I still don't understand what stealth companies are all about (I mean the premise of "stealth").

If they say, we're working on X field with some Y tech, but can't discuss details, that's whole 'nother story. With some of these I have no idea what the company is, what it does, why it exists and even why anyone would use them.

If they want to avoid tipping competitors, there better ways of doing that.

I don't know. The whole thing seems silly.

I think the presumption is that you're already in the Bay Area, so all they have to do with the ad is to get you curious, and then it's not very much effort for you to just head over to their building and find out more in person.

Sucks for the rest of us, though.
