What do Harley Davidson, Mentos, Dick’s Sporting Goods, Crocs, Eddie Bauer, Maybelline, Denver Broncos, University of Texas Athletic Department, and Purina all have in common? They're brands that have signed up with Vitrue , a social media marketing company -- just in the last quarter. Perhaps not surprisingly, it was their best quarter ever in terms of revenue and expansion. It's been a while since we've written about the company -- in fact, as far as I can tell, it has been about four years . Back then, Vitrue was just getting started, taking seed funding from Ron Conway and others. Since then, they've raised several million more dollars, but have also developed an SRM (social relationship management) platform that is used by some of the largest companies in the world.
