It seems like such a simple move. Retailers are always giving out samples of their products to win customers over. Why shouldn't Davis, the CEO of LifeLock, give out his social security number to demonstrate how successfully his identity theft protection company could protect it. The idea came to Davis three years ago just minutes before he was supposed to give an interview on CNBC. After a quick call to determine the legality of what he was about to do, he gave out his SSN on the air and interest in the company exploded. "The phones went nuts, the enrollments went crazy," Davis recounts. "We had people not only calling to sign up but wondering how they could invest in us."
