Roundup: More Mobile Payments Experiments, Another AdMob Exec Departs

Another AdMob executive departs. This time for Mojiva: The New York-based mobile ad network grabbed Tony Nethercutt from Google to be its general manager for North America. Nethercutt was vice president of sales for Admob, where he created the sales and account management side of the company, before it was acquired. Before that, he guided YouTube’s revenue strategy, and worked at DoubleClick for four years. Nethercutt follows other senior AdMob executives like founder Omar Hamoui in leaving the company. Hamoui hinted that there may be four more unannounced companies to come from AdMob’s diaspora. We covered one, MoPub, here today.

GroupMe raises $10.6 million in a round led by Khosla: Like Kleiner Perkins, Khosla is spending big to get back into the world of the consumer Internet.

Samsung Galaxy S’s 10 million phone debut powers Android’s gains: Samsung posted an impressive debut, selling 10 million units of its Galaxy S phone within six months.

Mobile payments are gaining momentum with experiments from Wells Fargo: The San Francisco-based bank kicked off another trial with 200 employees who are using microSD cards to makes payments at participating retailers.

Even Google may get in the mobile payments game: Bloomberg BusinessWeek is reporting that Google may build a payment and advertising service that would let people buy basic goods by waving their mobile phones against a register. Considering their success so far with Checkout and in-app purchases for mobile developers, there are many questions about whether Google will be able to execute this idea well.
