Gowalla

[2] At the start of December 2009 it was reported that Gowalla had raised $8.4 million in a round of venture capital funding led by Greylock Partners and angel investors Chris Sacca, Kevin Rose and Jason Calacanis.

[3][4] It was acquired by Facebook on December 2, 2011, for an undisclosed sum [5] Gowalla, Inc. was based in Downtown Austin, Texas.

[6] On March 10, 2012, Gowalla announced it would cease operation and users would be able to download their checkins, photos and lists soon.

This is done either through the use of dedicated applications available on Google Android, iPhone, Windows Phone, Palm WebOS, and BlackBerry, or via the service's mobile website.

"Trips", which as of January 2010 [8] can be made by any user, linked together up to 20 related spots, grouped into categories such as Nature Hikes or Pub Crawls.

Some Spots and Trips are "featured" by Gowalla, being highlighted on their website and awarded a special status and icon.

This allowed the same features that applied to the iPhone 4 to be used on Android phones; it also updated the interface dramatically to introduce a new "Passport" look.
