SiliconBeat: "Don't even tell you spouse what you're working on"

SiliconBeat: "Don't even tell you spouse what you're working on": "Somehow, entrepreneur Dan Dobberpuhl managed to keep his 150-employee chip company stealth for two years in gossipy Silicon Valley.

Today, he has launched chip company P.A. Semi. He concealed his team inside two floors of the McAffee high-rise buildling in Santa Clara, and told new recruits they'd have to get on board before they found out what the company was doing. He told them not to tell their spouses what they were working on."
