Microsoft has  invested $15 million in Foursquare. This strategic partnership will definitely assist Microsoft and Windows-powered phones with an enormous amount information about where to eat, what to see and do, where to stay for people on the move.

It is rumored that  data drawn from Foursquare and its 30+ million users, (and their more than 3 billion check-ins to date on the app)  will appear in a voice-activated assistant, to be released in the future which will go head-to-head with Apple's Siri technology.

This partnership will give Foursquare a new revenue stream and will provide it with additional expertise and possibly more features to its mobile phone app in the future.
