You may have thought that Yelp was crazy to turn down a $500 million offer from Google a while back, but the review site has gotten a nice little windfall from Elevation Partners, a private equity firm in Silicon Valley. The firm has invested a good $100 million into Yelp, and Elevation co-founder Marc Bodnick will also be joining Yelp’s board of directors. Could 2010 be a good year for Yelp? Reports came in that Yelp first achieved a positive cash-flow late last year, and that’s certainly a good start. Are you happy that Yelp turned down the deal from Google at the 11th hour, or do you think it would have been a good move?
