My brother and I still rent our apartments, and we don't drive fancy cars. We're profitable because we pinch pennies.

Gregg Spiridellis, 34, one of the Spiridellis brothers who started JibJab.

The Spiridellis brothers seem happy to try numerous approaches to build their business in a way that lets them maintain their particular brand of humor, which Evan Spiridellis, 31, describes as "a little bit naughty but never quite R-rated." They're still not quite sure how to make money from their product, according to Cnet.

Yet JibJab, which recently added its Eighth employee, is not exactly a raging commercial success -- at least not yet.

And according to the Cnet article, they are not looking to advertising as a source of revenue. It's because producing online entertainment, particularly video, supported by advertising is "still a very shaky business model," and the brothers "won't risk the integrity of our brand by putting a can of soda in the foreground."
