Open source is different things to different people: software licensing scheme, business model, development model or community model. However we choose to think about it, though, across the board clever people are using open source to disrupt or change how markets behave.
Therefore, I found it fascinating to sit down recently with a German entrepreneur using an open source approach to disrupting the mobile application market. Paul Müller is the CTO and co-founder of Adeven, a mobile advertising tracking and analytics company based in Berlin that is entering the U.S market to compete with firms like Has Offers, Apsalar, Localytics and Flurry.
