The small print (http://biz.turbulenz.com/developers):

>We're sorry to hear that. Publishing with Turbulenz gets your game in front of a larger audience. We don't charge an upfront fee and we expect to help you achieve higher user and revenue numbers. If you still don't want us to publish it, contact us about alternative licensing options.

>Our mission is to create the greatest online gaming experience. We have heavily invested in the tools and technology to enable this experience and provide these to you free of charge. In exchange, we receive a 30% fee for helping you publish and promote your games to millions of potential customers globally. In fact, we take it a step further and provide services other online platforms don’t. For example, we take care of hosting, servers, analytics, marketing, payment processing, and we even provide developers with a live staging service (Developer Hub) to A/B test and optimize different development versions of a game.

So they're going for an app store model by using a free API as bait.
