We believe that openness is good for customers, good for the community and good for business.

To further advance the company’s long-standing investments in openness including interoperability, open standards and open source, Microsoft launched a wholly-owned subsidiary Microsoft Open Technologies, Inc. (MS Open Tech) in early 2012.

We are motivated by the core belief that open technology is a powerful enabler – and this concept underscores all of the work we do to create technical bridges between Microsoft and non-Microsoft technologies.

We are an organization of engineers, standards professionals and technical evangelists who are both experienced in and passionate about working with an equally diverse set of technologies.  In addition, we leverage our ability to marshal engineering talent from Microsoft on a project basis through the MS Open Tech Hub engineering program to help facilitate the exchange and evolution of open source engineering best practices.

Code talks within MS Open Tech. Many of our primary activities encompass building open source code and promoting the development and adoption of open technical standards specifications to deliver a more seamless experience across hardware, software and devices.
