American Express will take a stake in the mobile adtech company, Kiip. The announcement was made eariler today by the company's founder 22 year old Brian Wong. Kiip's mobile ads unique because they reward app users with discounts, coupons and free products based on levels completed or by reaching milestones in non game apps. The company has already taken in over $15 million in investments before this deal, and they are expecting revenue to be in the eight digit range for 2013. This is a great idea for American Express in my opinion because we have already seen how much money Facebook has made off their mobile ads 41% of their revenue from the last quarter came in from mobile ads. Adtech companies are the new must have investment in everyone's portfolio in my opinion.
