I got an email from Harris Connect, which handles the alumni database for my old high school.<p>The company is old-school in many ways: it was founded 40 yrs ago(!); it requested I call in by phone to confirm accuracy of data; and one of the ways it makes money is by offering printed directories, including a $40 "deluxe" version. They offer a variety of other white label products, including online social networks, according to their site.<p>A bit of searching shows them to generate $50-100MM/yr in revenue with 500-1,000 employees (admittedly, the rev per emp is low compared to companies that leverage highly scalable technology).<p>As the Facebooks and Xings of the world look to monetize their offerings beyond advertising, I thought I'd share how this old-school company does it.
