A mobile payment system application, Fortumo helps developers monetize their products with inside-app payments. By adding the charge to a user's phone bill rather than his or her credit card, Fortumo creates one-click payments that are open to anyone with a mobile device -- whether users have a credit card or not. A recent Microsoft technology partner, Fortumo hopes to help app developers reach the estimated 5 billion cell phone users around the world.
"International credit card penetration is pretty low, especially in emerging markets," said Martin Koppel, chief revenue officer and co-founder of Fortumo. "[Users] would rather put micro-transactions on top of their [phone] bill."
