Dive Brief: 

• Foursquare is set to launch a new ad product called "Tap to Tweet" that encourages users to tweet out a marketing message when they check in on the app. 
• The current price tag for the ads is $100,000. 
• MasterCard beta-tested Tap to Tweet during South by Southwest this year and Foursquare is looking for more brands willing to give the new feature a spin. 

Dive Insight: 

Foursquare is under a lot of pressure to improve ad revenue and trying out different products is the way to go when nothing has clicked yet. Using Twitter to send out marketing messages expands the ad's reach, but with no incentive for the user, it's questionable whether many will utilize the feature. MasterCard did offer card incentives, but brands may need to do more than that to encourage tweets from Foursquare users.
