SAN FRANCISCO—Streamezzo’s mission is fairly ambitious. It wants to unify the mobile ecosystem through an open and universally accessible software infrastructure and offer end-users the “ultimate experience” via a rich, multimedia environment. Sound familiar to Google’s Android initiative and Apple’s iPhone platform? Streamezzo thinks so.

Paris-based Streamezzo, about 80 employees strong, is one of those companies doing its part to address the wireless industry’s notorious fragmentation. Its Universal Software Platform is an end-to-end software framework said to overcome the challenges of fragmentation caused by competing mobile operating systems, networking technologies and handset designs. The platform is based on client-server architecture in which a client application on a device and Streamezzo’s content server software create an “abstraction layer” that operates above the fragmentation.

As for its 2-pronged mission? “From our (company’s) point of view, we are there,” said CEO Pierre-Emmanuel Struyven. That said, the company can always do better, and it is working on tools to offer third-party application developers, he added.

The company, whose investors include Qualcomm, is showing traction by partnering with Singapore’s MobileOne, which selected Streamezzo’s platform and professional services team to develop, deploy and run MiWorld Go, its new mobile music and video service.
