhappy with the new overlord's action (cutting costs across the board). I suppose that's quite normal post-acquisition?
Indicee seems like a promising company a'la Web 2.0 for BI (saw the website, saw your CEO demo-ing the product in front of vicious audiences). When I browsed LinkedIN last time about Indicee, I saw many short-term employees, say 8months to 1.5 years kind of employees plus a view contractors. Care to share stories about that?
