Vienna-based social yellow pages startup Tupalo (a European competitor to Qype) has launched in the U.S. in partnership with CityGrid Media, a local media company "connecting the millions of businesses and customers on the web."
As a result, Tupalo now offers over 1 million business listings across the U.S.,
adding tens of thousands more on a daily basis. This, of course, also pits the startup against the major local (and International) player Yelp.
