Everyone’s favorite NY-based mayor-maker just got more valuable. Foursquare has officially closed a Series B round of funding to the tune of $20 million, upping the pre-money value of the company to $95 million. The series was led by Andreessen Horowitz together with Union Square Ventures and O’Reilly AlphaTech Ventures. Companies like Yahoo and Facebook have courted a buyout of the location-based social site but were unsuccessful. Foursquare has been adding 15,000 users daily and now has 1.8 million registered users, and it seems there’s no slowing down its growth.
Foursquare also introduced a new feature that let you see the friends you have in common with another user. It’s similar to Facebook’s Mutual Friends where you can see users both you and the other person have added to their friends lists. The friend request emails of the company also sport a new look which now includes the profile picture of the user. This new feature should help boost trust in the system and increase the already explosive growth of the geo-location startup.
