In this interview, Alex Algard, the CEO of WhitePages.com, explains how the site has evolved from a directory assistance site to a broader people search engine, with  an expected 160 million people  on the site by the end of this year. Alex gives his take on how the WhitePages.com network is different from other competing online directories and how the site’s features provide users with the possibility to discover relevant information beyond mere contact info. Alex elaborates on the company’s advertising driven business model, which between the company’s various web properties (including 411.com) is projected to generate $70 million in revenue this year. Alex also touches on the role of social networks for people to stay in touch with their friends, as well as the notion of consumer privacy as the Internet is expanding the boundaries of the public and the private domain.
