Triposo is a social travel site and application created by ex- Google Dutch brothers Richard Osinga and Douwe Osinga with the help of Jon Tirsen. During development, Triposo received $3.5million worth of funding. In August of 2012, a second version of Triposo was released which included location-based software which allowed the app to tell the user recommendations depending on the weather, time, and other variables. The app has reportedly been downloaded 10 million times.
The app, available for iOS and Android, will show the user recommendations on where to go depending on information they've given to the app. This includes Facebook details. The app works without internet connection. In order for the app to work without connectivity, it downloads information about the users destination before departure.
