FourSquare Gets $1.35M in Venture Funding

foursquareFourSquare, the startup behind the popular LBS mobile application of the same name, has received $1.35 million in first round funding led by Union Square Ventures and including O’Reilly AlphaTech Ventures. Union Square Ventures is also an investor in Twitter, which is launching its own LBS feature in the coming weeks.

FourSquare lets iPhone and Android mobile users “check in” and notify friends when they get to a certain location, such as a restaurant or bar; the app also includes game mechanics. The NYC-based startup was founded by Dennis Crowley, who was behind Dodgeball, a similar mobile software service that was acquired by Google (s goog) in 2005.

The mobile LBS trend will be featured at our upcoming Mobilize 09 conference.
