EBay said it acquired the data analysis firm Hunch to help it develop more recommendation technology for its online marketplace. Hunch analyzes data from social networks like Facebook and from questionnaires to make personal recommendations. EBay said Hunch will help it suggest relevant products for shoppers on its online marketplace. Chris Dixon, Tom Pinckney and Matt Gattis, who founded Hunch in 2009, will stay on at eBay and remain based in New York. The purchase price was not disclosed, although tech blog Uncrunched pegged it at around $80 million.
