Groupon gets all the attention, but another deal juggernaut that should be on your radar is New York City-based Next Jump . The company runs group discount shopping programs for 90,000 corporations and organizations, and powers MasterCard's loyalty rewards program. Investment bankers are sniffing around. The company is on a hiring spree. It just hired its first chief financial officer, ex-Googler Angus Kelsall, who used to run Google's international businesses in Europe, the Middle East, and Africa. Another new addition to the executive team is Andrew Beranbom (he once ran Yahoo Shopping), who will take on the roles of chief social officer and VP of products. It acquired Y Combinator startup Flightcaster for its talent and plans to hire about 100 more engineers in San Francisco, mostly mobile. They will work under Sandeep Gupta, Next Jump's chief mobile engineer it nabbed from Yahoo last summer.
